I'll be upgrading my Dakota D29 with XX1 soon.
Is there any issues with the 156mm Q-factor?
Will I be limited in Chainring size choices?
I was hoping to use a 34T ring.

Thanks!!!

Carlos,
The 156 Q-factor will not work on the D29 you will need to go with the 168. There should be no issues with the 34t
