You don’t need a front derailleur but your frame has a S3 front derailleur mount anyway? Just put this cover onto your bike to make it look cleaner! At the same time it protects the derailleur mount and its threads! With a weight of only 2 g and a high quality material, the cover is superlight and strong at the same time. It’s designed for the use of two M5 countersunk Allen® screws such as DIN 7991 – M5 x 16 (or ISO 10642 – M5 x 16). To find out if your front derailleur mount is a S3 type measure the distance between the two holes. The distance between the threads of a S3 Direct Mount is about 22.7mm / 22.1 mm from centre to centre. (Depending on how you measure it exactly)
