Tech Talk: Cervelo P5X

Cervelo P5X

Cervélo are boldly claiming that the P5X is the ‘most technologically advanced triathlon bike ever made’. The end result is a machine that aims not only to be fast in a racing environment, but also one that is practical when training and travelling. To this end, the P5X has customisable storage with various containers and mounts for bottles, tools, food and spare clothing, and also a folding aero bar 

Disc Brakes and QR

It seems that disc brakes are the way forward for tri bikes and discs will become more prevalent. The addition of disc brakes plus the nature of the frame means the addition of thru axles as well with a 142×12 rear and 100×12 front QR thru axle. The brakes are flat mount with 160mm rotors and TRP’s HYRD mechanical/hydraulic calipers.

You can have the most aero bike in the world in the wind tunnel, but if you’re taping gels to the top tube and strapping tubes to the frame, those numbers go out the window. To make sure the bike is as fast as possible, the P5X features three main storage compartments that are both built in and removable depending on the location for the perfect amount of storage.

On the top tube, the SmartPak features a structured zippered pouch with internal organization for gels, a center section for deeper storage, and even a small tray for electrolyte tabs. It can be removed from the frame completely if not needed and includes a cover for the hole in the frame. 

Stealth Box

In front of the bottom bracket is the Stealth Box which is the one completely integrated storage compartment. Nestled inside the opening is a small box which is big enough to hold a spare tube, small co2 inflator, and a multi tool to keep the weight down low. Last, the SpeedCase is the third storage area which is also removable and bolts to a standard water bottle mount on the down tube. There is a secondary water bottle mount on top of the SpeedCase when the box is in use so you don’t lose the mounting location.

Additional bottle storage is offered behind the saddle with a built in mount. The seat post can actually pierce the upper beam and is held in place by a single pinch bolt, but the post can be cut at the bottom for maximum aerodynamics. The adjustability of the seat post allows a 74-81º effective seat tube angle

Front Review

Along with storage and aerodynamics, the frame features a number of impressive features to make it fit a huge range of rider and to make it easier to travel. Instead of a more traditional steerer tube and spacer arrangement, the P5X essentially uses a seat post for the aerobars that can be raised or lowered to the desired position. You can adjust 112mm of sliding stack and 91mm of reach adjustment along with a base bar that can be flipped 180º with 0 to 12º of tilt. Electronics can be integrated into the frame behind the handlebars with a window built in for junction boxes. Between the elbow pads you’ll also find another water bottle cage mount.

Break The Bike

Another feature to make your life easier when travelling with this bike, you can break the bike down, remove the four screws that hold the base bar together and it divides into two pieces which are then held to each fork leg with a neoprene sleeve. That allows you to slide the bike into the case without messing with the headset and preserving most of your settings.



Highlight:


  • 3 box storage, 2 removable and 1 integrated
  • No seattube and seatstays
  • Using QR in front, TA in rear wheel
  • 3 bottle mount, behind bar, behind the saddle and in the downtube
  • Folding bar!



Glossary:

Bottom Bracket: The bottom bracket on a bicycle connects the crankset (chainset) to the bicycle and allows the crankset to rotate freely. It contains a spindle that the crankset attaches to, and the bearings that allow the spindle and cranks to rotate. The chainrings and pedals attach to the cranks. The bottom bracket fits inside the bottom bracket shell, which connects the seat tube, down tube and chain stays as part of the bicycle frame.

Seatpost: is a tube that extends upwards from the bicycle frame to the saddle. The amount that it extends out of the frame can usually be adjusted, and there is usually a mark that indicates the minimum insertion (or maximum extension)
