I phoned orange and they told me a triple works..but nothing bigger than a 32 middle ring.
The pro comes with a triple chain set..22/32/42
Had a triple on mine and got sick of dropping the chain, reckon you’ll end up going 1×10 or 2×10 with some sort of chain device.
Orange are wrong!
I know of two people running 24/36 on a triple, I’m sure they can’t be the only ones, there have been some clearance issues when running a 36t in the past, however, for them to say it doesn’t work is just wrong.
Advice should have been, we’re not sure as tolerances vary, try it and see, it may well do.
