[Closed] Its a Hardtail life...

Ok so im fair new to the world of hardtails, currently riding an alpine and have a cannondale prophet, wanting to build something that i can have even more fun on! a hardtail... question is what frame do i go for? i want something i can do xc on but also tech stuff like drops,stairs, n bits of downhill, im looking towards the Ragley/on one- kinda frames at the moment, ive seen some good deals on the on-ones but some say only take 120mm travel forks? or 100mm travel? ive been told the 456 is prob going to be the best as it takes a 150 travel ? im wanting to run a 140 really, what frames out there can i go for? and will the on one 456 frame take a 140 fork? Cheers!
