Best rim ive had was probs my onza ronnie rim , ive tryed , 2 try alls , 1 echo , 1 monty. The ronnie kept straight , just slightly weaker sidewall but i thought
this was good as it protected it from cracking / flatspot. Echo , probs next after that , then tryall i didnt really rate that rim i kept having to get the spoke key out
all the time , good build aswell. Then monty , lol.
downside of ronnie rim which you mite not like - its quite thin.
