Willehond Posted March 22, 2010 Share OK, so I grind the big gear a bit, but my bike is less than a year old and the bike shop just phoned to let me know I need a new 53 blade (and possibly the small chainring too!). How is it possible that it could have worn that much in such a short time? I had no shifting problems! I am slightly suspicious.... Anyone else have this happen to them? SRAM Force ring if anyone is interested. Link to comment Share on other sites More sharing options...
Mudsimus Posted March 22, 2010 Share I think they are taking you for a ride. What about the chain and cassette? Are they replacing those as well? Link to comment Share on other sites More sharing options...
Christopher Brunsdon Posted March 22, 2010 Share Did you run your chain to post 1% wear? Well I know some people live by the gospel that you replace you chains and blades if you ever go over 0.75% chain wear but I would get a 2nd opinion first on that.

kosmonooit Posted March 22, 2010 Share Best go there and ask them to show you why it has to be replaced. Its easy for find some references on the iweb so you go there prepared, and its your call after all.It's the same as every time you take your car in for a service to the agents they want to fit new brake pads. And I got fed up with LBS trying to milk me everytime I took a bike there for a service, perhaps there are some that dont, ?and dont want to generalise but ....

Willehond Posted March 22, 2010 Share I think they are taking you for a ride. What about the chain and cassette? Are they replacing those as well? Yip, cassette and chain too. This I can live with, but the big blade??? Man, on my other bikes I've been running the same blades for years and no problem even though I've mothered countless cassettes. Never trust a bike shop that has 'cheap' service rates. There aint no such thing. Link to comment Share on other sites More sharing options...
leet22 Posted March 22, 2010 Share Could be. How many Ks have you done? what type of riding? clean and Lube your chain after each ride?. Link to comment Share on other sites More sharing options...
Mudsimus Posted March 22, 2010 Share Tell them to leave it as is, and test it yourself. Just replace the chain and cassette. Link to comment Share on other sites More sharing options...
Guest Big H Posted March 22, 2010 Share When in the shop compare the old chainring with a new chainring. Excessive wear will easily be seen. Chainrings can take and handle a lot of wear before chain suck becomes a problem. I think they are trying their luck!!!!!!!

Willehond Posted March 22, 2010 Share Thanks guys, I thought so too. I'll ask them to only replace the chain and cassette. Perfect time though to order the compact crank I want... Link to comment Share on other sites More sharing options...
