finally, it appears that you can order a shimano xt-t780 on amazon.co.uk but get a german listing. that may be the simplest way to get it.

however, it's all theoretical as I haven't ever used these parts in combination with a CUBE LTD frame, which may cause an issue.

however, however, VSF has a stellar rep and i guarantee their bikes don't rub in any gear combos.

also, keep me posted.

also, also, it looks like there are two model 63-66 degrees and 66-69 degree.

this is slightly (majorly) beyond me but good luck.
