SPANK 350 VIBROCORE BOOST 27. 5" WHEELJUST VIBIN'Wheels are an integral part of your mountain bike. The type of wheels you use has a significant impact on your performance and ride quality. The Spank 350 Vibrocore Boost 27. 5" Wheel is a high-performance wheel with internal vibration damping for DH and freeride. The rims feature a unique profile with a low sectional profile height and wide width. This adds radial compliance while also keeping a high lateral stiffness. With improved radial compliance, you'll have better traction over bumps and chatter, while reducing negative feedback. The rims also feature a Vibrocore inner well that reduces vibrations for a smoother ride and less fatigue. The rims are tubeless-ready for a smoother ride, better traction, and fewer flats.
