Ended up a busy day in the end ,decided to strip the di2 kit off the turbo bike and ended up virtually re-building it so CX chainset and 36t chainring on and old Altus rear mech to act as a tensioner; had to rig up an old shifter to hold the mech in place as I couldn't get a decent chainline with the limit screws and the setting on the cog.All ok now though but decided to leave a trial run until it's a bit cooler.
Now have a complete Ultegra Di2 gear set spare although still need to get some old shifters as the Ultegra ones are still on the bike.
Instead I then thought I'd see what the 650 Stayer/Rene Herse wheels would play with the Stayer All-Road; I had run the wheels briefly before but had much knobblier/heavier tyres on. Front was fine but needed some 'persuasion' of the rear mudguard to give enough clearance and not look too weird, sorted now so will give it a spin poss tomorrow morning or evening.
