R&G tail tidy is not ment to be bent all the time (or at all for that matter). Any metal can withstand only certain ammount of "bents" or "adjustments" if you will. If you're looking for an adjustable tailtidy, there are brands made specifically for that purpose - "gunning it" or "running toll booths"
I have R&G tail tidy on mine and can not say anything bad about it.
The only negative thing I have to say about R&G it's that their CS doesn't reply to emails, at all! Other then that, their products are high quality ones and pretty durable. Have lots of R&G staff on my bike, so I know.
