Does my ENO hub slip a bit because it has steel axle nuts on an aluminium frame? It doesn’t seem to slip on steel frames. Or did I just not tighten it enough?
Have you set the axle so that it is more rearward and pointing down? So your fat-ass is keeping the tension on the chain. And what are you doing riding an alloy frame? Well Shameful, take the shame.
You’ll be rearward and pointing down in a minute. The axle’s where it is because the chain is only as long as it is. The axle is below and in front of the bolt.
I haven’t had any experience with ENOs, but I would assume that it was the bolt torque, as aluminium is almost always softer than steel, so you should have been able to bite into Al dropouts a bit easier than steel. If you have knurled locknuts of course. If they’re smooth they may slip a bit easier on aluminium.
Why is it slipping? i.e. under torque (acceleration or braking) or from vertical loads?
