I'm still a bit uncomfortable on my bike... and feel as if my elbows are lifted too much when on the bike... I also frequently notice that my shoulders are tensed up... I consiously release them ... only for them to go back to the previous state. I have been getting a bit of back ache too. My current bars are almost flat - a small rise in them. My wrists also seem to be pointing out (ish). (There is a chance this bike is too big for me - but the size smaller definately felt too small). What I was wondering is do I just need to change the stem to make the bars higher or change the type of handlebars? I had wondered about those ones that curve slightly backwards towards the rider? (But not enormous possy ones that would get in the way when trying to filter). I'll try and get a photo later to illustrate what I mean, but which should I change first to try and improve my comfort?
