One thing that has always stood out and impressed me about Shimano is that its lower-tier components perform nearly on par with those at the top-of-the-line. I\u2019ve found this to be particularly true of its mechanical off-road drivetrains, with Deore and SLX (RIP) usually shifting as crisply and consistently as XT and XTR.\u00a0<\/p>\n

Sure, there\u2019s a slight weight penalty, less bling factor, and a few other minor differences, but otherwise, the shifting performance has always been roughly equivalent in my experience. So, when Shimano finally brought the latest Di2 off-road drivetrains to market last year<\/a>, I hoped the same would be true for its fancy wireless shifting. When given the opportunity to try out the new Shimano Deore Di2 Upgrade Kit<\/a>, I jumped right on it to find out.\u00a0<\/p>\n

A relatively mild winter meant plenty of testing days over the past few months.<\/figcaption><\/figure>\n

I got the Deore Di2 Upgrade kit back in early January<\/a> and promptly installed it on my personal trail bike. I\u2019ve been riding with it on and off ever since, switching frequently between other test bikes, some of which have been equipped with the higher-end XT and XTR Di2 drivetrains. I\u2019ve learned that it works almost identically to its more expensive siblings, and you don\u2019t need<\/em> to spend more for wireless.<\/p>\n

What\u2019s the Difference?<\/h2>\n

With performance and weight gaps narrowing between its groupsets, Shimano recently decided to simplify and put SLX out to pasture. Now, at the higher end of the off-road lineup, the hierarchy is XTR, XT, and Deore. Among the new Di2 components, there are many similarities, including the general form factor and the same dual-spring, clutchless mechanism in the derailleur. They also use the same batteries, chargers, and electronics, and the derailleurs and shifters are all cross-compatible.\u00a0\u00a0<\/p>\n

Beyond the more exciting, shinier finishes on XT and XTR, there are several other notable differences. For the derailleurs, weight is one of the biggest, with the steel cage on Deore adding some heft compared to the aluminum and carbon cages on the XT and XTR, respectively (check out the weight comparison below for more details). Additionally, both XT and XTR are offered in long (SGS) and short (GS) cage configurations, while Deore is only offered with a long cage.<\/p>\n

\"XTR<\/a>

The XT and XTR shifters also offer more features than Deore. Deore\u2019s shift paddles are fixed in position, while the others offer 4-way adjustment via ball joints to optimize their positions. Deore is also single-click only (or hold for multi-shift), while XT and XTR feature double-click to shift one or two gears at a time. With fewer features and hardware, the Deore shifter actually weighs less than its more expensive counterparts.<\/p>\n

Obviously, price is also a factor. The Deore Upgrade Kit retails for $675, and can often be found on sale for less<\/a>. The XT Di2 Upgrade Kit<\/a> will set you back $860, while the XTR Di2 Upgrade Kit<\/a> goes for $985. Check out the weight and price breakdown below. Note that the battery is the same for all models and weighs 24 grams \u2014 the weights listed below include the battery because the derailleur does not function without it.<\/p>\n
