Connecting Hardware for Grand Cru 50.4 BCD Cranks, Double Kit
A more modern version of connecting hardware for classic 5-pin cranks. Stainless steel nuts and 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.
We recommend using a drop of Locktite on each bolt.
We have a single kit as well.
