Earlier this week the news of Shimano’s updated XT group hit. You can read similar versions of the same press release here and here and here.

But what does this all mean to you? And more importantly, what parts of this technology will trickle down the line to the benefit of all?

In my opinion, there are a few highlights worth taking a closer look at.

Rear Deraileur

The low-profile “Shadow” rear derailleur is clearly the most interesting development of the new XT group. By separating the pivot from the mounting bolt, Shimano was able to move the parallelogram of the rear derailleur inboard, making the whole system tuck into the bike on the inside of the quick release skewer. Vertical movement of the system towards the chainstay has also been altered in an effort to reduce noise over rough terrain. In practice these changes should add up to a longer lasting derailleur less prone to crash damage. Hopefully this same feature will help keep rear hangers better aligned as well, leading to more precise shifts all around. Assuming this derailleur works, I’d expect to see it trickle down the Shimano mountain line pretty quickly.

Front Deraileur

Increased versatility is the big deal here, with one derailleur compatible with 28.6, 31.8 and 34.9mm seatubes and both top- and downtube cable routing. This should help make the parts bin easier to sort through, and take some of the mystery out of front derailleur model differences.

Brake Levers

While the claimed increased power of the new XT system will be sought after by some, the independently adjustable reach and free-stroke range before pad engagement should lead to improved brake ergonomics for all manner of hand sizes. And when Shimano introduces features like this, it’s only a matter of time before brake manufacturers across the board adopt the idea.

What will it cost? When will it trickle down to LX and Deore levels? My crystal ball is out of service today, but I’d reckon a) More than last year, and b) In the next riding season or two.
