Charge Plug 5 review

Charge may be better known for its single-speed town bikes and aftermarket saddles, but the British brand is expanding and has some major changes and additions to its product lines. While the Cooker range caters for mountain bikers, and the Grater for the leisure cyclist-cum-commuter, the Plug range’s boundaries are a little harder to define. The Plug 0 is a single-speed, bullhorn-handlebarred affair while the Plug 1 gains cantilever brakes, drop bars and rack eyelets. As the range develops, disc brakes emerge alongside double chain rings, until we arrive at the Plug 5 – an all-singing, all-dancing titanium affair costing, as near as makes no difference, £2,500.

Herstory: Female Olympic Winners Past to Present Part-2

We are just two weeks away from the 2016 Summer Olympics in Rio de Janeiro, and the excitement is building. Federations around the globe have submitted their final rosters to the Olympic Committee and athletes everywhere are spending the coming weeks dotting i’s and crossing t’s for this pinnacle event of our sport. We’ll be talking about today’s Olympians a lot in the coming weeks but before we do, let’s pedal backwards in history and take a look at the winners of the past Olympic Games. Read more...






Stan's No Tubes Factory Tour

Big Flats, New York is not a mountain bike mecca. Let's be clear on that. It's certainly not a place where you might expect to find the headquarters of one of the industry's leading high-end wheel manufacturers, but sitting just off of Interstate 86, and about 15 miles directly south of the Finger Lakes region you'll find the home base of the brand synonymous with tubeless wheel and tire innovations. Stan's No Tubes is celebrating 15 years of delivering game-changing innovations that began with sealants and rim strips and has since evolved into a much more comprehensive range of products for everyone from Olympians and World Cup athletes, to park rats, to your weekend warriors looking to make it back to the trailhead before dark.

Are 27.5+ bikes faster than 29ers?

Unless you’ve been living under a rock for the past year or so, you’ll probably have heard a lot of speculation about plus-size tyres. Everything from far-fetched marketing nonsense to vitriolic condemnation has been plastered all over the internet: often in all capital letters, so you know it must be true. At BikeRadar, we like to find out for ourselves what really works and what doesn’t, so we set out to try and answer a simple sounding question: could plus-tyres ever be faster than normal ones?

How to adjust the rebound and compression settings on your mountain bike

In its most basic form, suspension starts with a spring. A spring can be constructed from coiled metal, just like a mattress spring, or from a gas, usually air, inside of a sealed chamber. A coil spring feels linear, meaning the amount of force required to get it to move is consistent throughout the entire range of travel. Conversely, an air spring becomes progressively firmer as it is compressed. Read more...




6 ways to pedal like a pro cyclist

Optimum pedalling style is one of the eternal debates of cycling. Is it better to spin quickly, or grind away in a big gear? Should you climb seated or standing? While most studies are still inconclusive, we've gathered six examples from the world of pro cycling for you to try. Cycling has a fixed range of limb movement due to the cranks controlling the circular motion the feet and legs can take. Muscle movement patterns and styles are much closer between pro cyclists than they are within a group of elite runners, for example. Read more...



5 Adventurous Alternatives to Bikepacking

Lots of us dream of loading the bike for a multi-day backcountry adventure, but then reality sets in. You have the bike, but you might be looking at hundreds of dollars, if not thousands, to outfit your bike and make it ready for bikepacking. That assumes the bags will fit on your current bike, and let’s face it, your everyday bike probably isn’t the best tool for the job. That doesn’t mean you can’t see the wilds from your bike saddle, you just have to use a little ingenuity, creativity… and some cash never hurts. Read more...








Ritchey Streem II Handlebar Review

Ritchey Logic’s Streem II handlebar ($299.95) was intro’d in 2015, and I bolted them onto the Ritchey Carbon Break Away bike build I did here. I’ve been riding it for over a year now – which qualifies it for this long term test. The Streem II is Ritchey’s answer to the lightweight, fully carbon, handlebar conundrum that may or may not be a question in your life.  The only thing left to answer is whether you like the shape and feel for yourself.

Wider Is Better? (Roadbike Tyres)


Tyres are the only constant on your bike that’s continually in contact with the road surface, therefore tyre selection and preparation can have an overwhelming impact on bike handling and rider comfort. For many years 23mm wide tyres were the default choice for road bikes with many racers using 21s or even narrower, but these days 25mm tyres have become the most popular option for both professional and amateur riders. Why they switch it? A new marketing hype? Or they really have a true benefit?

