Archibald Cycles Pinion T47 Bottom Bracket Carrier

CA$400.00

Our bolt-in bottom bracket carrier replaces a Pinion gearbox with a conventional bottom bracket, allowing you to run a standard crankset for a derailleur drivetrain or singlespeed setup.

The carrier uses a 73mm shell width with T47 threads, giving you plenty of bottom bracket and crank options. On the AC1, it makes switching between gearbox, derailleur and singlespeed setups completely reversible.

When added to an AC1 Frame Kit, we'll supply the appropriate bottom bracket for your build.

Additional Info & Compatibility

The carrier uses the standard six-bolt Pinion gearbox mounting pattern, so it isn't limited to Archibald frames. It can also be installed on other frames designed around the same Pinion gearbox interface.

If you're installing one on a non-Archibald frame, you'll still need to confirm drivetrain compatibility, chainline and clearances for your particular setup.
