United Kingdom - 10 speed and 9 mixing ?

I have been wondering if i can upgrade my dura ace tri bike to 10 speed by changing cassette, chain and rear shifter ? Will the narrow chain sit on the dual chainrings ? If not it will be almost a groupset to change and I am not sure I want the 10 speed quite that much
Have seen some reasonably priced carbon wheels on E bay, but are 10 speed only, hence the thoughts. Ian

Presumably you have 9 speed stuff now.
If that is the case, the chain will behave fine on the new chainrings as there really is very little difference between the spacing of so-called "9-speed" and "10-speed" chainrings. 0.6mm springs to mind but that may well be a lie.
Anyway, in answer to your question, you should be fine. In future, you might want to post such questions on the mechanics forum to get more / more rapid responses. :)

think the internal width of the 9 and 10 speed chains are the same, the only difference is that a 10 speed chain has narrower link plates?
if you have 10 at the back, you will probably a matching chain.....
Yes, the thin links would make sense, they would also contribute to chain stretch/wear. Something I see too much of already on my mountain bikes!
I will look into some good s/h 10 Speed shifters and a new cassette and chain.
The left overs should convert my sons 8 speed Tri bike to 9 ! I do know that 8 speed chainrings are a little thicker than 9, but they are a few years old , so should be fine!........... Thanks

i run a mirage 8 chainset - i think it's from just after the range was introduced, and i run a 9 speed chain, with 8 speed cassette......so you should be ok

You know chainrings are the things that are bolted to your crank, right?

I'm not sure but the guy said he was getting a new chain anyway. The question was whether the new chain (10s) would behave normally on the old (presumed 9s) chainset / chainrings. It seemed like you were suggesting that he should think about getting a new chain based on the cassette block at the back.
