Chainring bolt is a small object, but we want to make a difference. ZTTO chainring bolts are the best chainring bolts you can find in this price.
COMPATIBLE WITH SINGLE OR DOUBLE CHAINRING.
These are 5mm and 7mm long, so they work perfectly with any bolt on single or multiple chainring that does not have threaded standoffs.
