Problemsolvers[/url]do a mismatch clamp which will mate Shimano to Sram.
But if the brakes are i spec B the mismatch clamp isn’t quite out. Will be released mid Feb.
If i spec A brakes the clamp on the web site will work.
They have a UK distributor cant quite remember who but email them they are very helpful.
Im waiting on the new clamps myself.
