Today SRAM announced their new line of Boost 148 products. The details are laid out below.
DRIVETRAIN
[Press Release] The Boost system’s crankset utilizes front chainrings that sit a corresponding 3mm outward to ensure the required chainline, but Q-factor is completely unaffected. A major benefit to the repositioned chainring is increased clearance, which allows more options for tire choice and rear-end designs.
Boost technology can be available at the following premium and performance levels
(24mm spindle only).

AVAILABLE (24mm spindle)
• XX1
• X1 1400
Note: boost cranks can only be used when paired with a 148mm hub
BOOST 148 COMPATIBLE COMPONENTS
XX1 CRANK
Developed for maximum chain control, each tooth’s thickness is precisely CNC-machined to support the chain’s inner and outer links perfectly.

• X-SYNC™ tooth profile provides maximum chain control
• Carbon arms with forged aluminum spider
• CNC- X-SYNC™ Direct Mount ring
• BOOST option
• Wide/narrow Q-factor cranks for BB30 and GXP
Note: boost cranks can only be used when paired with a 148mm hub

X1 1400 CRANK
Quality and durability combine in the SRAM X1 crankset to deliver consistent performance every time out. Featuring SRAM’s X-SYNC™ tooth profile, the X1 crankset is engineered for complete chain control. Each tooth’s thickness is CNC- machined to work seamlessly with the chain’s inner and outer links.

COMPLETE SYSTEM
BOOST 148 REAR WHEELS AND HUBS
REAR WHEELS
Much more than a new, wider axle standard, the Boost system uses a rear hub that is 6mm wider than a 142mm design—each flange is 3mm farther from center. The greater flange offset allows a stronger spoke-bracing angle resulting in a stiffer wheel. Given the same rim and spoke spec, a 29″ Boost wheel will have the same stiffness as a 27.5″ wheel built on a 142mm hub.
COMPLETE SYSTEM
BOOST 110 FRONT WHEELS AND HUBS
FRONT WHEELS
The Boost system uses a front hub that is 10mm wider than a 100mm design—each flange is 5mm farther from center. The greater flange offset allows a stronger spoke-bracing angle resulting in a stiffer wheel. Given the same rim and spoke spec, a 29” wheel built with a 15×110 Boost hub becomes as stiff as a 26″ wheel built with a standard 15×100 hub.

X0 HUB
Finally, a hub worthy of the X0 name. Built to roll over the toughest mountain terrain, the SRAM X0 Hub proves that being solid doesn’t mean being sluggish.
DOUBLE TIME™ ratchet design gives you smooth 6.9-degree engagement—all whilekeeping everything light and steady. Super-precise SPEEDBALL™ bearings mean lower resistance, faster revolutions and no more time spent readjusting play. From pawl tooth to side cap, we went the extra mile on the X0 Hub—so you have less to worry about on the trail.