Comfort


Wide tyres can provide more comfort than narrow tyres, all other things being equal. 25mm tyres have been tested and proven to perform equally as well as 23mm tyres. With a larger chamber of air between you and the road, a wider tyre allows you to drop the pressure without running the risk of a pinch flat. The lower pressure increases the amount of cushioning you get from the road, improving your comfort. Why is comfort important? You can get more from your body when you’re comfortable than you can when you’re feeling battered and bruised. “Smoother is faster”, as Specialized is fond of saying.

Rolling resistance

Rolling resistance is the energy that is lost when the tire is rolling. The main reason for the loss of energy is the constant deformation of the tire. Lots of factors determine rolling resistance, such as tyre width, profile, air pressure, material quality, and the constant deformation of the tyre as you ride. Cast aside any intuitive thought process that you might harbour, wider does not necessarily mean harder to pedal or slower at all. In fact, the figures mount up in support of the opposing view.

“Wider tyres roll faster,” says Dave Taylor, Marketing Manager at tyre brand Schwalbe. “The answer lies in tyre deflection. Each tyre is flattened a little under load. This creates a flat contact area. “At the same tyre pressure, a wide and a narrow tyre have the same contact area. A wide tyre is flattened over its width whereas a narrow tyre has a slimmer but longer contact area. 



“The flattened area can be considered as a counterweight to tyre rotation. Because of the longer flattened area of the narrow tyre, the wheel loses more of its roundness and produces more deformation during rotation. However, in the wide tyre, the radial length of the flattened area is shorter, making the tyre rounder and so it rolls better and therefore quicker.” “In practice, the energy saving is even greater than in theory as the elasticity of the tyres absorbs road shocks, which would otherwise be transferred to the rider and so saves energy,” says Dave Taylor.

Cyclist have tested that claim, you can read the details here and below its the summary:


And another one test results from Wheel Energy in Finland. The last column shows work (Watts) to keep constant speed (40km/h) of a test drum against the resistance of a loaded (50kg) tire.”


Aerodynamics

As usual, it gets more complicated when it comes to aerodynamics. It’s obviously true that a narrow tyre has a smaller frontal area than a wide tyre, but it’s useful to think of the tyre and rim together rather than just the tyre in isolation. Wider tyres require wider rims to perform at their maximum and the latest aerodynamic wheels have wider rims shaped more like a ‘U’ rather than a ‘V’ to create a curved profile. Air turbulence is less and makes the bike easier to handle in crosswinds.

Wheel rims have generally started to get wider over recent years, partly because of the trend towards wider tyres. “The current trend toward creating wheels with wider rims stems from the trend toward increasing the diameter of tyres, particularly in competitive road racing,” says Paul Lew, Reynolds’ Director of Technology and Innovation. “Wider rims offer better mechanical support to large-diameter tyres and are needed to help separated airflow reattach to the rims.”


Run a 25mm tyre on many narrow rims and you get an ice cream effect: a big, bulging scoop of tyre sitting on top of a skinny cone of a rim. The mismatch between one element and the other doesn’t result in a high level of aerodynamic efficiency. However, wider rims have been designed specifically for use with wider tyres, the rims and tyres work together aerodynamically. Airflow that is separated by a wide tyre is able to reattach better to a wider rim than to a narrow rim, reducing drag.

Handling

The mountain biking world has been onto lower-pressure-equals-more-grip-and-control for years now. This came about with the advent of tubeless tire systems and crazy low pressures, but the results spoke for themselves. Massive amounts of grip were made available and the riders just kept getting faster!


It is the same for wider road tires. Bigger casing means a larger contact patch. Drop the tire pressure a bit and that contact patch just became even bigger. Lower tire pressure also allows the casing to deform when cornering aggressively the tire can grip to irregularities and variations in the road surface more effectively, allowing you to lay it down in a corner with less chance of dropping the bike. The direct result is greater confidence when cornering and more control overall.

Why not go super-wide?

If this is true, why stop at 25mm? Why don’t we use 35mm or 45mm tyres on a sporty road bike? First, a super-wide tyre wouldn’t work aerodynamically with existing wheel rims. Second, most road bikes don’t have enough clearance (a few still struggle with 25mm tyres). And third, wider tyres would add greatly to a wheel’s rotational weight and dull the acceleration. For all these reasons, it seems that 25mm tyres have become the new 23.

