I got a MTB style shifter/brake lever with an aluminum bar clamp (22.2mm?). I pried the gap apart until I could fit it over a moustache bar (24mm OD). I know that aluminum doesn't bend happily. I also know that aluminum is prone to stress cracking and catastrophic failure.
My question is "How safe is this?" The extra 8% stretch that the clamp had to do hasn't visibly caused any cracking or other stress. Provided that the clamp is inspected before each ride, should it be reasonably sound, or is undetected stress cracking likely?
I like the ergonomics of the adaptation, but don't want to risk my life if the darned thing breaks unexpectedly (particularly under heavy braking). Opinions? Thanks.
