Any tips to stop going through so many rear wheels?? I've rode maybe 200 miles on my bike so far and have gone through three rear wheels already. Bent rim and loose spokes. I'm only 155lbs and don't have any luggage weight on the rear and only do city road riding. I'm thinking of investing in a set of Gemini wheels but don't want to spend all of the money if they're just going to get bent up like these past wheels.
