Cycling road bike brake pads (the type that slide into the metal holders for road bike caliper brakes).
1 pair Fibrax red
1 pair FWE black
2 pairs Aztec Road plus (example in attached image from www)
The FWE were never used, the other pairs were used very briefly but I quickly decided I didn't like them them, went back to my preferred Kool-Stop.
Can split no problem.
Happy to drop them off if you're in/near Shrewsbury or collect from Gains Park.
