Attenton 1X drive train fanatics!!! This is your huckleberry!
This deraillieur saved my monster-cross build. Let's face it, most of the components available for a cross bike are too fragile. You can no longer mix 10 spd mountain and road Shimano components due to the dyna-sys shift ratio being different. Sooo...I solved my 1x10 drivetrain issue with this. I changed the jockey wheels out for some higher end sealed bearing units. Most people believe a 9spd rear mech won't work with a 10 spd shifter...this is wrong. It works fantastically!
I'm using a Retro-shift CX 10spd shimano shifter with this 9spd rear mech with updated jockey wheels. I'm using a 42T chain ring with a 11-36 rear 10 spd mountain cassette, 10 spd chain. As far as the rear mech 9spd label-- it speaks to the width of the chain it can handle, not the size of the rear cassette. This rear mech was easy to adjust and shifts effortlessly with positive, crisp shifts. I wanted a clutch style XT rear 10spd mech but the shift ratio won't work with my drop bar monster cross Vassago Fisticuff build. But this turned out to be a great fix! While it doesn't have a clutch, the unit has fantastic rear spring tension and has not dropped the chain. Far more tension than the 105 rear road mech I was using. I'm running a Wolff tooth components front chain ring. This allowed a nice clean build without the hassle of a front mech and double front crank. The gearing has enough steam to sprint respectably in the flats or road, and is very capable in most climbing situations. The climb has to be very extreme before this setup has you walking. If you want to guarantee super climbing ability switch to a 39T chainring, you'll lose some steam in the flats but it's still good for about 22mph. The setup is a compromise, but it is simple and it flat out works. I would say with this exception, most 9spd / 10spd component mixes won't work, but this particular assembly of parts is perfect!
