Shimano launches new XT Dynasys Groupset

XT features trickle down technology from last years XTR revamp.

Mountain Bikers who have been wanting to upgrade their drivetrain to new 10-speed technology but have been reluctant due to sticker shock, the wait is over. Shimano's new XT Dynasys system offers all the benefits of their high-end XTR group but at a fraction of the cost (and a little added weight).

So how does it ride? Well, to be quite honest. It feels very similar to the current XTR group, almost identical. Shifting was distinctly Shimano, crisp and smooth needing very little effort. Shifting through multiple gears in one shift with XT is also surprisingly easy and quick making those unexpected steep climbs easy to gear down for.

With the brakes being the biggest change for the group, it was also the most noticeable. Lever design is spot on for excellent one finger braking and the tool less lever adjust makes finding the perfect lever placement headache free. Power increase with the new brakes is very noticeable. Power matches that of the XTR trail brakes (one of the most powerful brakes I have ridden), with amazing heat management on long descents. With only a little squealing after creek crossings, our test brakes with metal pads, were remarkably quiet.

Two chainring setup options will make XT more appealing to those looking to go with either a 2x or 3x system depending on their specific use. Chainring options will include 40/28t and 38/26t in the double and 42/32/24t in the triple. With new Dynasys technology that offers a tighter gear range, the triple setup shifted surprisingly smooth even under substantial load. We have yet to ride the double set up for XT yet, so stay tuned for that later.

Another big and needed change can be found in the pedals, with two distinct options available, trail and race. We were able to spend a good amount of time on the trail pedals, and although skeptical at first, the trail pedals offered an incredible amount of additional support over previous XT pedals. The race pedals also see an updated design providing a larger platform without the added material of the trail pedal.

Revamped wheels offered in two rim widths, you guessed it, trail or race. Both wheels feature updated rim and hubs and are offered in the most popular configurations. Another huge benefit to these wheels is that they are full UST tubeless, meaning no rim strips or tape to deal with.

So its true, good things do come to those who wait. If you were impressed with the new generation of XTR, but couldn’t stomach the cost, you will be happy to see the trickle down of features through the XT line. Powerful brakes, smooth shifting drivetrain, updated pedals, and full UST wheels make the 2012 XT group a full course meal at the price of fast food.
