Exactly What’s New On the Trek Supercaliber Gen 2?

The Trek Supercaliber Gen 2 brings more capability for technical terrain while keeping things lightning-fast.


But we know the racing snakes among us want the nuts and bolts about what they’re getting with this iteration, so here are the most common questions the guys at Trek get asked about the Trek Supercaliber Gen 2:

What is different about the frame compared to the previous generation of Supercaliber?
The frame is completely new to make it a more capable bike without sacrificing any of the speed. The travel has been increased from 60mm to 80mm rear travel and the front suspension has increased from 100mm to 110mm. The geometry has been updated with a slightly longer reach and slacker headtube angle. There are now two unique Supercaliber frames. There is a lightweight SL frame and a super lightweight SLR Supercaliber frame. The frames look identical, however the SLR frame has a lighter carbon layup and does not have the internal cable routing guides on the mainframe. There is also a new RockShox SIDLuxe IsoStrut on all models.

What is the maximum fork axle-to-crown and/or travel?
The bike is designed for a 110mm travel fork, but it is compatible with 100 and 120mm forks. This allows the rider to choose the fork and travel that best suits their preference for geometry, weight, and performance. The maximum axle-to-race is 525mm.

What size tyre is spec’ed on the Trek Supercaliber Gen 2?
All models get 29×2.4” tyres except for the Supercaliber SLR 9.9 XX SL T-Type which has 29×2.2” tyres on it to help save weight and because the new RockShox SID SL fork on that model has a max clearance for 29×2.35” tyres.

Are these bikes tubeless compatible? What additional parts are required?
Yes. All models are tubeless out of the box. They include TLR strips, valves and sealant.

Is the new frame compatible with the previous FOX IsoStrut?
No, the frame is only compatible with the new RockShox SIDLuxe IsoStrut due to several dimensional changes (eye-to-eye, stroke, diameter).

What is the recommended sag for the new RockShox IsoStrut?
The new Supercaliber was designed around 25% IsoStrut sag for a balanced level of rider efficiency and suspension response. Riders can also adjust setup pressure throughout the 15-35% sag range, as marked on the new RockShox IsoStrut, to fine tune their setup based on preference and riding conditions. Higher pressure/less sag = higher ride height and firmer and a more efficient pedaling bike, while lower pressure/more sag provides lower ride height and softer and more compliance through rough terrain.

Is there any special suspension setup knowledge needed for the RockShox IsoStrut?
There are sag gradients marked on the strut to help you easily setup and tune your preferred sag. Also, the IsoStrut reboud has numeric labeling: 10 is slow rebound and 1 is fast rebound. Just like the podium you’re racing for. #1 is fastest and higher numbers are slower. (We hope that helps you remember.)
