Rather than fit a replacement road chainset (50/34T), I’m tempted to move across the XT M780 crank from my MTB.

Assuming I can fit 104 BCD rings – e.g. 48T outer – am I missing any no-go issues?

I’d be using a 105 5700 front shifter and mech, fitted to a Cotic Escapade with a 68mm BB shell.

Thanks 🙂

Nasty chainline – you’ll need an MTB front mech – the 105 won’t reach far enough unless you modify it. It’ll fit though.

Thanks. I do happen to have an XT M770 front mech lying around, if that would work?

No probs done it on mine 10 speec double that is, spin out at 25 mph running a standard road mech super low climbing gear it’s just silly.

Yep, as long as the fitting is right an M770 mech will work.
