There was'nt anything wronge with Johns setup, he just does'nt like the feel of having the weight at the back.
He should have had a much better result at the EOE regional, he did'nt feel like he could push how he wanted.
Turn it into an X6 mate, or get a RB5 and put 'The colesie' setup on it!
I've meet a few people now who can't get on with the feel of the B4, I can't understand way, but with some of the RB5s, CRs, X6s i've seen I think at club and regional level theirs alot of choice.
The RB5 at our club is really good!, after this guy (Colesie) got the AC bits and had a fiddle with a few things. it corners faster and floats over bumps!
Plus someone running in the EoE regionals has a RB5 thats going very well!
