![]() ![]() ![]() If you are a freeride, park rat and want to run full 27.5, you have to install a lower headset cup to maintain geo and ride height. If you want to run a mullet/mixed wheel set up, simply put the bike in the High position and change out the rear wheel to a 27.5 and you are ready to rock. With this setup riders can choose between a high or low geometry setting via the Mino Link. In its default packaging, the new 2022 Trek Session ships with 29-inch wheels front and rear. The Trek Session frame comes with the EXT headset cup, required for running a 27.5” front wheel, but is sold separately for those buying a complete bike. ![]() One frame does it all and can quickly be converted to run 29-inch front and back, Mullet (mixed) or full 27.5-inch wheels. The benefit to end users? A more affordable bike and frameset for downhillers looking to spend more on riding than buying.ĪDJUSTABLE WHEEL SIZE – With so many riders wanting different things out of their bikes, the new Trek Session aims to please everyone from clock-chasing DH racers to Red Bull Rampage hopefuls and park rats. The material and suspension design work in unison to give a very calming and settled feel. Another benefit that riders like Reece Wilson and Charlie Harrison appreciated out of the new Session frame is a muted feel. Major benefits included a slightly more composed bike due to a little bit more weight, a more comfortable feel and a nice snappy feel out of hard corners and big G-inducing berms. Trek engineer Dylan Howes said that the athlete feedback on the benefits of the aluminum frame caused a major reworking of the Session project as the plan had been to move to carbon after initial testing was complete. Both settings offer more progression than the preceding Trek Session but make this bike ready for even more aggressive riding and just about any rear shock you can find.Īluminum Only – In a move that stunned the development team and engineers, all the athletes involved proclaimed that they were so pleased with that initial aluminum prototype, they did not want a carbon version. Wanting to add the benefits and tunability to the general public, the shock Mino Chip takes the bike from 20% to 25%. The idler pulley isolates the chain growth and by reducing pedal kickback, the rider can be stronger, longer and enjoy a more sensitive and composed bike that rolls over obstacles faster.Īdjustable Leverage Ratio – In previous years Trek Factory Racing athletes benefitted from having the race shop make them custom links for different tracks and rider preference. The 2018 Trek Session had 15-27 degrees of pedal kickback depending on the scenario, and the 2022 Trek Session reduces that to 5-8 degrees. This wears the rider out and stiffens up the rear end because of counteracting forces. The cranks want to back-pedal as the wheel moves through the travel, which forces your leg muscles and feet to push back against the pedals to keep them even while standing on the pedals. What that translates to on the trail is pedal kickback and decreased sensitivity of the rear shock. Those weak links are your feet/legs and the suspension. Since a chain cannot stretch, that energy gets transferred to the next weakest link. As the rear wheel moves up and back it moves further away from the bottom bracket. To combat the chain growth from the lengthening wheelbase of a high pivot bike the idler pulley becomes a crucial component. Now, if you are a realist, you will know that nothing comes for free, and moving a pivot to a location that allows for better impact absorption is certainly going to have a drawback. The goal is to keep the bike feeling smoother, reduce deceleration from square-edge impacts and reduce fatigue to the rider on extended sections of rough terrain. In a sense it is cushioning that impact or obstacle more than just relying on a straight vertical path and shock damping. By letting the wheel move in a larger arc, it gives the rear end more time to react and get out of the way. As you move the pivot that the wheel moves around higher, it allows the wheel to move rearward and upward as it encounters obstacles. ![]()
