January seems very early in the year to be seeing photos of next year’s products. Leaks like this seem to get earlier every year. The first image shows a redesigned Sram X0 groupset with many trickle down XX features including a double crankset and 10spd cassette. The second image shows a redesigned Shimano XTR groupset with double and triple crankset options and a 10spd cassette. It must be hard to make an already beautiful product even more beautiful, but the chrome XTR crankset looks stunning. There's also a Shimano parts list showing a number of new XT and SLX level 10spd components including rear derailleurs, chains and cassettes.
