Can we just have a longer lead, please, Shimano?<\/p><p>In terms of battery life, Shimano claims a Di2 system should have enough juice for about 1,000 kilometres of riding, whereas SRAM says each battery will last for around 60 hours of riding.<\/p><p>In practice, battery life simply isn\u2019t an issue for either system, though.<\/p><p>As with anything electronic \u2013 be it a <a href=\"https:\/\/www.bikeradar.com\/advice\/buyers-guides\/best-bike-lights-for-road-cycling\">light<\/a>, a <a href=\"https:\/\/www.bikeradar.com\/advice\/buyers-guides\/best-bike-computers\">bike computer<\/a> or my phone \u2013 I\u2019ll always charge my groupset before a big ride anyway, so it\u2019s very rare I run out of battery with either.<\/p><p><strong>Winner:<\/strong> SRAM Force AXS<\/p><h2>Connectivity<\/h2><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" width=\"1600\" height=\"1067\" src=\"https:\/\/c02.purpledshub.com\/uploads\/sites\/39\/2024\/01\/SRAM-Force-AXS-App.jpg\" alt=\"SRAM Force AXS groupset- App\" class=\"wp-image-813018\"\/><figcaption class=\"wp-element-caption\">The SRAM AXS app has an array of features and can record reams of data, whereas Shimano\u2019s E-Tube app is mainly used for setup and making adjustments. &#8211;

Russell Burton \/ Our Media<\/figcaption><\/figure><p>For me, the act of pressing the two shifter buttons on a SRAM AXS groupset to initiate a front shift, instead of just one on a Di2 groupset, can almost convince you the SRAM front shifting is fractionally slower, because you have to do that tiny bit more to make it happen.<\/p><p>In reality, though, front shifts on both groupsets are near instantaneous once the buttons have been pressed.<\/p><p>The main differences in terms of the drivetrain, then, come in terms of the gearing options (which we\u2019ll come to shortly), and the fact the SRAM Force rear derailleur has a clutch and the Ultegra one doesn\u2019t.<\/p><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" width=\"1600\" height=\"1067\" src=\"https:\/\/c02.purpledshub.com\/uploads\/sites\/39\/2024\/01\/Shimano-Ultegra-Di2-R8100-vs-SRAM-Force-AXS_03_Front-derailleurs.jpg\" alt=\"Shimano Ultegra Di2 R8100 and SRAM Force AXS groupsets go head to head\" class=\"wp-image-813011\"\/><figcaption class=\"wp-element-caption\">Shimano&#8217;s front shifting has long been class-leading, but SRAM has now caught up with Force AXS. &#8211;

Russell Burton \/ Our Media<\/figcaption><\/figure><p>Shimano has stuck with more traditional ratios, with classic semi-compact (52\/36t) and compact (50\/34t) chainring options up front and an 11t smallest sprocket on the cassette at the rear.<\/p><p>As with 105 Di2, there\u2019s no more \u2018standard\u2019 53\/39t option at the Ultegra level anymore. If you want those ratios, you\u2019ll need to look at third-party chainring options, or stump up the cash for the 54\/40t Dura-Ace R9200 crankset.<\/p><p>Shimano Ultegra R8100 cassettes max out at 34t, but there\u2019s also a tighter 11-30t option if you prefer.<\/p><p>The Japanese brand has also reworked its cassette sprocket progression, making them less linear from top to bottom. This means you get more tightly spaced gears at the lower end and wider ones up top.<\/p><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" width=\"1600\" height=\"1067\" src=\"https:\/\/c02.purpledshub.com\/uploads\/sites\/39\/2024\/01\/Shimano-Ultegra-Di2-R8100-vs-SRAM-Force-AXS_07_Cassettes.jpg\" alt=\"Shimano Ultegra Di2 R8100 and SRAM Force AXS groupsets go head to head\" class=\"wp-image-813015\"\/><figcaption class=\"wp-element-caption\">The cassettes are more closely matched, but SRAM&#8217;s use of the 10t cog helps increase the gearing range with smaller chainrings. &#8211; Russell Burton \/ Our Media<\/figcaption><\/figure><p>SRAM\u2019s Force AXS cassettes (which are available in 10-28, 10-30, 10-33 and 10-36t sizes) were already on board with this non-linear gear progression, but they also use a 10t smallest sprocket to increase their overall range.<\/p><p>This is then paired with a set of smaller, more tightly spaced chainrings up front \u2013 with a 13-tooth jump between the rings, as opposed to 16t on Ultegra chainring sets.<\/p><p>Paired with SRAM\u2019s 48\/35t crankset, then, Force AXS offers a top gear ratio that\u2019s marginally bigger than with a 52x11t. At the other end, 35x36t offers an easier gear ratio for climbing than possible with the 34x34t lowest gear offered by Ultegra (when using the 50\/34t compact <a href=\"https:\/\/www.bikeradar.com\/advice\/buyers-guides\/cranksets\">crankset<\/a>).<\/p><p>Alternatively, you can have a 46\/33t crankset for easier overall gearing or a 50\/37t version if you need even bigger gears. You could also have a tighter cassette if you like really small jumps between the gears.<\/p><p>Whatever you choose, though, you essentially get the best of both worlds.<\/p><p>Of course, some may decry the <a href=\"https:\/\/www.bikeradar.com\/features\/friction-facts-free-speed-from-proper-shifting\">marginal increase in drivetrain friction from using smaller cogs and chainrings<\/a>, but this isn\u2019t something I can detect while riding.<\/p><p><strong>Winner:<\/strong> SRAM Force AXS<\/p><h2>Braking<\/h2><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" width=\"1600\" height=\"1067\" src=\"https:\/\/c02.purpledshub.com\/uploads\/sites\/39\/2024\/01\/Shimano-Ultegra-Di2-R8100-vs-SRAM-Force-AXS_06_Brake-calipers.jpg\" alt=\"Shimano Ultegra Di2 R8100 and SRAM Force AXS groupsets go head to head\" class=\"wp-image-813014\"\/><figcaption class=\"wp-element-caption\">Shimano has raised the bar with its latest hydraulic disc brakes, but SRAM&#8217;s stoppers are still excellent. &#8211;
