is there that much of a difference in performance between a Fox RP23 to the RP2?
is the extra 3 worth the extra cash?
and the same goes for XT to SLX is there that much of a difference in performance between these two? (ignoring the brakes)
would going for XT / RP23 justify an extra £500? (difference between two models kitted out with the above)
any opinions / experience on using the above? help appreciated.
