You are correct about the limits, but it is wear not stretch. Actually they say it is better to replace when it gets over 1/16 then you don't have to replace the sprocket cluster. When you get out to 1/8" then both have to be changed. It isn't a hard job, especially with the cassette clusters. Cleaning and lubricating the chain frequently will delay the wear. I have over 6000 miles on my SunTour and it is still less than 1/16" Cy Galley - www.qcbc.org Webmaster TC - Chair, Emergency Aircraft Repair, Oshkosh ----- Original Message ----- From: "Steve and Sue Bullock" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, August 01, 2001 1:34 PM Subject: RE: Bicycle stuff Probably the chain. As the chain stretches it wears the teeth on the hub. Mixing a worn hub with a new chain or visa-versa can cause it to slip. Try replacing the chain. A chain should be periodically checked with a ruler for stretch and replaced in good time. If I recall correctly the stretch limit is about 1/8" in a foot. I.e.. about a rivets width. Unfortunately I've mislaid my maintenance book so I can't check this.

I changed rear hub on a couple of family bikes. Now the chain slips. What does this?
