Is a Shimano Ultegra Triple Chainset 9 or 10spd?

Have found a very well priced chainset but worried it wont be compatable with my current tiagra 9spd setup. It has 30,39,52 chainrings if this is relevant.

I have checked and it doesnt state 9 or 10spd.

Any help appreciated

    Current Ultegra is generally 10speed, however it depends. the 6500 rear mech and cassette are 9 speed, the 6600/6700 are 10 speed.

    Tiagra 4500 is 9 speed, but the 4600 series is 10 speed... many 2011 & 2012 bikes with Tiagra are 10speed now.

    Although not definative, the 52/39/30 suggests a Ultegra 6600 chainset (as the 6500 chainset is only 52/42/30) so likely this is a 10speed set.

    Also be careful its the same BB setup - some are compatible through the Tiagra/105/Ultegra range and some are not.

    Does it give a model number?

    65xx series was 9-speed, 66xx and the current 67xx series are 10-speed.

    Don't know if you can successfully run a 9-speed chain on 10-speed chainset, but it may well work.

    Shimano Tech Docs is a good source of info.
  • Thats the thing, it doesnt give a model number :-(

    Hmmm, would it be incompatable if it were 10spd againsy my 9spd set up

    As OptimisticBiker says, Ultegra 6503 was 52 / 42 / 30T, so it's "definitely" a 10-speed chainset. Probably 6603 if it's "very well priced".

    Officially it's not compatible. Does anyone have experience of running a 9-speed chain on a 10-speed chainset?

    You can run any width chain with the chainset. Chainsets are not speed-specific.

    they are the same. I run 8 speed with 105 5500 double, which is part of a 9 speed groupset.
  • Here it is. Think its a bargain

    Thanks for the help

    6604 chainset including BB for £75. I'd call that a bargain.
  • Yes, a 9sp chain can be used on a 10sp chainset, but not on a 10sp cassette or rear mech. So if its only the chainset you're changing thats fine...

    Assuming the pic is correct (its a stock pic) with the grey finish its a 6604, but could be a 6603 with the silver finish, which is usually cheaper but still £75 is a bargain...

    Mmm..tempted by this just for the spare chainrings and BB alone :)

    I can confirm an Ultegra SL 10 speed front triple works fine with a nine speed rear end (and a tiagra triple front derailleur).
    I ran my bike this way for a few months before I could afford the Ultegra shifters and 10 speed block etc with no issues.

    In fact, just ordered one....10% off too with their code...thanks OP, would have missed it otherwise. :lol:

    Spotted this the other evening and bought 2 of them (either for projects down the line or to eBay at silly prices!)

    Very cheap with the VIP reduction - got 2 for £130 or so!
  • Glad to be of help. I suppose its also a good start to upgrading to 10spd at a later date.

    If I may play Devil's Advocate, why then do manufacturers say that a chainset is 9 or 10 speed if the speed refers to the number of sprockets on the cassette and / or the chain width?

    I'd imagine it's a marketing thing. They're trying to sell the whole group. The only thing that makes cassettes speed-specific, apart from obviously the number of sprockets, is the spacing. Chainring spacing doesn't change.

  • So, to confirm what was written earlier - a straight swap of one of these (nominally 10 speed) Ultegra triple chainsets for my current (nominally 9 speed) 105 chainset wouldn't create any mechanical issues ?
  • nochekmatenochekmate Posts: 3,460
    No it will be absolutely fine!
  • Are these still available?

    Mine is sat in the box looking lovely. I couldnt resist and for the price its cheaper than a set of rings. I am planing on using the ultegra for summer use along with a new chain and cassette. That way when the bad weather comes along again i have an old setup ready to whack back on.
