mine has thinner wheels, and no i have not replaced any cables on the bike.
i did come across on those bar end add ons on amazon, they do look pretty good with tape added. the add ons are my plan b . to add the bar ends i would have to buy a flat bar and the add ons correct ? do you think i will need a different neck ?
