There are two build options and the frame is available in medium to extra large sizes, with the medium sporting a 464mm reach. Along with generous reach, in the weakest geometry position, the Chilcotin has a 63.8 degree head tube angle, 76.9 degree effective seat tube angle, and 438mm chainstay length on the touring bike 166mm when paired with a 170mm fork.
Frame details
The biggest update on the new Chilcotin is the change from 26 “to 29” wheels. There’s also a switch to 157Trail rear hub spacing, which uses a wider flange 157 hub paired with a 73mm bottom bracket shell. Knolly believes this gives them most tire size options, easily freeing up to a 2.6 x 29 “tread. The 157Trail hub also offers more bead clearance while maintaining the ability to run up to a 36 tooth crown.
The bike is built using 6066 series hydroformed aluminum alloy tubing. Knolly chose this aluminum for its combination of high tensile strength and excellent durability. It allows them to create more complex shapes that maximize torsional stiffness and create what they feel like a “predictable high performance ride”. The bike has an open cockpit down tube protector, internal cable routing and water bottle holders.
Knolly’s OSD (Offset Straight Seat Tube Design) design allows riders to shift from a more effective pedaling position to a more aggressive position for a harder ride more easily. This allows the saddle to be very low on steep terrain with full rear wheel travel. Plus, it offers space for up to 175mm upright on medium-sized frames and 200mm + on large and extra-large frames thanks to a straight, uninterrupted seat tube.
Suspension
Knolly uses its Fourby4 suspension platform for the Chilcotin. It has a progressive lever curve designed to handle big hits while maintaining initial feel along with plenty of mid-stroke support. The rear of the bike is longer than Knolly’s trail and freeride bikes to increase stability at high speed.
The Fourby4 suspension is designed to reduce the impacts of the brake squat, which Knolly says allows the rear wheel to maintain greater contact with the ground and carry speed over more technical terrain.
The bike’s pedaling traction is designed to ensure consistent pedaling performance, even in difficult spots, so riders can pedal more easily whenever they need to get more power, according to Knolly.
Geometry
The geometry of the Chilcotin is adjustable (loose or neutral). The adjustment to change the geo is a simple bolt removal where a cyclist can slide the shock back or forward, then reinstall the bolt. This adjustment changes the effective seat tube angle from 77.6 degrees in neutral to 76.9 degrees in slack mode. Likewise, the head tube angle changes from 64.5 degrees to 63.8 degrees.
Construction options
The Chilcotin platform has one chassis but two suspension travel options. The Chilcotin 150 construction kit features 150mm of rear wheel travel paired with a 160mm fork. The Chilcotin 166 construction kit increases rear wheel travel to, you guessed it, 166mm, with a 170mm Fox 38 Float or RockShox Zeb.
There are two build kit options, DP and EC along with two color choices, “Moody Blue” and Raw. The bike will be available in December at retailers and online with prices starting at $ 5,300 USD.
