The other problem is that the bottle cage mounts have pulled out the frame, should have raised that with On-one but didn’t.
Mud clearance is fine for normal riding, but in the few Cross races I have entered, I have had to stop and scoop the mud out with my hands, I don’t remember them being particularly muddy courses.
My previous bike was a Cotic X which had lovely big clearances.
The other problem I had was the front wheel trying to pull out when braking, had a Tune front hub and skewer, but replaced the skewer with a more substantial FSA one last night, and it seemed better.
