Hi everyone. Just wanted an opinion if you have tried these ergo cable guards on ebay http://cgi.ebay.com/ws/ebayISAPI.dll?viewItem&item=3659800544&category=36140 . I have problems with my cables rubbing on my pinarello's frame and it is starting to have markings on the head tube area. Are there other solutions that you can give me? Seems like the pictures and the theory behind seems to be practical and possibly could work. Your inputs are highly appreciated.
