The Japanese component giant announced the launched of a new 11 speed version of it’s popular 105 groupset – giving the entry road group even greater parity with it’s bigger siblings.
Shimano is referring to it’s new trickle down groupset as 5800, which features many of the attributes of the upper level Dura-Ace and Ultegra groups.
According to Shimano, “The main thing about 105 is that it’s now 11-speed,” “With it being 11-speed it brings many of the functions and features that you get with both Ultegra and Dura-Ace to a much wider range of riders.”
In addition, Shimano says, “The shift levers have a compact grip which provides more comfort and control during a ride. The lever can be customized for different hand sizes with a 10mm screw-type reach adjust."
“The front derailleur has a longer link arm combined with a new spring mechanism. Also, the rear derailleur has a new spring mechanism and cable pitch, which provides robust adjustability.”
The crankset will be available in 53/39T, 52/36T and 50/34T configurations. However, since the new 5800 maintains the same center bolt diameter (BCD) design for both compact and traditional double chainsets, users can swap chainrings without the need of changing out the whole crankset.
Both a 12-25 and 11-28 cassettes will be available, along with a new 11-32 option. A short cage derailleur will handle cassettes up to 28T, but a long cage derailleur will be required to handle the 11-32.
Shimano also claims to have improved braking power by 10% over that of the previous 5700 series, due to the 5800’s new symmetrical dual-pivot brake caliper. In addition, the new brakes have a higher arch that can accommodate tires up to 28c. There will also be a direct mount brake version (BR-5810) available, to address the needs of triathletes and time trialists.
The 5800 will be available in both black and silver finish, and it’s slated to be released in June.
