Thinking about getting a '17 trance 2. It seems like the alum models have the 140 fox while the advanced gets the 150 yari. Would upgrading the aluminum models to a 150 later on still work with the geomety? Are they the same frames only difference being the carbon/aluminum? Also, the shock is a evol with "trunion" mount. Anyone know if this is proprietary and would affect a shock upgrade in the future?
Lastly I haven't seen a '17 sizing chart just yet. Anyone know if the sizing stats the same? By the numbers the medium seems larger than most other brands. Same reach as a large stumpjumper!
