Although he was riding "his" Yaabaa stinger that had 45 BB but I guess long chainstay make it feel lower. I ridden Adamant that had +10 BB rise, GU with +35 (or 40 not sure) by 380, yaabaa stinger 45 by 390. And now riding Slate 2 with 55 and 380. I would say GU and Stinger felt amazing on the back wheel, prety much hopping by themselves and were realy stable! These are frames that helped me progress a lot! I only ridden Slate 2 for 2 days now, but feel there is something about this comp machine, not sure what...Rear wheel hops and gaps are kind of tricky, that must be 4 weeks break, but rolling thing (taps, ups, etc.) and static stuff to front is prety damn comfy.
