SRAM X0 DH Rear Derailleur 


Downhill bikes require a certain amount of specific componentry due to their specialized nature. This SRAM X0 DH 10-Speed Rear Derailleur is just one great example. We sell a short cage X0 rear derailleur, so why this special DH version? This one is designed with a narrower range cassette in mind. On a true downhill bike, you'd want to run a 28t or smaller big cog on your cassette. As such, this derailleur is made to accommodate a max 28t cog.That said, there are geometrical differences between this DH derailleur and the standard short cage X0 unit. The angle of the parallelogram is more closely matched to the conical angle of the cassette. The performance advantage comes because the upper jockey wheel can more closely follow each cog in the cassette from small to large. The result is faster, more precise shifts when you need to be on the gas from one corner to the next. The inner and outer parallelogram linkages are forged from aluminum, polished, and clear anodized to protect the finish. They have wide pivots to ensure linkage stability when the derailleur is under tension in the biggest cogs. It's built specifically to accommodate the narrower 10-speed chain and up to a 36t cog and uses their Exact Actuation Technology to match X0 10-speed shifters. While their 9-speed groups have long relied on a 1:1 pull ratio, designed to be more tolerant of the muck and grit associated with mountain biking, the Exact Actuation in the 10-speed X0 group takes the performance to another level by ensuring a perfect and consistent shift distance between each gear, all the way across the cassette. And like the rest of SRAM rear derailleurs, the X0 model is designed for direct cable routing, eliminating the typical loop of excess housing necessary with other derailleurs.The SRAM X0 DH 10-Speed Rear Derailleur is designed to be used with a single front chainring and 10-speed cassettes with a max 28t big cog.
