For 270 euros, the SLX groupset previously the cheapest with 1x12 gears from Shimano. This is now set to change. With the introduction of the Deore M6100, the Japanese company is installing 12 gears for the first time, even below the SLX level. In order to make the number four in Shimano's component hierarchy suitable for the masses, Shimano is even further below the 300 euro price limit with the new Deore. The 11-speed and 10-speed versions of the Deore will still be available. All new Shimano Deore 12-speed components will be available from specialist retailers from June 2020.
How Shimano's new entry-level groupset fares against Sram
According to the manufacturer, the price of the new Deore groupset is around 270 euros. The actual price is therefore likely to be just under 250 euros. This means that the Deore remains at the same price level as the 2x11 Deore counterpart and the 12-speed Sram SX Eagle entry-level groupset (around 250 euros). The Sram NX Eagle is currently available on the Internet for around 280 euros.
Shimano 12-speed groupset relies on XT/XTR shifting technologies
The centrepiece of the new Deore M6100 is the stylish 12-speed crankset. Just like the more expensive SLX, XT and XTR models, the M6100 also benefits from Dynamic Chain Engagement+ technology. The specially shaped teeth are designed to favour the retention of the chain in the chainring and reduce friction and noise.
The direct mount fastening not only holds the chainring securely in place and contributes to a clean look, but also makes it easy to change the chainring. In addition to the crank arm length of either 170 or 175 millimetres, customers can also choose between two different chainring sizes with 30 or 32 teeth. In addition, the chainrings of the larger siblings (Shimano SLX, XT and XTR) are compatible with the new M6100 family member. It is therefore up to the user to expand the range with a 28, 30, 32, 34 or even 36 tooth chainring. Finally, Shimano offers the crankset with three different Q-factors (distance between the two crank arms when mounted): 172 millimetres, 178 millimetres and 181 millimetres.
Shimano uses 12 stainless steel sprockets with a range of 10-51 teeth on the cassette for the new Deore groupset. As with the other Shimano 12-speed drivetrains, the new Deore is designed to shift faster, more precisely and more reliably than the predecessor gearshift unit. In combination with the special M6100 chain, Shimano claims to have achieved a significant increase in shifting performance compared to previous Deore models.
At the rear, a Shadow RD+ rear derailleur on the new Deore ensures precise and smooth gear changes and more chain tension in rough terrain. We count 13 teeth on the idler and tension pulley. The shift lever also carries the genes of the more expensive Shimano 12-speed MTB drivetrains. Thanks to the I-Spec EV clamp, the smaller Deore sibling can also be fitted with shift and brake levers with just one clamp. With Rapidfire Plus, the rider can shift down by up to three gears with just one press of the lever. In addition, the "Two Way Release" function releases the shift cable either by pulling with the index finger or pressing with the thumb. Just as we know it from Shimano gears.
Deore disc brake now also available with four pistons
Together with the new groupset, Shimano now also has two new Deore disc brakes in its range. One is the familiar Deore with a two-piston brake calliper, the other is a four-piston version specially designed for trail/enduro use. On both models, the pilot pulls the same revised brake lever, which, according to the manufacturer, should provide more stability with an additional support on the handlebars.
To complete the Deore cockpit, Shimano now also offers a remote lever for retractable seatposts.
