The SRAM NX crank is with its Eagle design and the known performance our latest addition to the Eagle Ecosystem. With the SRAM X-SYNC-2 chainrings, the NX crank guarantees optimal chain control. For an efficient, safe and silent operation with the SRAM chain links, each individual tooth has been precisely designed and manufactured in shape and strength. The DUB technology offers an advanced bottom bracket and completely new crank axle design. Together they result in a unified approach to the topic of bottom bracket shell standard, a better seal against contamination and full forward and backward compatibility. DUB is now the new benchmark in performance and durability.X-Sync 2X-SYNC 2 EAGLE is the latest development of our SRAM X-SYNC technology. The tooth profile of the chainring increases the chain tension and efficiency when pedaling. The life of the chainring is higher because the X-SYNC EAGLE technology reduces friction and dirt.DUBThe unit of crankshaft and bottom bracket is the heart of the DUB technology. This is where stiffness meets durability. SRAM has gone an unconventional step further and has made everything even simpler, with the better integration of chainring, crank, shaft and bottom bracket in this clear, systematic approach means better drive performance. - Intended use: MTB - Details: - Compatible with all Eagle drive systems - Compatible bottom bracket: DUB BSA 73, DUB PF 89.5, DUB PF 92, DUB PF 30, DUB MTB 73, DUB BB 30, DUB MTB 73 - Weight: 705 g (at 172 mm, 32 teeth) Material - Crank arm(s): aluminum 7000 - Large chainring: steel Scope of delivery - Scope of delivery: 1 crankset SRAM NX Eagle DUB Boost (chain not included) Chainrings - Number of chainrings: 1 chainring - Gear ratio: 32 teeth Crank - Bolt circle: without bolt circle mm - Bolt circle type: Boost - Chainline: 52 mm - Rear derailleur compatibility: 11-speed - Type: Direct Mount - Axle mount: DUB (28.8 mm)
