I can’t speak for the other bikes but can heartily recommend the T130. With some suspension upgrades (I have modded Fox 36’s and a custom tuned Monarch Plus on mine) I never really feel under-biked, despite having raced it at Tweedlove and Ard Rock this year (beating 90% in my cat as well!). It has handled big Peaks and Lakes rides comfortably and most importantly is great fun on my favourite steep, twisty, loamy trails. I even managed 8 pedal up laps of BPW on it a couple of months back taking in all the black descents back down… The original frame bearings also lasted 2 years due to all the extra shielding they have.
Best of all, it encourages general hooning and you spend most of the time riding it like a snowboard, looking for anything to ramp off on the trail, something other bikes don’t always do for me.
It isn’t 100% perfect, i’d like a steeper seat angle, a slightly lower BB and maybe longer chainstays to make the handling a bit more balanced. Also, shock options are limited on the carbon model.
I would like to get some time on an S150, certainly would be faster, but will it be as much fun?
