I have a five year old cyclocross bike with Tiagra 2x10 shifters and mechs. I have no idea what series they are (can't see any identifying numbers) but I want to replace the shifters with the newer 10 speed Tiagra model but am clueless as to whether they are compatible.
I would have thought so but have read a few things online to say not.
Don't know much about roadie stuff so if anyone could shed some light on this I would be very grateful.
4700 isn't compatible with the other 10-speed components, you'd need a new rear mech too.
Thanks for that. I presume front mech too? Would the original cassette still be OK?
front mech should be fine, as should the cassette.
Awesome, thanks for the advice
BGD could be interested in the older sti and rear mech if you sell and they are working fine
OK, no problem. All work fine, had very little use really. Will give you a shout when I've got it all sorted.
peel back (that is upwards) the hood near to where shifter clamps to bar on outside of shifter the shimano part number should be there....only thing i know on Tiagra compatibility is that at some point it def became the quirky odd one out
Just in case it's of interest, any 11 speed shimano road mech (including the clutch ones) should also work with 4700 over a 10 speed cassette.
Interesting - I have a full Tiagra 2x10 in the spares box. So is it the rear mech that is the limiting factor (non compatible).

Not entirely true...
Had 4700 rear mech working just fine with 5700 STIs.
Cheers!
I.

Are you sure it was a 4700? The ratios look like it would undershift massively.
