What kind of pedals are on it? Something you've used before on other mounts?
I'm 'breaking in' a pair of Assioma Duos currently, Look-pattern SPD-SL cleats needing some slight tweaks to cleat position on shoes to eliminate some knee discomfort. So far I've used 'em on my trainer-mounted Tarmac, running 170mm crank arms. I'll be moving them to my gravel bike (alloy Diverge) this afternoon, that has 172.5 Cues cranks. Supposed to warm up & be sunny on Tuesday so I can start back to riding outside again soon!!