Cannondale Synapse Carbon 105 Disc review


We reviewed the Synapse Hi-Mod a while back and were mightily impressed but considering the price you’d expect that. It did leave us with a burning question, though – could Cannondale repeat the success for under £2,000? We decided to find out. Cannondale has made a name for itself as a pioneer of successful (and sometimes unsuccessful – Headshock anyone?) new tech. Cannondale invented BB30, which is now widely adopted by many manufacturers. It was one of the first to produce a bike designed specifically for cobbles, and the Slate is at the forefront of the hip gravel bike movement. The Synapse Carbon Disc 105 takes a lot of the ideas from the expensive models and distills it into a cheaper package. Read more...

Choosing a steel, aluminium, titanium or carbon road bike

If you’re shopping for a new road bike, you’ll be inundated with choice, which can make choosing the right bike for you a tricky decision. There are many factors you can use to filter the choice, from price, specification, style of riding, brand allegiance or even colour. Sometimes the choice can come down to the material the bicycle frame is made from. There are four common materials used to build road bikes: steel, aluminium, titanium and carbon fibre and the material can influence the ride and purpose of the bike, so it's good to know the key differences before you make a decision.

Cycling Sunglasses


Sight is an amazingly complicated sense. Your eyes continually move and adjust, receiving a constant flow of information. Normally, all this activity happens routinely and without noticeable strain. When cycling, however, you are affected by glare and the sun’s ultraviolet radiation. Glare is annoying and discomforting causing your eyes to work harder, contracting your pupils, narrowing your eyelids and causing muscle fatigue. It also reflects off roads, traffic, water, concrete and the glass in buildings.

This is why quality eyewear is such an important cycling accessory. Besides being a fashion accessory, cycling sunglasses shield your eyes from bright sunlight and harmful UV rays, and also offer protection from the wind, rain, dust, grit and bugs that can impair your vision.

What should you look for in a pair of cycling sunglasses? Well they differ from regular sunglasses in that they have a wraparound design so they sit closer to your face. The frames are usually thinner and they're made from lightweight and durable materials, and the lenses are lighter too, typically shatterproof and they come in a vast rainbow of tints to suit different lighting conditions.

Fit and Comfort

When picking out your new sunglasses the first thing to look at is face size. Sunglasses frame size should closely mirror face size - smaller frames work better with smaller faces and vice versa. Frame size refers to the actual fit of the sunglasses. This is a general rule of thumb and not to be confused with the coverage of the sunglasses. They do make oversize stunner shade for small faces. For a more specific look at the size of a pair of glasses, look at the dimensions. This is often written as three consecutive numbers: (Eye Size) – (Bridge Size) – (Temple Size).



Eye Size
This is the horizontal measurement from the outside edge to the inside edge of one lens. Typical widths are 40–62 mm.

Bridge Size
The bridge is the distance between lenses. Typical widths are 14–24 mm.

Temple Size
This is the length of the temple piece, also known as the arm piece or ear piece. Typical lengths are 120–150 mm.

Fit is the a key criteria when choosing a new pair of cycling sunglasses. They need to be comfortable with no pinch points or excessive tightness, and they need to sit close to your face and not obscure your vision. Cycling sunglasses can sometimes be adjusted to preference. These are the two key areas that will affect comfort the most. The nose bridge will, in almost all cases, come with some kind of rubberised or soft touch cover to both help the glasses stay in place and also prevent the plastic underneath from rubbing on your nose. 

Whether the nose bridge is built in or replaceable depend on how expensive the glasses are. Oakley, for example, have a fully replaceable bridge and their performance glasses come with a spare in the hard case. Stating the obvious, though, everybody’s nose is different and what works for one person won’t necessarily work for everyone else, so trying on a set of glasses in your local bike before you buy is advised. 

The tightness of the arms is something to be aware of as well. Arms can be flexible or rigid, Most are covered with a rubber material to grip your head and stop them moving about. Another important feature of the arms is length. And, more specifically, how the length of the glasses interacts with the retention system of your helmet. So trying sunglasses with your helmet on its very advisable.

Generally, a sign of good fit is that you forget you're wearing them when you're cycling.

Lenses


Lenses come in a huge range of tints and colours from dark black to protect your eyes in bright sunlight, to yellow for boosting contrast in poor light. The first choice with lenses is in choosing whether you want something with two individual lenses or large one-piece integrated lens. In performance terms, the one-piece lenses usually have a great degree of coverage, as they don’t have a complete gap where the nose bridge sits, and will often be constructed to come further around the side of the head, meaning you won’t get that irritating effect when the lens ends right in the corner of your vision.

