(google translate)For 2014 SRAM offers a complete single crown more suitable, such as price, to the pockets of the end customer even if there is to say remains a product for the agonist and by deriving from the SRAM X0 is a High Rate range, lower weight as the Shimano XTR double.
The technology is identical to the SRAM XX1 with 11 speed rear (10-42) and the ability to change the front crown gear ratios deciding appropriate to their athletic ability. According to some indiscretion of the cassette Sram 11v X01 weighs 280gr against 260gr of XX1 (the case of the 10s Shimano XTR weighs 265gr), a difference is not abysmal whereas the cassette XX1 is proposed to 355 € List! From here you can understand why many people have felt the need of a group of relatively less researched Sram XX1 to limit a bit 'prices, especially in repair and maintenance. The construction material is aluminum, which in both XX1 and X01, with the same coupling system to the wheel through the bodice XD.
There are substantial differences in the crank whose construction is aluminum (instead of carbon as XX1). The weight is 800 grams (XX1 650gr - 750gr XTR). The Spider is different compared to the X1 but the replacement of the crown is always done without disassembling the entire crankset.
The command trigger is aluminum (carbon in XX1) and is also available command GripShift. The chain is the same of XX1. Investigating a bit 'on the weights of members of the group Sram X01 should weigh approximately 200g more of XX1, then a product a bit' heavier, more durable and naturally cheaper (prices and official weights Verrano made available at the end of 2013).
