Get the t-mag spec 2, its such a good bike i got mine about 3 weeks ago, there so strong and they look the nuts, the disk takes a while to wear in (bout week or so) but after its worn in its so responsive. the tensile cranks are so nice as well but the only down side is that the frame bends a bit at the back due to the maggie, i wud sugest getting a brake booster, i did and my rear brake is well good.
hope i helped ;)
