Now we\u2019ve got a complete groupset in for review and we\u2019ve started off by putting everything on the scales to find out how much each component actually weighs<\/p>\n<section

offer.\u00a0<\/p>\n<p>First up, it\u2019s semi-wireless with a non-wired connection between the shifters and the rear derailleur driving shifting.<\/p>\n<p>The shifters lose some functionality seen on Ultegra and Dura-Ace, such as a third button and the option to add satellite shifters.<\/p>\n<p>In compensation, 105 Di2 levers have space for two coin cells rather than one, doubling battery life.\u00a0<\/p>\n<p>There are 50\/34t or 52\/36t <a href=\"&quot;https:\/\/www.bikeradar.com\/advice\/buyers-guides\/cranksets\/&quot;\">chainset<\/a> options with a wide range of <a href=\"&quot;https:\/\/www.bikeradar.com\/advice\/sizing-and-fit\/what-is-the-best-crank-length-for-cycling&quot;\">crank lengths<\/a>, but there\u2019s no <a

href=\"&quot;https:\/\/www.bikeradar.com\/advice\/workshop\/bike-cassettes\/&quot;\">cassettes<\/a> offering 11-34t or 11-36t range, although without the faster-shifting and smoother Hyperglide+ technology of Ultegra and Dura-Ace.<\/p>\n<p>Like those groupsets, 105 Di2 uses <a href=\"&quot;https:\/\/www.bikeradar.com\/features\/6-of-the-best-disc-brake-rotors\/&quot;\">brake rotors<\/a> and chain borrowed from Shimano\u2019s mountain bike groupsets \u2013 in this case <a

<a href=\"&quot;https:\/\/www.bikeradar.com\/advice\/buyers-guides\/bike-brakes\/&quot;\">rim brakes<\/a> and its <a href=\"&quot;https:\/\/www.bikeradar.com\/features\/road-disc-brakes-everything-you-need-to-know\/&quot;\">disc brakes<\/a> don\u2019t have the Servowave tech of its more expensive siblings, but as with them, the <a href=\"&quot;https:\/\/www.bikeradar.com\/advice\/buyers-guides\/disc-brake-pads\/&quot;\">brake pads<\/a> retract 10 per cent further, so you should get less brake rub.<\/p>\n<p>

and size to Ultegra and Dura-Ace. They are larger than Shimano\u2019s older 11-speed electronic shifters from those groupsets.<\/p>\n<p>As with Ultegra and Dura-Ace, the brake lever pivot has been moved to ofer better leverage from the hoods, which cover more of the lever mechanism.<\/p>\n<p>Unlike Shimano\u2019s higher-spec shifters, there\u2019s no \u2018hidden\u2019 third button, so you can\u2019t programme it to handle screen changes on a <a href=\"&quot;https:\/\/www.bikeradar.com\/advice\/buyers-guides\/best-bike-computers\/&quot;\">bike computer<\/a> or other functions.<\/p>\n<p>You can\u2019t fit satellite shifters either, because there\u2019s no port. In return, the saved space in the lever body is used to provide each shifter with two coin cells rather than one, which Shimano says increases battery life to as long as four years.<\/p>\n<p>Shimano has a claimed weight of around 20g less than our measured weight \u2013 quite possibly because our shifters had brake fluid in them.<\/p>\n<ul><li><strong>Claimed weight:<\/strong>
