Carbon fibre front triangle and aluminum rear end, with a Rockshox Super Deluxe R rear shock (160mm travel). I’ve owned the bike from new since 2018, and recently stripped it down to use the parts to build up another bike. The frame is in excellent condition and has served me well over the last 5 years. Frame size is XL (I’m 6ft 4 and this fitted me well). Also includes a nearly new Shimano XT press fit bottom bracket which was fitted by Leisure Lakes Bikes in October last year (2022), a BOOST 148x12mm rear axle, and headset (with new lower bearing). Collection only from Manchester or can deliver locally for a small cost to cover fuel. Any questions please just ask!
