牙盘真心难看。。。

Shimano has been pushing hard with XTR to impress trail bike customers, spearheaded by ICE brakes, Shadow Plus clutch-damped rear derailleurs and most recently, the announcement of 29er-specific smaller chainring combinations. This time around, however, Shimano has apparently refocused is attention to XTR's cross-country roots. The announcement, while not earth shattering for PB's DH and trail majority, should make coss-country weight weenies blush. Shimano has figured out how to produce brake calipers and perches from lightweight magnesium alloy,peppered the brakes with titanium hardware, and then and added cooling fins (a-la Saint), to XTR brake rotors that promise to reduce peak temperature up to 40 degrees Fahrenheit. Better heat dissipation means that riders can choose the next smaller rotor diameter to save additional grams without too much concern for brake fade.
If there was any element of surprise, however, it was that Shimano will sell an XTR-level tubular wheelset replete with carbon fiber rims. Tubular rims have no flanges and use tires that are glued to the rim surface. Tubular tires are the only choice for professional road racers and have now gained a foothold in mountain bike XC racing. Among others, Scott's XC team has been on tubulars for almost five years - and because 29ers share the same rim sizes as road bikes, tubulars have been quite popular among big-wheel racers at all levels. The advantages of using such an archaic wheel and tire system are a much lower rolling resistance and an uncanny resistance to pinch flatting due to their lack of rim flanges. That said, tubular wheels are an odd offering from a corporation that has been conspicuously conservative in responding to trends. A single pair of carbon 650B hoops was airlifted from Japan for the Sea Otter - indicating that Shimano won't lag in its response to the mid-sized wheels, like it did for the 29er. All three sizes, 26, 27.5 and 29 inches, will be offered as the wheels come on line later this year.

The following is the official text from Shimano:
Press Release
Shimano’s 2014 XTR M980 series will see the addition of new lighter weight hydraulic disc brake components, new drivetrain components including a lighter bottom bracket and more durable chain, as well as ultra-lightweight carbon tubular 29” mountain bike wheels. The first mountain bike component range to have two separate complete groups – one for Race and one for Trail uses – Shimano XTR M980 introduced the Rider Tuned concept that allows riders to mix and match drivetrains, brake systems, wheels and pedals for the way they ride. For 2014, Shimano introduces new XTR Race products, specifically designed to reduce weight, increase efficiency and provide a winning edge for the world’s best cross country racers.
Lightest ever Shimano hydraulic disc brake system
Shimano debuts its lightest hydraulic disc brake system ever to the XTR line. Race rated to match the power and control of the M985 Race brake while dropping weight by 40g per wheel, the M987 disc brake will surpass rider expectations for a lightweight brake. Shimano engineers incorporated the use of a magnesium caliper and master cylinder construction in the new XTR BR-M987 to drop weight while maintaining system stiffness and control by properly managing heat. The new, lighter BL-M987 hydraulic disc brake lever lightens up thanks to carbon fiber lever blades and titanium fasteners. The BR-M987 caliper is compatible with ICE Technologies finned disc brake pads and the BL-M987 lever is I-spec compatible.
The SM-RT99 finned ICE Technologies disc brake rotor initially used on the World Cup downhill circuit is now available at the XTR level. Improving the heat absorbing capacity compared to theRT98 disc rotor through the addition of aluminium cooling fins between each spider arm, SMRT99 reduces heat by an additional 40 degrees. This new advanced ICE Technologies discrotor in smaller 180/160/140mm sizes, utilizes an aluminium rotor spider to increase braking efficiency and the rotor blade has a mud-shedding design.

Gluing tires onto tubular rims is nearly a lost art form in cycling. Shimano is definitely targeting its XTR Race Wheels at the pro-racer. Shimano reports that Schwalbe is making tubular XC tires. Geax also produces them.
Lightweight, durable drivetrain additions
The new premium level SM-BB93/SM-BB94 mountain bike bottom bracket will be added inthreaded and press-fit options that is lighter weight by 19 grams, offers lighter rotation andimproved sealing for the toughest conditions. For 2014, the new CN-M981 HG-X mountain bike chain uses Sil-Tec, an advanced surface plating technology to increase both performance and durability. Recently debuted in the Dura-Ace 9000 chain, Shimano Sil-Tec technology adds a low friction surface treatment that runs smoother and lasts longer. The new super narrow XTR CN-M981 HG-X chain with Sil-Tec better holds lubrication and sheds mud better than the previously unrivalled XTR CN-M980 chain.
