We designed these bolts to be the best on the market. These optimized single chainring bolts have a 4 mm hex socket on the bolt and a 6mm hex socket on the nut...that's right, no more spanner for your Single Ring bolts! These are 6 mm long so they work perfectly with any bolt on single chainring that does not have threaded standoffs.
