Shimano Dura-Ace ST-R9160 Di2 TT / Triathlon STI Brake Lever

With Di2 technology shifting is easy and precise - just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gear.

For time trial and triathlon use, the DURA-ACE ST-R9160 levers reduce drag thanks to their aerodynamic design. The one-button layout integrates seamlessly with Shimano's Synchronized Shift.

Technology

SLR-EV

SLR-EV is SLR with a dual symmetric pivot brake caliper. The short-arm brake design employs two bearings and a roller to realize greater efficiency in the pivot area and deliver superior modulation and power for braking. Together with the BC-9000 brake cable, the latest calipers deliver 36% more braking power than Shimano’s previous brake model. And we offer 2 axle symmetric brake caliper and fork mount and chain stay mount type (BR-R9100 / 6810 / 5810).

SEIS

A technological innovation of the computerized shifting system based on the Di2 concept with which is called, the SEIS (Shimano Electronic Intelligent System).

The SEIS innovative shift technology is still based on the Shimano Index System (SIS) that has proved its superior gear changing characteristics over the years. The big difference is that in this case, the shifting action is provided for by electronics instead of mechanics.

This electronic shifting system has been extensively tested over past two years by several professional riders in all conditions possible, such as rain, mud, low temperatures, cobble stone roads and combinations of all of these at the same time.

Shifting is executed by simply pressing the button. No power is needed to shift, which gives important advantages since it is easier now to always keep a tight grip on the handlebar and to keep your concentration on riding instead on shifting.

The shift system allows accurate and effortless shifting in difficult circumstances for example when you have cold hands or when you are completely exhausted. Furthermore, the shifting performance will never be affected by contaminated or stretched cables since the shifting signal is transferred electronically. The operating buttons work similarly to mechanical Dual Control Lever so you don’t need to re-program your mind for the SEIS.

E-Tube

E-Tube is Shimano's “service” that uses websites or apps to maximize the enjoyment of riding a bicycle by connecting the riders, the bicycles and Shimano.

Shimano’s genuine application E-Tube Project for Mobile allows you to customize your bike, update firmware, and maintain it by connecting it wirelessly to your bike. You can also get the more detailed bike maintenance by connecting to your bike by wire with E-Tube Project for Windows V4 application.
