yo to all, right, crack is firstly, although i bought my ribos second hand they were in mint condition............ after about a month of pretty solid riding they began to show a bit of wear and tear, the side 'ankle protection' had become ripped and come off due to some unkown reason, ahem , so i came up with a bodge after multiple ankle cuts and gashes, so i got some old footy shin pads with the ankle bit and cut it off, the simply put this on underneath your socks and the put on the ribos, there you have your home made improved ribos. Job done go and admire your handywork and let others dwell in your amazing creativity hope this helped ...........also can you get replacement rachet bits?
