We found the latter slightly less smooth and a little louder when shifting, when reviewing back-to-back.

Both are charged via a USB cable connected to the same design of charging port on the rear derailleur too.\u00a0<\/p><p>The semi-wireless connection between the shifters and the derailleurs uses coin cells to power the wireless transmitter in the shifters. Here, 105 Di2 makes up for the lack of a third shift button by using the space to house two CR1932 lithium coin cells, rather than Ultegra\u2019s single one.\u00a0<\/p><p>In theory, this gives you twice the battery life before you need to replace them, but even Ultegra has a claimed runtime of between 18 months and two years, so as long as you keep an eye on the battery level periodically, you\u2019re unlikely to run out of juice.\u00a0<\/p><h3 class=\"wp-block-heading\">Braking<\/h3><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1600\" height=\"1067\" src=\"https:\/\/c02.purpledshub.com\/uploads\/sites\/39\/2023\/10\/Liv-Avail-Advanced-Pro-0-13-3a27d6f.jpg\" alt=\"Liv Avail Advanced Pro 0 road bike for female riders\" class=\"wp-image-750126\"\/><figcaption class=\"wp-element-caption\">Braking from both groupsets was superb during testing, but Ultegra incorporates Servo Wave tech. &#8211; Sam Voaden \/ Our Media<\/figcaption><\/figure><p>Both Ultegra and 105 Di2 have a <a href=\"https:\/\/www.bikeradar.com\/advice\/buyers-guides\/road-disc-brakes-everything-you-need-to-know\">hydraulic disc brake<\/a> option, but only Ultegra also handles <a href=\"https:\/\/www.bikeradar.com\/advice\/buyers-guides\/bike-brakes\">rim brakes<\/a>, albeit with different shifters.<\/p><p>Both 105 Di2 and Ultegra\u2019s disc brake pads retract a 10 per cent greater distance than in Shimano\u2019s previous-generation groupsets, so brake rub is less likely.<\/p><p>Ultegra disc brakes include the same Servo Wave tech as Dura-Ace. This offers non-linear brake pad progression, so the pad starts to engage sooner in the lever stroke and there is a smoother bite as you go deeper into the stroke.\u00a0<\/p><p>While 105 brakes don\u2019t include Servo Wave, it\u2019s not something that affects the excellent brake modulation and power on offer.\u00a0<\/p><p>They also don\u2019t incorporate Freezr heat sink fins.

Unless they make a perverse decision to downgrade something, the electronics and shifting are almost identical between groupsets.<\/p><p>So it is with Shimano Ultegra and 105 Di2. The latter removes some nice-to-haves at the margins, but most riders won\u2019t judge these critical and the ride experience is near-identical.<\/p><p>The majority of riders will be choosing between buying a complete <a href=\"http:\/\/www.bikeradar.com\/advice\/buyers-guides\/best-road-bikes\">road bike<\/a> specced with either Ultegra or 105 Di2, rather than looking to upgrade their groupset. As such, the 373g or so difference in weight is more than likely to be outweighed by differences in other parts of the bike spec, such as carbon grade and manufacturers\u2019 wheel and tyre choices.<\/p><p>Unless you\u2019re looking for a specialised configuration, such as a 46\/36t cyclocross groupset (or rim brakes), are a die-hard weight weenie (in which case we\u2019d point you to Dura-Ace), or want satellite shifters or an in-series power meter, there\u2019s little reason to choose Ultegra over 105 Di2.<\/p><script type=\"text\/javascript\"><![CDATA[
