RockShox SID SL Ultimate Flight Attendant Fork 29", 110mm, Boost, 44mm Offset, Electric Red
SKU code: PSI-RX004021169000
RockShox’s SID SL is its lightest cross-country race fork, built on a 32mm chassis, and the Ultimate version adds a machined, anodised crown. This one is the 29", 110mm, 44mm-offset build in Electric Red (gloss).
Highlights
- Flight Attendant Race Day electronic damper that switches Open/Pedal/Lock automatically
- DebonAir+ air spring with Bottomless Token tuning
- 32mm chassis with increased bushing overlap and lower friction
- Room for tyres up to 62mm wide
- Boost 15x110 Maxle Stealth, 1.5" tapered steerer
- Electric Red (gloss); ZipTie mudguard included
Flight Attendant
Flight Attendant reads the terrain and your pedalling and moves the damper between Open, Pedal and Lock in real time. RockShox has added a fork-only mode for hardtails and an Auto Mode that can be set to skip Pedal or Lock. Setup and tuning are done in the SRAM AXS app.
Chassis
RockShox increased bushing overlap and reduced friction on the latest SID SL, and made room for bigger tyres. The crown is forged, hollow aluminium; the lowers are magnesium.
Compatibility and fit
Needs a 1.5" tapered head tube, a Boost 110mm front hub and a disc rotor from 160mm to 200mm. Axle-to-crown is 521mm. Not approved for eBike use. Maximum rider-plus-bike weight is 150kg. We recommend workshop fitting so the steerer is cut and the fork set up correctly.
