Lightweight XC performance with remote option.
The RockShox SID SL in the 29" version with 100 mm travel is purpose-built for fast cross-country riding: lightweight, stiff enough for aggressive steering maneuvers, and equipped with a sensitive DebonAir air spring for maximum forward momentum over root carpets and during fast race laps.
Inside, the Rush RL rear shock features external rebound adjustment and a 2-position remote lockout (open/lock). With an optional TwistLoc or OneLoc remote (not included), you can lock out the fork from the handlebar in an instant - ideal for sprints, climbs, or smooth asphalt sections.
The 32 mm stanchions with Fast Black finish ensure smooth responsiveness, while the magnesium lowers and hollow-forged aluminum crown keep the weight low. Thanks to the modern Boost axle (15x110 mm), tapered steerer, and Postmount disc brake mount, the SID SL is a perfect fit for modern XC and marathon frames.
With up to 195 psi maximum pressure, the DebonAir air spring can be tuned to suit a wide range of rider weights. The fork is E-MTB certified (up to 150 kg system weight) and allows brake rotors up to 200 mm - providing ample reserves for technical descents during races.
Highlights:
- Race-oriented XC fork: 100 mm travel, 29" wheel size, lightweight and efficient for cross-country and marathon riding.
- DebonAir air spring: sensitive initial response, supportive through the mid-stroke - for traction uphill and control downhill.
- Rush RL rear shock: external rebound adjustment, 2-position remote lockout (open/lock) for optimum efficiency during races.
- Boost standard: 15x110 mm thru axle with Maxle Stealth for high stiffness and easy wheel installation.
- E-Bike Approved: approved for up to 150 kg system weight, also ideal for lightweight e-MTB/XC setups.
