A more modern version of connecting hardware for classic 5-pin cranks. Stainless steel nuts, bolts and alloy spacers. The huge improvement is the use of 5mm allen head fasteners instead of a tiny 8mm bolt and nut. No more skinned knuckles and stripped bolt heads.

This kit is enough for one complete double crank arm set. There are six bolts/nuts/washers to connect the inner chain ring to the outer chain ring; there are five bolts/nuts to connect the outer ring to the crank arm. Compatible with Grand Cru, TA, Stronglight, and most other 50.4 BCD cranks.
