They should be made of a Teflon/Nylon like material and be long wearing and I've heard of people liking them compared to messing with circlips. No chance they'll pop out like a clip either. As for lifespan, it's anyones guess. I've never used them.
Those are called Teflon buttons. We used to use them on the race bike motors we built in the late '70 and early 80's they work fine and I think they'll last but I don't have much experience past one season of racing.
Thanks for the info guys! I ordered a set it'll be off to the machine shop when they come in. The "professionally honed" cylinders I bought are way oversized. More so in the right cylinder too. It smokes like a mother. Once this is done i have a 350 hardtail to put together and I'm getting antsy.
hi,i bought a set of these off e-bay 2 years and almost 9,000 miles ago and have had NO issues what so ever.the ones i bought were .750 oversize or something like that.ring markings for top are hard to read but that was only issue with whole kit.tim
