got a large (long really) one with a Pushed Vanilla coil shock and coil pikes, mine's a mini DH build, DH cranks, MRP, 721s, juicy's and kinda custom DH tyres.. it weighs in at 37lb and at places like innerleithen it's a faster DH bike than my 41lb Sunday. with the pikes (always at 140mm) the BB height is only raised to 12.6", the head angle is a nice DHable 65deg and it has a decently long wheelbase for riding flat out.
Jambo – can empathise with you about riding it at Ft Bill.. even at innerliethen doing full runs at race pace on some tracks can become pretty sore on the feet with just 4". where did your two snap?
