This precisely CNC-machined aluminum preload adjuster includes two threaded rings (29mm and 30mm) to fit a variety of 30mm cranksets and 29mm SRAM DUB spindles. Its design eliminates the need for adhesive or trial and error. Simply choose the appropriate ring for your crankset and slide it on. A specially designed silicone oval ring firmly holds the inner ring during adjustment, allowing you to eliminate play and properly preload your A/C bearings by turning the outer adjuster. Final tightening is achieved with a recessed 2mm hex bolt for a secure fit.
Please note that this adjuster is designed to work with cranksets that do not feature integrated threads on the crankarm. In most cases the integrated threads are not the same pitch or diameter as this adjuster.
