As for the 'side-saddle' problem, that will correct itself with time. are you holding onto your saddle with the same hand all the time? if so, switch, and try to favour the other hand as this will even out any muscle imbalances. Other factors include tyre pressure and road camber, which both make things worse.
How do I get on the mailing list for the news letter? Also I have a question about riding. I am kind of new to uni riding but have been doing a lot of miles on my 36" nimbus. Sometimes it feels as if I am almost sitting side saddle. I suppose I am tacking into the wind and I am trying not to let it bother me but it is quite uncomfortable.Any suigestions?
