Excesssive wear on chain ring !!!

[Trek Ferreira]

I fitted an Ultegra 50 / 34 chainring onto my brand new bike and after 2000km of riding the 50 ring looks like a set of sharp sharks teeth. It still works fine but am a little concerned that it will need replacing soon. I am not a particularly agressive rider and thought that ultegra would be more durable. Any sugestions or anyone had a similar situation - or your thoughts in general.

Do you measure and replace your chain regularly?

The same situation here, maybe I am slightly hypercritical had somebody looking at it and it appears as if it was made that way, chain is still original and appears to be within wear specs

very simple... when you replace your chain rings, also replace you chain a cassette. they all wear at the same time, so putting only a new blade on on old chain and casette will result in very quick wear

that is not necissarily true if you replace your chain often enough your rinds and sprockets can and will last a lot longer than reccomended

 

 

 

i replace my chain every 1500km and so far out of my 105 cassette i have round about 10 000km on it my chainrings are slightly shorter at round about 7500km but all in all my parts have lasted me a hell of a long time with no skipping and no jumping on my cassette and dhifting is still perfect

Sheez I thought I was being proactive replacing the chain on my drivetrain after about 15000km...Dura Ace. Blades and cassette are still schweet, hundreds, bru, as well.....I can'tt see how it could ever be necessary to change the buggers so often. If in doubt, head to the LBSand have them measure the chain with that wear gadget goodie they have. Just make sure they're not the skanky ones who will say replace the lot regardless of the condition....

I know its different but my middle XT chainrig lasted 4 WEEKS !!!

[intern]

Flippen heck you must have been punishing that bad boy like nothing else!! My XTR blades have been on the MTB for a year now including 1x Epic and lots of other racing....XT's supposed to last longer??

[123qwer]

I know, it had a new chain and everything 

[turtlek]

i race and train hard and i keep all the other chains for my other projects (dads and sisters bikes) seeing as they wont be ridden as hard as mine but so far no complaints

 

 

 

also thought i would share this but team CSC replaces chains every two weeks on thier bikes and they still have parts on thier bikes(chainrings and cassettes) that are well over 5 years old with over 40 000km on them still in use every day

4 Weeks? You ride in a mud bath? How do you clean your chain?

[123qwer]

With citrus degraeser and a tooth brush, I use squirt a couple of time a week too.

Not so quick with dubious advice please. This topic has been discussed here in depth on several occasions and I suggest you search and swot before handing out advice like this above.

Team CSC has more money than brains. Don't think professional teams necessarilly have the best component maintenance strategies. There's too much free supplies floating around there for them to be sensible.

 

If you guys don't understand how chains and sprockets work and wear, research it. We've discussed it here numerous times.  ADMin - WHERE IS THAT DARN FAQ WE NEED?

 

E-mail me and I'll send you my dissertation on chains and sprockets.

No bru, that's *** advice. Chain wear gadget goodies are inconsistent and most bike shops don't have a clue how to measure chain wear. Not so schweeet advice.

Johan: make a FAQ and I'll sticky it for you, else pm me for suggestions and I'll see what I can do (including phoning Admin)
