I picked up the Bonty one from my local shop at the weekend for my Giant post. It looks basicish – forged rather than machined lever – but it also seems pretty nicely made. I’d love a wolf tooth one, but need new tyres at the moment as well.
I imagine you could make it work with the other way round (ie clamp at the post end) by just cutting the head off. If the lever on my Brand X on the other bike fails and the bounty works out well, it’s probably what I’ll do.
The Bontrager also comes with a cable and a barrel that the cable head fits into. I’ll check if it fits the actuator on my Brand X next time I pull it out of the bike.
