Q & A

What crankset would you recommend with this? Looking to pair this with a Sensah Empire 11 speed kevin asked on 28 February 2022

Quite a number of people use a ROTOR type. Seems to work well.

Can use this for the THM Clavicula SE Crankset? Steve asked on 29 January 2022

It may or may not be. If you supply a drawing with the DBCA I will be able to say for sure. The THM has wedge locking system (taper) in one side and can cause problems.

If the DBCA is 90.5mm minimum then yes it would.

admin answered on 7 November 2021 store manager

Can you explain what DBCA is? I've checked manufacturer spec(https://canecreek.com/wp-content/uploads/2019/08/eeWings-All-Road-User-Specification-Rev1.pdf) and I'm not sure which it is refering to.
