For 2k you can pretty much build whatever HT you like, go cheap with a Dartmoor Hornet frame for £185 and then adorn it with £800 new Fox 36’s, Hope/Flox-Ex wheelset, Renthal bars, stem and chain ring, XT everything else (11 speed naturally)…. It’d be awesome and light as the Hornet is Alu….but depending on how much of a snob you are the cheap frame may nag away at you?!
….or go crazy with the frame and buy a Curtis for £1000 but then have to budget with the remaining 1k for a lesser fork, probably a Superstar wheelset, likely 2×10 Deore/SLX groupset etc….
I’d do something in the middle, frame by Stanton, Pikes up front, Stan’s/Hope wheels, Funn cockpit (their stems, bars etc are great), XT brakes and 11 speed running gear….sorted…and probably change left over for some uplift days.
