Featuring SRAM’s X-SYNC™ tooth profile, the GX chainset is engineered for complete chain control. Each tooth’s thickness is CNC machined to work seamlessly with the chain’s inner & outer links. & with five available chainrings, you can personalise your gear range to match the way you ride. BOOST148 BOOST148 (hub width 148mm x 12mm) is targeted at 29ers & is designed to increase wheel stiffness via the hub. The hub flanges are slightly wider apart from standard hubs (142mm x 12mm) & according to SRAM & Trek "this small increase in width results in significant gains to rear wheel stiffness — comparable to a 27.5in mountain bike wheel". ...

Whether you're shredding the trails with your friends or exploring new routes on your own, this rear mech is engineered for smooth shifting performance. It features a hard-wearing aluminium cage construction, which makes it more than capable of handling all the abuse that's associated with all-day epics in the mountains. SRAM has also equipped this model with steel pulley bearings for an additional layer of robustness. Coming complete with X-Glide shifting & race-bred technologies, this model will boost your confidence in all types of terrain conditions. Technologies: Direct Route: Here's the dirt on middlemen: they suck. That's why Direct Route Technology™ doesn't have one. Instead, the cable routes directly to the actuation mechanism. Result? Less friction. Less effort. More oomph. Plus it's impervious to cable housing damage. Exact Actuation: When we launched our road technology from scratch we reapplied our MTB proven SRAM 1:1 actuation ratio (shifter cable travel: derailleur movement). Exact Actuation helps to simplify & stabilize the uneasy act of balancing rear derailleur hanger design, tight cog spacing, & exact cable tension. ...
