According to the specs on Trek's website, my road bike has these handlebars:
Bontrager VR WSD, 31.8mm
Does anyone know what "31.8mm" refers to?
These handlebars are a good size for me in terms of being able to ride comfortably in the drops, but they are too wide. I would like to get the same model in a narrower width. Unfortunately Bontrager does not show any WSD handlebars on their website, and if they don't sell them then I suppose I will have to look for a different brand. Which really sucks, since I have no idea where to begin if I have to find a different brand.
I appreciate any advice on this.
Thanks!!
