Jtek 1/2 Moon Washer - Rear - Each

I recommend this product

Another vital spare that LBSs don't carry, but SJS continue to provide, almost as a public service. Heartfelt thankyou to Robin and all concerned.
FYI these are steel, well plated and are going to last. I use them on a 1949 Claud Butler with a plain drilled 3/8" brake bridge and Mafac centrepulls with Mathauser blocks. So they're under a bit of strain at times. The bridge is well supported and I'm more confident with these than I would be with alloy or nylon equivalents. All for 99p. Top marks.
