How high does a pivot have to go before it’s a high pivot? According to Dylan Howes, Advanced Concepts Engineer at Trek and also the man behind every single Session there has ever been, once the pivot goes high enough that the use of an idler to change the chain line is needed, then it’s a high pivot design. Looking back to this, Trek asked what was good about those old high pivot bikes and if it was something that they would like to bring to the new Session. Trek’s history already includes bikes with the same suspension ideas dating all the way back to 2003 with the Diesel and 2006 with the Session 10. Some racers had also cottoned on to the competition’s success and also dropped the question about a high pivot design. The origins of the change coming from a mix of looking at the competition in the world of DH race bikes while also looking internally. The second biggest change to the new Session is the switch to a high pivot suspension system. Trek’s racers also tested with added weights placed on the previous Session’s frame in different positions to understand its effects. The aluminum construction of the new bike was also accompanied by a conversation with Trek about aluminum perhaps being the right material choice for them for the demands of downhill. If a racer tells you that they are ready to take a prototype bike directly to race at the highest level, then you know you’re onto something. It's something that Trek is actually full speed on trying to fully understand and quantify, by opening up the Pandora's box that is chassis stiffness. However, that development was halted after the overwhelmingly positive feedback about the aluminum prototype and its ride characteristics that Trek received from those early tests. Alongside this they were indeed working on the development of a carbon fibre composite frame. We’ll go into the high pivot design in a minute, but first we can start with the material.Īs with most frame prototypes in development, Trek did this with aluminum. The two most immediately noticeable changes to the new Session are the suspension system and the frame material. The new Session is available in aluminum only, after an overwhelmingly positive feedback from the racer's feedback from testing early aluminum prototypes.
