New Shimano 105 series receives tech boost and disc brakes

Today’s road riders demand much more than pure on-the-rivet speed. They expect comfort, control and versatility from their bikes, and enjoyment and goal achievement to boot. 105 level riders expect the latest pro level features but they also want to do more with their bike than racing and training. So step forward the new 105 R7000 generation with customizable disc or rim brakes and wider cassette options to help you remain in comfort and control wherever you’re riding.

Coming with the high-end aesthetic and race characteristics of its Dura-Ace and Ultegra big brothers, the new 105 series also considers that most riders will use their bikes for purposes other than competitive racing. 105 is Shimano’s first level 11-speed groupset for those who are seriously committed to road bike riding, but that definition now becomes broader with the inclusion of superior handling and adaptable control to master different riding situations.

The biggest news for new 105 is the addition of disc brakes to the series line up. New flat-mount BR-R7070 calipers are compatible with ICE TECHNOLOGIES pads and UCI-compliant non-90 degree SM-RT70 rotors (including a new 140mm size) to offer greater cooling efficiencies. Brake operation is handled by new ergonomically shaped Hydraulic dual control levers (ST-R7020), matching the design of Ultegra ST-R8020 levers with a greater range of reach adjustment for different hand sizes. To provide even greater customisability, 105 R7000 offers a version of the dual control brake/gear lever (ST-R7025) to better suit smaller hands by being angled closer to the bar and taking more of an outboard position for better connection and to avoid interference with the handlebar drop during lever operation.

Whether from the rim brake (ST-R7000) or disc brake (ST-R7020/25) lever, gear shifts have been redesigned to offer faster and lighter shifts with a shorter stroke compared to the 105 5800 series. The front derailleur has a compact toggle (pivot) design, better tyre clearance and an integrated cable tension adjustment port (2-mm Allen key) removing the need for an in-cable barrel adjuster. The optional long cage rear derailleur (RD-R7000-GS) can accommodate up to an 11-34T cassette and is designed with a low profile SHIMANO SHADOW RD style to tuck it below the cassette and chainstay.

Updates within the drivetrain include a new mid-compact 52-36T crankset, to add to the 50-34T and 53-39T cranksets, and new 11-30 (CS-R7000) and 10-speed compatible 11-34 cassette (CS-HG700-11) options to better suit gravel, adventure or CX riding. Together with this the inner crank ring has been positioned to reduce the effects of cross chaining or chain drop, better suiting bikes with disc brake criterium racing bikes.

Increased control and reaction were two points we concentrated developments on, combined with what people have always expected from 105, great versatility and value for riders. With 105’s suitability for a large portion of today’s diverse road bike styles we hope to unlock the potential of where and what it’s possible to ride on a road bike.

who cares about the weight vs Dura Ace....? you are buying a budget groupset - if you don't want the weight then buy the Dura Ace.

I think the point could be that its not a whole lot heavier than Dura Ace.

exactly my point yes.
Weighted 6800 and 5800 against each other when I switched groupsets on two of my bikes. Weight difference on STI's and deraileurs were very little...

And from another article:

 

 

Shimano offers the BR-R7000 series brakes in versions for direct mount front, seatstays, and chainstays configurations.

Great stuff. Been waiting for an entry level road disk group-set to mount on a Kona Rove. 

Will definitely consider this group for a touring bike setup!

Absolutely nothing wrong with 105...good value for money gruppo!
