Refresh suspension feel with the DebonAir+ Air Shaft for SID SL E1 110mm forks
The DebonAir+ Air Shaft for SID SL E1 is a high-performance replacement designed to restore or modify 110mm travel performance in the latest generation of RockShox SID SL forks. Built to match the 2026+ chassis with 32mm stanchions and 29-inch wheels, this shaft assembly ensures a precise, friction-reducing fit and reestablishes the plush yet supportive feel that defines the DebonAir+ system.
The kit includes the air shaft and bumpers and is ready for easy installation as part of a scheduled rebuild or travel conversion. Riders looking to fine-tune their setup for specific XC race demands or simply maintain peak performance will appreciate how this component reinvigorates fork sensitivity and damping consistency. As a SRAM Original Part, it integrates perfectly with compatible SID SL models and provides a race-ready refresh without excess weight or guesswork.
