Chainring adaptors Bombshell

These special chainring adapter bolts replace the standard chainring bolts and allow the chainring to be fitted from the inside of the crankset. This makes it possible to adjust the position or mounting of the chainring. You can therefore perfectly adjust the chainline to be more central, depending on your needs. They are designed specifically to secure the chainring, so no additional spacers are required. This recessed design blends in with the chainring and cranks.

The set contains 4 adapters. The thread recess depth is 5.8 mm. The outer diameter (body) is 9.8 mm. The inner diameter is 7.2 mm.
