Why We Like The Ultegra ST-R8000 STI Shifters

Shimano's Ultegra is often thought of as a budget racer's group or one that was worthy to put on a top tier frame helping to bring the total price down. This latest version performs so flawlessly that unless you are just dead-set on Dura-Ace, you should seriously consider the Ultegra 8000 group. Because it's a serious drivetrain for serious cyclists. The Ultegra ST-R8000 STI Shifters have enough DNA from the new 9100 shifters—themselves perhaps the pinnacle of mechanical shifting—that you will have a hard time separating them as twins.

The lever body is made from Carbon Fiber Reinforced Plastic (CFRP), like the 9100, but the main lever blade is also CFRP rather than the carbon fiber found on 9100. On the scale and in your wallet, you're looking at a 73g and $200 increase. Despite the different materials, the brake reach adjustment has still been increased to fit more hand sizes. Included in that price of admission is the excellent SP41 cable housing and polymer-coated stainless steel cables. The new hoods are also a direct descendant from 9100 and the texture and rubber compound make them an enjoyable hand-hold with or without gloves and during any season.

Old 105 to Ultegra

I've put it through the wringer
Size Bought:
6' 2"

These do in fact shift much better than my old set. It takes a lot less pressure on the lever and less deflection for the shift to occur. I have a Di2 bike, and when it's really cold and thick gloves are needed, it makes more sense to take this bike over the other. With the 105 you really had to crank the lever over to make a shift. With this, it's just a little stab of the lever and you have your gear change. Very smooth. I changed all the other components to Ultegra, so all the shifts are remarkably smooth and quiet. YMMV, but I had a ten year old bike with a short cage 105 derailleur with built in limitations. But the frame was only 900 grams and quite compliant and I felt it was worthy of the investment. Couldn't be more pleased with the outcome.

Worthwhile upgrade

I've used it several times

I upgraded from 105 5700 (10 spd) to Ultegra R8000 and the difference in shifting is night and day. Shifting is light and crisp and the system has never struggled on a shift. The difference is most noticeable on the front chainring shifts from the small ring to the big ring. Whereas the 105 required effort and time to upshift, the Ultegra upshift is almost imperceptible other than the fact that I'm going a whole lot faster. The right shifter now allows you to downshift 2-3 cogs by clicking the lever all the way in. This is really handy for compensating for a front chainring upshift. Unfortunately, you can't upshift multiple cogs in the rear the other way. The shift levers feel really good in the hands and the ergonomics just works. The box comes with a full set of brake and shift cables including housing and hardware. Don't go out and buy your own.
