Shimano mix 'n' match

Can I use a Shimano MTB rear mech (10 speed) with road Shimano brifters?
Also, cantis or v-brakes for a CX build?
It's just a hill. Get over it.

    I believe the MTB and Road brifters/ derailleurs use different cable pull ratios, so no, I don’t think you can. I personally would use disc brakes for a CX build.

    However, I believe Di2 components are compatible. https://bike.shimano.com/en-EU/e-tube/project/compatibility.html#guide_list

    You can run the shifters with an MTB mech if you use one of these

    Never used one myself but I believe they work. Regarding the brakes, mini-Vs are your best bet. Road brifters don't pull enough cable for proper V brakes.

    Thanks.
    I've just bought a cheap CX frame with canti mounts, it'll be a project / fun / hack bike, so not spending real money. But yes, I prefer discs!

    It'll be fun whatever, I must confess I found the canti's on my old bike dire if the rim was dirty. I got some used mini Vs to try, but never got round to fitting them. Think they might be in my spares box if you're interested Sam.
    JBA is selling some used MTB 10 speed stuff on here I see.

    Happy to recycle, drop me a PM. TIA.

    Go with the cantis and have fun, we managed for years with them.

    Having had side pulls on steel rims on my first bike, anything beats that!

    New Question! I had a mad thought whilst perusing Shimano compatibility charts: I have some nearly new DA down tube shifters that I could use on my turbo bike, but they are nine speed*. Could I use them on a 10-speed set up, but just 'lose' a gear? I don't use the smallest sprocket much on the turbo, so that would be no great loss. I could then use the (perfectly functioning) STIs on the CX bike.

    *I won't mention that I just sold a brand new 9-speed chain and cassette as part of a shed clearout...

    If they only work in indexed mode, probably not. If they have an old school friction mode then you can probably use all 10 gears

    That's a good point, my son's road bike has 9 speed DA downtube shifters and they can be switched between indexed and friction I believe.
