RockShox | 2027 SID Ultimate 3P | 120mm Remote

Full control without taking your hands off the bars.

The 2027 RockShox SID Ultimate 3P Remote is a 120mm suspension fork designed for modern cross-country riders who want race-level efficiency with the stiffness and control needed for more aggressive terrain.

Compared with the lighter 100mm SID SL Ultimate, this SID Ultimate uses a more substantial 35mm chassis and longer 120mm travel for greater steering precision, impact control, and confidence through technical sections. Its higher-volume 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 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. Unlike the Crown Adjust version, the three compression positions cannot be selected directly from the fork crown.

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.

Key Features

• Remote-Operated 3P Control
Open, Pedal, and Lock settings can be selected from the handlebar using a compatible three-position remote.

• Charger Race Day 2 Damper
RockShox’s lightweight race damper provides a plush Open position, an efficient Pedal setting, and a firm Lock position.

• Lightweight 35mm Chassis
Tapered-wall aluminum upper tubes provide the stiffness and steering precision required for modern XC racing and technical terrain.

• Higher-Volume DebonAir+ Spring
Improves small-bump sensitivity while providing greater mid-stroke support and a more tunable ride.

• Refined Bushing Package
Increased bushing overlap reduces friction and creates a smoother, more stable feel throughout the fork’s travel.

• Race-Ready Construction
A machined forged-aluminum crown, magnesium lower legs, Fast Black upper tubes, and Maxima Plush Dynamic Suspension Lube balance low weight with consistent performance.
