Product details


ROCKSHOX suspension fork 29 "SID SL Ultimate SA DebonAir 100 mm BOOST 44 mm offset tapered black | 2021

If you are looking for minimum weight with maximum performance, RockShox has an interesting new fork in its range for you.
The SID SL Ultimate has been completely redesigned and now has a new, light and stiff 32 mm chassis, a newly designed fork crown and the new Charger Race Day damper with Maxima Plush Damping Fluid, which not only improves the function but also the noise level Your fork reduced. The DebonAir air spring was tailored to the special requirements of the XC / Marathon to ensure a safe driving experience in every situation.
The new, optimized SKF wiper seals reduce friction and thus improve the response behavior and the service life of your new SID.

The new SID is lighter, stiffer and more powerful than ever and gets you to your destination faster.


The negative and positive air chambers are only filled at the same time by means of one valve. Which makes it much easier to adjust your personal set-up.

It's ok to be soft. The DebonAir technology has an extremely low breakaway torque in order to work as sensitively as possible from the start. The first third of the spring travel is designed to be particularly soft in order to be able to use the rest as linearly as possible and to swallow small bumps perfectly even in the middle spring travel range. A late onset of end progression reliably prevents breakdowns. All of this together creates more traction and perfect control.

Charger Race Day
The further development of the highly acclaimed Charger damper - the most advanced RockShox technology to date - raises its performance and sophistication to a completely new level of performance. The rebound stage is individually adjustable and the fork can be locked with the compression stage. The Charger Race Day is the lightest damping cartridge RockShox has ever built.

Bottomless tokens
Allows individual adjustment of the air chamber size. This enables you to adapt the spring characteristics of your fork perfectly to your riding style.

Maxle Stealth

Very light thru axle which can be mounted and removed with a 6 mm hexagon socket. In addition to a clean look, it also saves a little weight on the unsprung mass.

An axle type with a width of 110 mm and a 15 mm thru axle. The hub body, which has been widened by 10 mm, allows flatter spoke angles and thus enables a more stable and stiffer wheel.

Torque Caps
To improve the rigidity and steering precision of the entire system, the dropouts have been enlarged for the use of end caps with a 31 mm diameter. Use with normal end caps is possible without any problems.
