Shimano Deore XT M8000 1Ă—11 / 2x11 Groupset
SHIMANO XT M8000 | SHIMANO.COM
The Shimano XT has seen over 32 years of innovation, and almost all of the components in the 2016 Shimano XT are very different from the previous version with the most talked-about change that its now an 11 speed groupset.
With trickle down technology from XTR from the mechanical XTR, and at wallet-friendly price. Here’s some of the main highlights at the new XT:
11 speed drivetrain with 2 cassette options of 11-42T (for single ring cranksets) and 11-40T (for double and triple ring cranksets)
A dedicated single chainring crank with a new broader teeth profile
A new side swing front derailleur, and a new cleaner rear derailleur
A new SPD pedal with a different cage and more cleat support
New front and rear shifters that felt crisp and light during shifting
A new brake caliper that look similar to the new XTR
Setup is available in single, double and triple configurations. The side pull front derailleur delivers serious power with reduced effort–almost as little effort as a rear shift. With front shifting so precise, it’s no wonder Shimano doesn’t want to give it up.
1x Option The single ring version of the XT drivetrain uses what Shimano calls Dynamic Chain Engagement (DCE), a tooth shape that supposedly results in a 150% increase in chain retention. This isn’t a narrow-wide design like the one employed by SRAM and a host of other chain ring manufacturers – it relies on a more squared off tooth profile that’s slightly hooked in order to keep the chain from popping off in rough terrain. The rings are available in 30, 32, and 34 tooth versions.
Not only does the side pull derailleur provide more leverage to increase power and cut down on shift effort, it takes up less space which allows more room for tire clearance. This may help the front derailleur survive in a world of shorter stays, bigger wheels and fatter tires.
Trickle Down
XT M8000 shares pretty much all the functionality of XTR, for less than half the price. The shifters have the same tactile feel and solid, well-defined clicks. The notable change from the 10-speed group is how solid each click is, which helps alleviate unwanted shifts.
The rear derailleur features an adjustable clutch, so you can tune the feel and and performance to suit your trails and riding style. If you ride smoother terrain you can lower the clutch tension and reduce shifting effort, or you can increase clutch tension for a quieter ride and improved chain retention.
The rear derailleur can use Shimano’s direct mount, as seen here, but also can be installed on a conventional mount. Shifting was fast and precise, as one would expect from the legendary Deore XT name.
The 11-40-tooth cassette itself doesn’t have as much range as a SRAM 10-42, but it’s really designed to be run with multiple rings up front. The cassette provides closer gear steps than SRAM’s system so you can always pedal at a comfortable cadence.
The new XT brakes are a huge improvement, both in looks and power delivery. Again, they borrow from XTR and share the same clamp, one-piece master, and matching lever blade. To address complaints, Shimano also made the brakes a bit less grabby, which is instantly noticeable. Total power feels good, but it’s easier to control without locking the wheel up.
I-Spec has changes as well. To mate the brake levers and shifters to the same clamp, the brake clamp simply wraps around the shift mount to hold it in place. It’s nice and clean, but the new clamp needs to be run quite tight to prevent the brake and shifter from flexing a lot during use. This is fine unless you’re used to running your brake clamps loose enough so they’ll rotate on the bar instead of bend during a crash.
