Re: The best saddle clamp ?
Is the clamp breaking or just the bolt? You could consider replacing the stock fastener with a better grade of steel. Or, I agree with David. If the seat tube is squished and out of round then that might be your problem. No offence meant but how much do you weigh? This is not really a common problem that we hear much about.
