ROCK SHOX suspension fork 29 "SID Ultimate SA DebonAir 120 mm BOOST 44 mm offset TwistLoc tapered black | 2021
In order to meet the requirements of modern XC bikes, the SID is now also available with a new, stiff 35 mm chassis, the new Charger Race Day damping with lockout and a DebonAir air spring that is specially tailored to the intended use and has a higher travel in every situation . With the fork, RockShox offers you a race-ready package with extremely low-friction SKF wiper seals and the Maxima Plush Damping Fluid for long-lasting, perfect function and a reduced noise level of your damping.
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 with one valve at a time. Which significantly simplifies the setting of the personal set-up.
It's ok to be soft. DebonAir technology has an extremely low breakaway torque in order to work as sensitively as possible right from the start. The first third of the spring travel is designed to be particularly soft so that the rest can then be used as linearly as possible and swallow small blows perfectly even in the middle travel range. A late onset end progression reliably prevents breakdowns. All of this together creates more traction and perfect control.
Charger Race Day
The further development of the acclaimed Charger damper - the most advanced RockShox technology to date - raises its performance and sophistication to a completely new level of performance. The rebound is individually adjustable and the fork can be locked with the compression. The Charger Race Day is the lightest damping cartridge ever built by RockShox.
For a long time it was difficult to find a suitable place for the remote control of your spring elements. Either it didn't look really good, it wasn't ergonomic, or it even had both of these disadvantages. With the TwistLoc from Rock Shox, the Californians now offer you a lever that looks good, is ergonomic and requires little manual effort to use.
Allows individual adjustment of the air chamber size. This enables you to perfectly match the spring characteristic of your fork to your driving stick.
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 some weight on the unsprung mass.
An axle type with 110 mm width and 15 mm thru axle. The 10 mm wider hub body allows flatter spoke angles and thus enables a more stable and stiffer wheel.
In order to improve the rigidity and the steering precision of the overall system, the dropouts have been enlarged for the use of end caps with a diameter of 31 mm. Use with normal end caps is no problem.
