Question – Rockshox SID B (2014) has travel from 80, 100 and 120mm. My Epic with Specialized Brain is 100mm. Can I upgrade this to 120mm?
Short answer – No
Long answer – No, the Brain Cartridge connects the fork Upper and Lower sections and has 112mm of travel at best and really only 107mm usable.
If you get rid of the Brain damper and buy the parts to convert it to an RL, RLT or RCT3 damper, the the uppers and lowers are seperate.
Also – if you are wondering how to disassemble your lowers, you need a 10mm box wrench. No shortcuts.
