Review: Shimano Ultegra Di. Slick shifting, flawless performance in all conditions and situations, lighter and improved ergonomics make Shimano's latest Ultegra Di. With all the performance of Dura- Ace at half the price and with a weight penalty that only weight weenies could worry about, Ultegra Di. Ultegra Di. 2 6. 87. Ultegra 6. 80. 0 groupset.

Ultegra Di. 2 is also available with Shimano's latest hydraulic disc brakes, but you can read all about those in this separate review. This review focuses primarily on the shifting performance of the new Ultegra Di. The price is for the shifters, derailleurs, battery, charger and various wiring and control gubbins. You're far more likely to acquire Ultegra Di. Those changes centre around improved ergonomics in the shifter hoods, smaller and lighter derailleurs, and the E- Tube system that allows every shift button to be customised.

Using the new Di. They're noticeably slimmer and fit my hands much better than the mechanical versions (I do have small hands though). For all types of riding I found the compact shape preferable, and I really appreciate the small diameter of the main body that make it easier to wrap your fingers around when you're climbing out of the saddle. The shift buttons have been revised; the contrast between the surface texture of the two buttons is now more pronounced. Despite these changes, which are an improvement over the previous Ultegra Di. I would like Shimano do a lot more to improve the feel of the buttons.

Shimano just launched the M9000 XTR mountain bike component group (see our first look here), moving to 11-speeds and adding a single chainring option.

The two are still close together, and with thick gloves on it's sometimes difficult to locate them. Also, They're just a bit lifeless and devoid of any of the feedback that a mechanical groupset provides. That's really my main gripe with Di. I know plenty of people who don't feel the same, so that's a really personal thing. Despite this, I can quite happily get on with Di. I just can't put up with it.

And after a while you soon adapt and just get on with riding your bike. Ultegra Di. 2 uses Shimano's E- Tube (that's the wiring and communication system, based on the CAN bus protocol) which has the potential to allow the shift buttons to be fully customised.

Out of the box a single press and hold of a shift button will cause the rear derailleur to move across the entire cassette. You could specify a two or three sprocket shift, you can even change the shift speed with five settings available, and many other options are available too. The wiring is plug- and- play – so it's easy to set up – and is all controlled by a junction box that you strap to the underside of the stem. Concealed under a small flap on the side of this box is the charge port, and is also where you plug in a PC if you want to customise the shift buttons. There are optional sprint, Roubaix and aero buttons that can be plugged into the system too. The charge port is for the internal battery; if you have an external battery you need to remove it to charge the system. The updated derailleurs have been given the same smaller dimensions as the latest Dura- Ace Di.

Visually they look a lot better on any bike, still chunkier than mechanical but much less so than previously. The rear derailleur is much slimmer and a better looking unit, with neater wiring. It of course goes up to 1. Dura- Ace and now available at half the price. There are two versions of rear derailleur available, the long cage option accommodating a 3. The long cage will make an ideal climbing or cyclocross option, the latter paired with the Ultegra 4. A neat feature of the rear derailleur is the a crash protection facility that automatically disengages the motor so the mech can move out of the way to avoid an expensive replacement bill.

With a rear derailleur costing . It doesn't take much effort to change gear, and while in perfectly dry riding conditions a good mechanical groupset is very similar in performance, it's when the weather turns bad that Di. A couple of rides and races run in heavy rain and cold temperatures proved that Di. I've done rides so wet that I've had inadequate feeling in my fingers and hands to change gear on a mechanical groupset (a particularly wet 2. Audax) but Di. 2 in the same conditions allows you to still change just fine. Don't get me wrong, it's not just in foul conditions that Di.

Even in the most perfectly glorious cycling conditions, Di. New Windows 10. Every gear change is perfect, there's never a missed gear, which is useful when you're climbing and reaching desperately for an easier gear. The buttons are reached easily from the hoods, thanks to the more compact form factor, and equally from the drops as well. The auto- trim feature on the front derailleur is one of the best features of the entire groupset, and avoids chain rub that can't always be eliminated on a mechanical groupset. The brain of the Di. You can customise the trimming function but it works so well out of the box that we felt no need to. You might be forgiven for not even noticing the addition of an extra sprocket when you're using the 1.

That flawless performance and complete lack of degradation, of the sort you can't expect with a mechanical groupset for every ride – unless you're fastidious in maintaining and servicing the cables – is really Di. It always works brilliantly every time you hit the road, whatever the weather or conditions.

That makes it an appealing choice of a bike you want to ride year- round, through the full gamut of British weather. There's no cables to degrade or cable outers to shift in their housings. Once it's set up to shift perfectly, that's what it continues to do for mile after mile. It's all of performance of Dura- Ace but at a much reduced cost and with only a weight penalty that the seriously weight conscious need worry about. Really, unless you're building a superlight superbike, you'd be daft to buy Dura- Ace over Ultegra. Switching from mechanical to electronic does take a little getting used to, but a few hours in the saddle and you'll be just fine. While I'm not the biggest fan of the way the shift buttons 'feel' when you operate them, there is no denying they work brilliantly when pressed, delivering rapid and precise gear changes each and every single time.

No matter the weather, rain or whether coated in mud. The battery life is excellent, long enough that you only need charge it occasionally. The internal seatpost battery does make charging a little less practical for some - you can't easily remove the battery and have to keep the bike near a power source so you can plug the USB lead into the control box under the stem, but that's a minor impractically. You can still buy bikes with external batteries, but they're becoming markedly less common. Personally I prefer the feel of a well maintained mechanical groupset, but there's the crux of the matter; Di. For British cyclists, that's a very appealing proposition.

What do the manufacturers say about it? How does that compare to your own feelings about it? Our Ultegra Di. 2 series with electronic shifting is .

Would you recommend the product to a friend? Yes. Anything further to say about the product in conclusion?

Your feet will clip in and out with the standard reliable Shimano clack, there's a wee bit of sticky release trouble when things get dry, gritty or claggy, and you have to get stompy on the pedal when riding in stupid- thick mud, but the open design of the cleat interface lets your standard issue gloop through without any bother. In conclusion.. Great value SPDs, a little heavy, but feel under foot isn't noticeable.
