Chilcotin 151
We set out to design the Enduro race bike’s next generation and are proud to release the Chilcotin 151. The goals were simple: make the bike fast as hell and super manageable even in the worst race conditions. This Enduro bike features 29er wheels, a completely new design, our industry-leading patented Fourby4 suspension and two suspension travel options for when you need to push your performance to the next level.
The Chilcotin 151 also includes 157Trail rear hub spacing, which uses the wide flange 157 hubs with 73mm BB shells, our patented offset straight seat tube design (OSD) and human-centric sizing so it'll fit a broad range of riders.
It’s ready to race Enduro and tough enough for large freeride hits. Available in 151 or 167mm of rear travel, the Chilcotin is one of Knolly's most capable and versatile long-travel 29er bikes. You'll PR your favourite descents and have confidence on steeps, jumps and drops, all while easily climbing up tracks for repeat sessions.
At Knolly, we take the harder road to better design simply because it delivers better product performance.
Complete bikes ship unassembled & require a full build. Spec is subject to change without notice. If you have any questions, contact us at info@knollybikes.com.
The new chilcotin
Our patented Fourby4 suspension is designed to maximize rear shock performance and available traction in every situation, no matter how crazy things get. It reduces brake “squat” and enables your wheel to maintain contact with the ground to maximize your speed through the most challenging terrain. And our legendary pedalling traction ensures performance - even in the jank - so you can get on the gas when you need to eliminate another second off your time.
157Trail
We feature 157Trail rear hub spacing which uses the wide flange 157 hubs with 73mm BB shells. This spacing provides the most options for tire size and can easily clear tire widths up to 2.6. With 157Trail, heel clearance is exceptional and chainring clearance remains huge at 36T.
OSD
Our patented offset straight seat tube design (OSD) allows our riders to transition effectively between a highly efficient pedaling position and the “attack position” required for aggressive riding. It enables the rider to drop the saddle on the downs and is critical in allowing maximum rear wheel travel while keeping the back wheel away from the seat tube under full compression. This design allows us to run 200+mm dropper posts because our seat tubes are straight and un-interrupted.
