RockShox | 2027 SID SL Ultimate 3P | 100mm Remote

Every gram matters when the clock is running.

The 2027 RockShox SID SL Ultimate 3P Remote is a lightweight 100mm suspension fork designed for dedicated cross-country racers chasing maximum efficiency and minimum weight.

Unlike the more aggressive SID Ultimate with its 35mm chassis and 120mm travel, the SID SL Ultimate uses slimmer 32mm upper tubes and shorter 100mm travel to prioritize climbing speed, precise handling, and race-day efficiency. Its DebonAir+ spring improves small-bump sensitivity and mid-stroke support, while the Charger Race Day 2 damper provides Open, Pedal, and Lock compression settings controlled from the handlebar.

Important Compatibility Note

This is the Remote version of the 2027 SID SL Ultimate 3P. A compatible RockShox three-position handlebar remote using 7mm + 7mm cable pull is required to control the Open, Pedal, and Lock settings.

The handlebar remote is sold separately and is not included with the fork.

Designed exclusively for 29-inch wheels, 15 x 110mm Boost front hubs, compatible tapered head tubes and headsets, and disc brakes. This fork is not approved for use on electric bikes.
