When we need the highest performing and lightest weight fork for racing, the RockShox SID SL Ultimate 2P Remote 29in Boost Fork is the first that comes to mind. This ultra-light cross-country-specific fork features a TwistLoc system that quickly locks and unlocks our suspension from our hands at the handlebars. This ultralight package comes with 100-110mm of travel supported by the proven Charger Race Day 2 damper, a DebonAir air spring, and lightweight 32mm stanchions. Improvements upon the previous generation included a machined aluminum crown for weight savings and a revised leverage curve, resulting in more efficient use of travel.
