You could try the semi-metallics as that's what the TRP Spyres Ship with by default. The only real determinant of what to get is the rotors - some shimano rotors have Resin Only on them so you should stick to them if that's the case but otherwise shouldn't be a problem to swap type - you need to clean the rotors but looks like you're doing that anyway.Been looking at Clarks organic vx one's but going to give the disc's a clean first and have a look at the pads as it was meant to have been serviced just before i got it
Just been looking at Noah & Theo but they have no resin pads available to order on e bay shop
What ever i order on line it's doubtful they would arrive before christmas
Thanks for the suggestions
