Crankset - Oval Ring Fun

Triathlon Forum
1

I’m looking for some guidance and expertise here…

Problem:
I’d like to run a 55/42 oval setup on my Trek Speed Concept with power.

I did some looking and feel switching to GXP with a Quarq DZero crank with Rotor rings is the route I’d like to go. However, I’m not sure whether I need the hidden bolt or non-hidden bolt option from Quarq to work with the Rotor rings.

Anyone have any experience with this setup or willing to share some other ideas?

I used Q-Rings for many years and switched to Absolute Black 2 years ago. Significantly stiffer and shifts better. Just something to consider…

I’m pretty sure you need non-hidden bolt for Rotor. Absolute Black offers a version for each type

i love my absolute black

But i think only osymetric make something in the size you are looking for.
