I currently have a 90mm stem with 8 degree fall on a 53cm Cube Peloton with (I think) 40-42cm bars. I say I think as I have measured outside to outside, and am not convinced that this is the way these bars are measured. I also have a seatpost with around 10mm of setback and the stem is set fairly high.
Riding with this setup is generally comfortable using the tops of the bars, but after a while my neck and shoulders feel stiff and I find myself shifting forward on the seat, particularly when attacking. I am going to lose some stem spacers and have just obtained a very nice Thomson which is 100mm with a 10 degree fall. And I plan to change the seatpost for an inline one.
I am hoping that this will give more room for my shoulders, and pitch the weight forward. My question is regarding the bars. Given the current width, would I be advised to go for the same again, or wider? On my MTB I use a 720 bar with a 50mm stem and thought that the longer the stem the narrower the bars, is this different on road bikes? I am looking at these as options: http://www.chainreactioncycles.com/Models.aspx?ModelID=92895
Thanks in advance?
