Can anyone tell me what the major differences are between the s and the r. Would I be right in thinking that the r is more track focussed. I've been offered an r but I don't want to be bounced out of the seat every time I go over a catseye!!5 m

Is the s more road focussed? Sorry to ask questions and not make any contribution but that will def. change soon.
Thanks for any help volunteered.
Mike
