Yup, Steel rim with 12 guage spokes, I've said it time after time. If ya ride REAL light, ya might get by with an aluminum rim and 14 guage spokes. But a rag joint putting extra stress on what are already a light guage spoke usually works out just like what ya got now. a wobbly wheel. most bike shops will sell you a steel rim with 12 guage for about $50. Then, of course I'm in favor of adapters too. a rag joint will work if set up on a proper wheel. I just don't think a aluminum rim with 14 guage spokes is good enough for that. I have a customer in now that FINALLY,(after 3 bent wheels) went down to Bicycle Express and spent his $50 for a proper wheel. He should be OK now. You might get the aluminum rim with the 14 a little cheaper, but in the long run yer gonna spend more replacing bent wheels.
