Tour Rig: Specialized Sequoia

Specialized Sequoia

The Specialized Sequoia was first designed by Tim Neenan in the early 1980’s. Later, Jim Merz improved upon the design of this versatile bicycle. While the 1980’s steel Sequoia had a certain panache, the aluminum models of the 2000’s somehow lost their sex appeal. The Sequoia died out in the 2000’s.

The new and old Sequoia

The new Sequoia is positioned squarely between Specialized’s two “adventure” models: It’s more dirt-worthy than the Diverge, but lighter and faster than the AWOL. Complementing the bike is a full line of bags, tires, and wheels designed for the path less traveled. Geometry-wise, this is a model that “skews the line between a traditional road bike and a dedicated touring rig”. A long wheelbase (1053mm / 41.46in for a size 56) matches up to a low bottom bracket (292.5mm / 11.52in for size 56) while 71.5 / 73.5 degree head tube and seat angles have been chosen to keep the handling from being too lazy.


Bikepacking setup

The Sequoia uses custom drawn tubing (it calls “tour tubing”—the same name as the original 70s version) for each frame size, from 50cm to 61cm and it shows. There’s also a custom fork, with rack, fender and cargo cage mounts, as well as a new headset. Thru axles, flat mounts, internal routing, and wide range 1x drivetrain systems had taken over the drop bar market, making a bike like this almost as capable as a mountain bike in terms of gear range. The Cobble Gobbler post and its funky design is met at the cockpit with their new drop bar, which has 20mm rise, flair and a shallow drop.

Flair and shallow dropbar

There are rack and fender mounts, as well as braze ons for a third bottle cage. Other details include internal routing for generator lamps, clearance for a 45mm tire, and new thru-axle hubs. The brake and gear cables are managed really neatly under the downtube, and if you want to use Di2 gearing, this frame is ready and surprisingly, this bike uses a threaded bottom bracket shell. 

Internal route cable fork

The most impressive feature of this bike is the carbon fork. Thru-axle, internal routing, flat mount disc brakes, hidden fender mounts, drilled crown, cargo cage attachments and designed to carry a front load with rack mounts. All with around 50mm of clearance. This fork is what everyone has been asking the industry to make for some time now. The Sequoia available in three different models and six different sizes. Each frame size uses a different blend of tubing to achieve the same ride feel. All three bikes will be steel, but only the top two will come with the carbon fork.



Highlight:
  • Electronic drivetrain ready
  • Disc brake with flat mount
  • Swallow 45mm tyres
  • Chromoly frame with carbon fork
  • Mounting for front and rear rack
  • 3 bosses for bottle cage, you can add 2 more bottle cage in fork if you don't install a front rack
  • Thru axle

Glossary:

Headtube: The head tube is the part of a cycle's tubular frame within which the front fork steer tube is mounted.

Headset: The headset is the set of components on a bicycle that provides a rotatable interface between the bicycle fork and the head tube of the bicycle frame. A typical headset consists of two cups that are pressed into the top and bottom of the headtube. Inside the two cups are bearings which provide a low friction contact between the bearing cup and the steerer.

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.
