Tiagra vs Ultegra chainring

    Hi all,
    I need to replace my cassette/chain/big ring for my commuting racer. Currently on a Tiagra setup, plan on sticking with a cheap HG50 cassette but I'm tempted to upgrade the big ring to Ultegra, particularly since Ultegra chainrings are in fact cheaper than Tiagra on CRC. Is there any difference in longevity with higher spec rings? I'm doing almost 300 km a week so want something that will last me a while.
    Cheers,
    Eoin

    As long as it fits go for the cheaper one, ultegra in this case. Normally the higher up the groupset food chain you go the lighter and sometimes less durable the metal can be. An Ultegra chain ring should last you many thousands of kms though. How come you're changing the big ring only? I would have though this was least used of the two (assuming it a double chainset).

    Are you sure the rings are compatible? You can check it out at Shimano Techdocs.

    Also check prices at Rose and Bike Discount as they're usually very good value for chainrings.

    Lastly, get yourself a chain checker:).

    It's a compact chainset and I'm living in a pretty flat area, so the big ring sees the vast majority of the action. Added to that, my left hand shifter stopped working about a month ago, so I don't have much of a choice now anyway!

    Yep, both are 110 bcd, so shouldn't be any problem there. Would there be any issue running a 9 speed chain on a 10 speed ring? I assume it would only be an issue with a 9 speed ring and 10 speed chain? It turns out Rose is indeed cheaper for the chainrings, thanks for that! I'll definitely be getting a chain wear indicator while I'm at it!

    Difference is thickness, and I think smoothness in shifting.(Don't hold me to that) Probably will work but wont be as smooth shifting.
