Блок передних звезд SRAM GX Eagle Boost 148 DUB 1x12-speed 32T

This GX Eagle crankset by SRAM with direct mount and forged aluminum cranks is designed for Boost frames in conjunction with a 12-speed drivetrain. With the DUB technology, the crank optimally interacts with the DUB bottom brackets and thus reliably delivers constant, harmonious performance. Each Eagle chainring can be mounted quickly and easily on the direct mount bracket. The material thickness of each individual tooth has been precisely thought out and the chainring also interlocks perfectly with the chain thanks to the X-Sync 2™ tooth profile. You give everything on every ride and don’t want to worry? Then the GX Eagle Boost crankset is made for you!

Technology:

X-Sync 2™: X-Sync 2™ is the latest development in X-Sync technology. The high, angular and at the same time narrow tooth profile of the chainring with rounded edges increases chain tension and efficiency when pedalling. The life of the chainring is longer because X-Sync 2™ reduces friction and the accumulation of dirt.

DUB: The unit of crankshaft and bottom bracket is the heart of the DUB technology. Stiffness meets durability. SRAM has gone a step further and made everything even easier and better. It is the system approach through the integration of chainring, crank, shaft and bottom bracket that is decisive for better drivetrain performance.
