Chainset Shifter compatibility.

Would there be any problem using Tiagra 9 speed levers with a Tiagra 4700 10 speed chainset? I'm not sure if there is any significant spacing difference between 9 and 10 speed chainrings.

Nope. none. will work fine.

dandl

Thanks very much. That helps a lot.

I haven't had any problems as well

That's good. I want to update my daily hack as it has gained a bit of a mix and match of components over the years. It is basically an 8 speed triple at the moment but having got hold of a new Tiagra 10 speed 50/34 chainset and BB quite cheaply and already having a 9 speed rear mech, I would just need a pair of 9 speed levers, a double front changer and a 9 speed cassette and I could get myself a 9 speed double which would do me just fine. It would be much cheaper than going 10 speed as well.

if you fancy a mad punt you could go Exustar Chinese off the Bay and go full 11 speed for £150

gets alright reviews as well

dandl

Must admit, new one on me but their pedals, shoes and cleats seem to get very good reviews.

Worth a punt?

as above, a few good reviews kicking around and there was some dude who did a whole load of vids about he built up his bike completely from Chinese parts to prove a point and he reckoned it was pretty darn good for the money.

Just a final question connected with my original question. Is the geometry of all Shimano road rear mechs the same with the rear mech steps governed only by the shift lever? I know you wouldn't want to do it but if you used an 11 speed lever with an 8 speed mech, would the rear mech index in 11 speed spacing?

bobones

The cable pull must match between RD and shifter or it won't index properly, and that's changed between older 8-10 speed and newer Tiagra and 11-speed AFAIR.

thars your man - grazie.

i've only flicked through some of his stuff but he seems alright, better than that belter - northern bloke, trying to be overly happy - who does up old bikes averagely.
