Ok newbie question here but i have covered just over 300 miles on my new bike (specialized tri-cross) since Jan and today when cleaning the bike i noticed the large front chain ring is showing signs of wear to the teeth already. This is very noticeable on about 6 of the teeth. My question is how many miles would you expect a front chain ring to last before showing signs of wear. As 300 miles seems not very much at all to me. I appreciate this would depend on the type of terrain etc i'm riding on. 90% of the rides have been on tarmac roads with 10% on cycle tracks mainly tarmac with a few stretches of compacted gravel.