Cycling sunglasses with interchangeable lenses are common these days, and very popular, for good reason. The great thing about a set of glasses that come with interchangeable lenses is that it increases their versatility. A lot of glasses with interchangeable lenses will be supplied with at least two options, while many brands will also offer a wider range of aftermarket lenses, which you can pick and choose from. Choose a pair of glasses with several sets of lenses and you are going to be prepared for most typical cycling conditions.

Some manufacturers make photochromic lenses that get lighter or darker according to the conditions, but the range they offer is more limited at present than specific lenses, but can be a useful and appealing alternative if you don't want to have to worry about changing lenses.

Some lenses are vented or have an anti-fogging coating to help reduce fogging when you sweat. Some manufacturers apply a hydrophobic coating to help rain run off the glasses. You also want to make sure the lens has UVA (UVA account for 95% of the UV radiation reaching the Earth’s surface. UVA rays do not vary in intensity throughout the year and although they are much less intense, they are 30-50 times more prevalent than UVB rays. In recent studies, UVA rays have also been shown capable of contributing to the development of skin cancer and photoaging, and have been linked to the development of certain types of cataracts.) and UVB (UVB are super intense and the primary cause of sunburns and cancer, and can be very hazardous to the eyes. UVB Rays vary in intensity throughout the year and are much stronger in the summer months between the hours of 10 am and 4 pm – this is the time of year when the earth’s axial tilt is angled towards the sun, causing UVB Rays to be more focused.) protection. 

Some cycling sunglasses offer a prescription option, either with the sunglasses lenses made to your prescription or with clip-in lenses behind. One useful extra that some have is an anti-scratch coating. Anti-scratch coating is just an added layer of protection that means you won’t ruin the lenses quite as easily.

Lenses Colurs Guide



Mirrored Lenses
Mir­rored lenses are best for bright sunny days. These lenses typ­i­cally block the most light mak­ing rid­ing into the sun more enjoy­able.  There are many col­ors of mir­rored lenses avail­able so it’s easy to match your lens to the color of your kit. These lenses also do the best job of hid­ing your eyes, valu­able if you are prone to pain-induced tears or are plan­ning a mid-ride stop at the beach.

Orange or Yellow Lenses
Orange/yellow lenses are best for low-light rid­ing con­di­tions (e.g. the light­ing con­di­tions seen either at dawn or dusk). These lenses help to enhance low-light rid­ing con­di­tions by bright­en­ing up the road or any­thing that is on it. 

Clear Lenses
Clear lenses are designed for night rid­ing or rid­ing in the rain. While they won’t block any light, they will block debris. Select clear lenses if you’re going to be rid­ing at night or going out dur­ing a heavy rainstorm.

Photochromic Lenses
Pho­tochromic lenses auto­mat­i­cally adjust to chang­ing light con­di­tions. They will darken when the sun gets brighter and lighten when the avail­able light lev­els start to decrease. If you ride multi-day or all day, a pho­tochromic lens, while a bit costly, might be your best bet  so you’ll never have to worry about whether or not you have the right lenses in.

Gray Lenses
This is a neutral color that provides natural contrast and gives true color perception. It's a good, general-purpose color.

Brown and Amber Lenses
These are the best lens colors for high glare. They allow excellent contrast and their dark color minimizes eye strain. They're effective for absorbing most blue light waves, which sharpens visual acuity, improving depth perception and contrast in variable light conditions. On the down side, amber distorts colors, making greens greener and causing neons to fade.

Canyon Strive AL 6.0 Race (2016) review



Launched just last season, the Canyon Strive has all of the hallmarks of the perfect enduro race bike. Available in both carbon and alloy versions, the Strive’s lightweight frame construction, great sizing and innovative Shapeshifter technology — that lets you change the attitude and travel of the bike at the push of a button — promises to make the Canyon every bit as fast uphill as down.

Reviewed: gevenalle audax brake levers and shifter mounts


We’ve reviewed the gevenalle shifters in the past and found much to like, and saw the latest from the portland company at nahbs 2016. They’re not for everyone, but if you are a rider who prioritizes reliability, simplicity and are on a budget than you should take a look. I tried out gevenalle’s most affordable option, the audax shifter mounts two weeks ago at the 2016 lost and found gravel race’s 60-mile route and came away with these impressions. Read more...
