Finally got someone to respond to me on CL. Thanks for all the recommendations you guys gave me. Decided to start small and build up from here if I have any time. 2016 Trek Marlin 5. 29” wheels on a 17.5” frame. Guy said he has only ridden it a few times over the years. The condition of the grips and seat lead me to believe him. No dust in the nooks and crannies either. Need to grab a helmet and I’ll be gtg. Anyone have any experience with the Bontrager Quantum MIPS?
