Beeing stuck for some time in old skool xc bikes, i am slowly realise some stuff about modern trail/fr/dh bikes. They all seem much smaller in comparison with an xc bike and even smaller in comparison with an old skool xc/dh bike (1992).
Given my old (stuck) ideas , i bought a year ago a 110mm stem (RF Deus). I had a rockhopper large frame (tt 590mm) and the bike felt large to me, with no standover clearance at all.
Recently i got an SX (med, 585mm tt but seems longer since the seattube angle is much slacker). The bike feels perfect as far as standover goes. It is ok with the current (110mm) stem, but usually i feel like i am about to go over the bars, ie i cant move backwards a lot. Some people told me to try an 80 or 70mm stem and 2" risers so that i ll have more manouverability on the bike on steep/technical terrain. Initially this sounded absurd to me since i was used to xc sizes (silly me), but now i come closer to realising that one needs a relatively smaller bike in order to tackle technical DH.
My impression is that a shorter stem will just get me on a more upright position, and not cramped (since my knees are far from my bent elbows). So far i tried to hold the bars with my fingertips, trying to imitate a shorter stem, and it felt fine. (Having the option of trying a shorter stem on loan is not easy here).
Anyhow, i am 185cm tall with a normal build (torso.legs.arms) that is 6.1".
BTW i am ditching the thomson seatpost for a titec
