Anyone use these with a carbon frame? Bit worried about the clamping. I’ve seen a side arm 594XT which looks perfect but can’t seem to locate one in the UK.

Also, is the 591 ok with 29ers?

I have used my Carbon 456 on a 591 numerous times over the last year and have not incurred any issues. The clamp is not too bad in terms of applying pressure on my frame and I usually put some inner-tube around the frame.

No problems either. Tighten the clamp to hold the frame not crush it. I normally use some pipe insulation regardless of frame material for extra protection.

i stick my carbon frame in my 591 and drive to Wales or the lakes from Bury all the time. never had any bother, never used any further protection either. ffs its built for hoying down rocky mountains

Thanks for the replies, but just found out my nee car comes with a tow ball so going to go down that route instead.

Get a 561 instead.

591 works fine with my flimsy carbon road bike
