Trek were very good, prior to collection they swapped some items to XT, ie original spec, and traded the cranks for invisframe. Talk to them, I expect you'll find them accommodating to retain the sale
You've missed the original SL from the list - Specialised Levo SL. I'm selling a Large 2020 model in excellent condition if u are interested, and based in Sussex so not far from u (hope this doesn't break any EMTB rules)
