I bought a new bike with sram guides and the reverb trigger is directly mounted to the brake lever, I dont like the brakes so was going to swap them with the hopes off another bike, is there an adapter for mounting the reverb to the brake or do I need a new clamp for the reverb?

Also I have a GX shifter and ordered a hbsp 246, does anyone know if thats the right one(says its for xx)

The guide lever mounts to the reverb, not the other way round. No clamp needed.

Yup, reuse the clamp from the Guides, I’m about to do exactly the same, if the as yet to be named bike shop ever find my V4s that I ordered which they ‘know have arrived, we just can’t find them’….

Nice one thanks

You’ll need a clamp for the Guide if you plan to use them on a different bike.
