Well im finally going to look into some bar ends for my XC rig. The thing is, im using an EC70 handlebar and i know you need to be a little careful when using carbon handlebars with bar ends and whatnot. THe easton site gives some examples of bar ends which should not be used. One of them is Ritchey, which is a shame since I was looking at the WCS Ritchey bar ends. When they say ritchey though, do they mean all bar ends by Ritchey should not be used? Or would I be okay with WCS?
