Rennen has taken one of the most simplistic components on the bike and found a way to make it even better. The Infinity line of chainring bolts saves weight with its aluminum construction and features a shoulder on the bolt head to better distribute load increasing overall strength.

The infinity chainring bolts are significantly lighter and stronger than standard bolts making them the clear choice for top-level racers.
