Which Groupset?

I have a shifter in shed, you want? tenner.

142 mm rear spacing needed apparently so you'll need that and a specific Campagnolo H crankset

Right hand clicky clicky give me 10 speeds yes?

indexed yeah .. I wanted to see if it will work with DynaSys rear mech .. never tried. I am in SE1 during the day if you want to pick up.

90% certain its microshift something

Yeah that seems reasonable. What / where are you working?

Sea containers house

Easy peasy then.
I'll drop you a pm...

Centaur replaces Veloce as Campag's entry level group. Long time coming really with 10spd Veloce being more expensive than 105.

Interesting decision to make the cranks/BB Ultra Torque with Potenza the only groupset remaining with Power Torque.

New potentza hydraulic has a ultra torque chainset apparently

Apparently mechanical Potenza has Ultra-Torque now too I've read. Just over a year since they launched it with Power-Torque+ ?

Dunno where you read this but everything I saw said standard 135mm rear spacing.

I've got 4700 and 5800 running on my bikes at the moment. 4700 front shifting is excellent but requires slightly more of a "push" than 5800.

I've got nine speed Chorus on one of my bikes. I'd quite like a compact chainset on it, how feasible would it be to put the new Centaur cranks on it ?

Issues around 9 speed chain on 11 speed rings ? Front mech shifting issues ?

I've done it ok (not Campag mind you). You might have some chain rub issues if you are in an inner ring/small sprocket combo but otherwise it seems fine, a bit noisier maybe when the chainline is not centred but not enough to make me want to change it.

Can anyone help with Sram MTB/Road compatibility? I've just picked up a Red 10 speed road shifter on ebay for a 1x10 'cross setup. I'm under the impression the 10 speed MTB stuff will work with this shifter? Ideally I'd get a 10 speed clutched mech like the one below, mostly for the good cable routing (mine comes down the seatstay) and long cage to fit an 11-36, but the clutch cant hurt given I don't have a chaincatcher. Think @Howard might know a bit about this?

IIRC if they are both "exact actuation" you'll be groovy.

They're fine. I ran a Sram red shifter with x9 type 2 clutched rear mech last year, runs perfectly. If you're doing it 1x I'd get a clutched rear mech, if you have a front mech then it's not so necessary

Red 10 speed + x9 short cage type 2 will do 11-36 no probs.

Cheers all! Does anyone want to sell me a mech that will work? I also need a LH lever that matches the 10 speed road one

Cheapest Utlegra group at the mo?

If you're buying Utlegra groupsets I don't think anything Shimano has to offer is likely to be cheaper.
