## Description

For all the talk of the XX Cassette, the XX Crankset is really where they're changing the gearing paradigm. Double chain ring cranks have made consistent if periodic appearances in the MTB world for years. The reasons for their appearance have always been the same -- lighter weight, better Q-factor, better chain line, faster shifting, and no chain suck. Ritchey was the last to push 2x9 gearing starting back in 1997, and that was an era of seven and eight-speed cassettes. With nine-speed making its way into mountain bikes, 2x9 made sense for places without steep terrain.XX isn't Tom's 2x9. For one, with XX you still get the super-wide range you'd otherwise get with 3x9. For another, unlike Ritchey, they're designing the entire system rather than making a few pieces, then hacking designs for the rest.XX cranks are optimized for the 2x10 system. The only given was using two rings and a through-axle spindle. They went to the drawing board to re-imagine the rest. Looking at it, you know the crank is different -- different in a more profound way than even XTR. Both chain rings are affixed on the inside of the crankarm. This helps keep the q-factor down as well as keeping the chainline narrow, at 49.5mm. The outer ring has a 120mm bolt circle diameter while the inner has a 80mm bcd. These numbers seem odd, except that the outer was designed to work with 39, 42, and 45 tooth chain rings. The inner was designed to work with 26, 28, and 30 tooth chain rings. The exclusivity is a problem if you're trying to match the crank with any other shifting, but it's a benefit if you want XX. The benefit is that with less metal reaching from the chain ring teeth to the spider, there will be less flex, and faster response when pedaling. They also made the support area of the chain rings wider, out to 6mm, wider than other chain rings on the market. More meat means greater stiffness. And with 7075-T6 aluminum as the material, they're also pretty damn light.
