ok here is the problem, I have a dmr sts chain tensioner, the bottom peice mounts up but the top hole thats sposed to go on the axle is to small, cause its made for a qr not a solid axle. what should i do?
drill that sucka out, as long as your solid axle is not so large diameter (i.e. 14mm) you will end up with minimal material on the STS
put it in a vice so its safe (you don't want to drill a hole in your hand or leg!) and then clean it up with a steel file before mounting it on the bike
