Thinking £1200 is a reasonable asking price, but it's hard to tell without seeing others in similar condition/spec. Not in a rush to sell, but would rather avoid the bunfight of Gumtree/eBay/Facebook marketplace if at all possible. Would prefer not have to courier, but if you're keen I'm sure we could work something out.
I've owned it from new and it's in good condition and been well looked after, but inevitably with a bike like this there are dings, scratches and scuffs that show it's been used. They're all aesthetic though, and it's mechanically sound. I've just done a full service on the fork (air spring, damper and lowers) using genuine a Rockshox kit.
Still a great enduro bike. Burly alloy frame. Modern geometry but not stupidly long/low/slack. Pro version with lock-out fork/shock for more efficient climbing. Might not be the ideal bikepacking bike, but I did the Lakeland 200 on it.
