  • Description

    The Shimano ST-6870 features Di2 technology shifting for easy and precise control - just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gear. Programmed automatic motion at the touch of a switch makes this derailleur quick, smooth and effortless to shift.

    The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts.

    Key Features:

    • Di2 technology shifting for simple and precise control
    • Programmed automatic motion at the touch of a switch makes this derailleur quick, smooth and effortless to shift
    • Removal of traditional mechanical cables in favour of electrical wires eliminates poor shifting caused by contaminates, corrosion and stretching, and also provides effortless gear shifts
    • Derailleur contains a saver (fuse) function, where the inner structure is protected from strong impacts
    • 11-32T wide gear ratio capacity will cater for compact setups as well as the traditional road double
    • High tolerance cold forged aluminium link plates and body construction is extremely light and durable
    • Four self-lubricating micro-machined fluorine-coated link pivot bushings provide low-friction shifting
    • 11-speed E-tube Di2 compatible

DI2 11sp upgrade

Performed a replacement of my DI2 10 speed to Ultegra DI2 11 speed using RD-6870, CS-6800, and CN-9000. The review was straight forward and performs well. Like the narrower ratios I'm getting in the taller gears now. Shimano seems to want you to also upgrade teh front DR, but that's not essential. I may do that if Pro Bike Kit starts selling the Ultegra DI2 front DR.

Ultegra DI2 derailer.

Reliable Ultegra DI2 rear derailer for a great price. Does as good of job as the more expensive Dura Ace.

Great Straight Out Of The Box

You can always count on Shimano products to be top notch and with the prices you can't beat Probikekit. Easy install to my existing Di2 system and with the usual minimal adjustment required of Di2 the rear derailleur works great. Highly recommend moving to the 11 speed if you can as you can especially use that 32 cog if you live in a hilly area. I didn't think I needed it but it certainly is a nice step up. Go cycle your legs off!!!
