In spring 2015, Shimano presented the new XTR groupset in 1-, 2- and 3x11 versions. Now the XT groupset is also getting a completely new look plus the same technology as the XTR. With the widest possible range of up to 33 gears, Shimano now also caters for every type of rider with the XT. The two-speed version "True Trail" offers the most options. Three different gradations are available with the chainring sizes 34/24, 36/26 or 38/28. The triple crank is only available in 40, 30 and 22 tooth gradations.

No matter which combination you choose, the XT cassettes feature Rhythm Step technology. This is intended to ensure impact-free shifting in the upper third, where the chain jumps become larger, which should allow the rider's energy to be used more efficiently. In the 11-40 cassette, it is the sprockets 27, 31, 35 and 40, and in the 11-42 cassette the sprockets 28, 32, 37 and 42 that feature Rhythm Step technology. Furthermore, the HG-X11 chain with its asymmetrical plates and SIL-TEC treatment ensures that every shift and crank revolution is as friction-free as possible.

The new XT cranks will also be available in a wider version for the wider 27-plus wheels. Their double cranks come with 36/26 chainring sizes, while the single version will be available with a 32 chainring. Shimano meets the needs for plus sizes completely with the FC-M8000 OLD hubs (OLD = Overlock Nut Dimension) in 148 millimeter width.

For the time being, the new XT comes as a mechanical version. It is possible that a Di-2 version will be available this year. However, it can be assumed that Shimano will wait another year before taking this step.

Less effort thanks to new changer and shifter
The Deore XT M8000 changer has been completely revised and includes the optimized Shadow RD+ technology. Thanks to this, Shimano promises that less effort is required to operate the shifter. In addition, it should also keep the chain more stable on the sprocket and guarantee crisp yet smooth gear changes.

The derailleurs have also been optimized. These also result in a clear reduction in the shifting force required. This is not least due to the new cable routing. The new front derailleurs also offer more tire clearance - ideal for bikes with short chainstays. The front derailleur models FD-M8025, FD-M8020 2x11 or FD-M8000 as a 3x11 option have also been adapted to trail bikes with a lot of suspension travel. They are available with high and low mounting clamps and as D-type and E-type models.

It's not just the new derailleurs and shifters that contribute to smoother shifting, the shifters have also been "finely washed". In combination with the Optislim cables, the long, bent flywheels and the grooved release wing on the inside should result in a 20 percent reduction in shifting forces.
The switches still feature the 2-way multi-release mechanism. Three options are also available: the classic SL-M8000, the I-SPEC II (SL-M8000-I) for new XT and XTR and the I-SPEC B-type (SL-M8000-B-I) for older or lower-step brake levers. This allows the new drivetrain to be combined with various Shimano brake types.

Stoppers, rolling stock and (binding)
The hydraulic DEORE XT disc brake was the first from Shimano and has been a benchmark in terms of braking power, consistent braking performance and modulation ever since. The DEORE-XT-M8000, which is stepped up to the trail sector, continues to meet these standards, but is improved with a lighter and more durable master cylinder. Refined servo wave levers also result in improved feel and feedback as well as more braking power with shorter lever travel.
The lever width can still be adjusted without tools. The XT brake can be combined with brake rotor sizes from 140 to 203 millimetres.

With a focus on weight reduction and durability, the development of the latest XT wheel has progressed. The new Deore XT Race and XT Trail wheels - both in 27.5-inch and 29-inch - are handmade with tubeless-ready aluminum rims. While the race versions have an inner width of 20 millimetres, the trail wheels have 24 millimetres. Nevertheless, the wheels are around 40 grams lighter than the previous models - after all.

The connection between rider and bike - the pedals - is getting wider. The cross-country pedal "XT-PD-M8000" has increased in width by 2.8 millimetres, while the trail pedal "PD-M8020" has gained 3.3 millimetres. In addition, the height of both has shrunk by 0.5 millimetres. The additional contact surface is intended to increase their efficiency by 7.7 and 11.7 percent respectively.
