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.

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

SRAM_MTB_ROAM_40_Rear_Dynamic_Silver_MH

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

SRAM_MTB_ROAM_40_Front_Dynamic_Silver_MH

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.
