Ultra compact yet ultra reliable. Will work with frames that have the S3 Low Direct Mount standard - usually some mounting bolts on the seattube or chainstay - but check with your bike brand first. Can be flipped up for chainring removal and has a co-molded soft rubber to your bike even more quieter. Polycarbonate will not break down or go brittle with lube or degreasers
