Which Shimano chains are these? I'm interested.
Shimano HG-53 9-speed chain. I bought several on sale at Nashbar last year. Think I paid $9.99. Nashbar currently has the HG-73 chain on sale for $12.99 and you can get 10% off that with Coupon Code TKA6.
I read the recent discussion here about checking chain wear and I tried several methods to check my Campy 10 speed chain. Campy states in their instructions the the maximum lenght for six links is 132.6 mm. My chain has about 2700 miles on it and it measured about 132.5 using accurate calipers. If I measure 12 inches using a straight edge, the chain shows hardly any wear. It is bearly 12 1/32". So, I really don't know if my chain needs to be replaced or not. Which method should I use? The chain is not making any excessive noise and the shifting is perfect.
In my opinion, the chain is still OK to keep in service, but it is showing enough wear to merit checking on a regular basis. The fact that it still shifts OK is not an indicator of suitablility for continued use; many worn-out chains will still shift well. The important thing is to replace it before the chain's wear starts to increase the rate of wear of the sprockets. -- Typoes are a feature, not a bug. Some gardening required to reply via email.
