What Our Gearhead(R) Experts Are Saying:"The Turbine SL is the wheel I point people toward when they want a real performance upgrade without going full carbon. The Vault hub engagement is noticeably fast, which you feel most when you're pumping through a technical section and need the drivetrain to respond right now. The 25mm internal width is the sweet spot for 29er trail tires, and the offset spoke lacing keeps everything balanced and stiff without adding weight."There's a moment on a fast XC line when the trail starts asking questions, and your wheels either answer them or don't. The Race Face Turbine SL 25 29in Boost Wheel is built for the riders who need a confident answer every time. These wheels slot into Boost-spacing bikes and deliver the kind of stiffness and responsiveness that makes a trail feel familiar instead of unpredictable. The 6069 alloy rim is welded, tubeless-ready, and built to handle rock gardens and rough landings without becoming a project. Offset spoke beds and double-butted straight-pull spokes keep the wheel balanced and tracking true through the kind of riding that wears out lesser builds. The Vault hub runs 3-degree engagement, so when the trail opens up and you start putting power down, the drivetrain picks it up immediately.
