The Spank Industries 350 Vibrocore Rim features a unique profile with low sectional profile height and wide width improves radial compliance, resulting in reduced deflection and better traction over bumps and chatter, while remaining stiff laterally for cornering performance. 

To increase durability and improve vibration damping and reduce handpump on big days of riding, Spank injects a hard-cell foam into the hollow rim. The low density, pressurized core performs a similar function to the soft tissue inside bones, increasing inner wall strength and absorbing vibrations.

  • Unique profile with low sectional profile height and wide width, which adds radial compliance, while keeping high lateral stiffness.
  • Improved radial compliance for better traction over bumps and chatter, while reducing negative feedback to the rider. Performance and comfort enhanced.
  • Vibrocore™ inner well, reduces the transmission of harmful vibration frequencies, meaning less vibration for the suspension and rider, also increasing the fatigue life of the rim.
  • 30mm internal width is extremely versatile, fitting tires from 2.0” to 2.6” perfectly, and even allowing + size tire use, without negative squaring off of tire profiles.

Formerly known as the SPIKE 350 Vibrocore rim, the 350 Vibrocore rim is ideal for DH, Enduro and Freeride applications, as well as hard-hitting trail riders looking for maximum downhill performance.

Reviews — what the media is saying about the Spank 350 Vibrocore rims

Pinkbike — "The Vibrocore guts don't make this rim indestructible, but they did brush off the kind of abuse that claimed a handful of other rims over prior months. " — Mike Levy

Mountain Bike Action — "The Spank Spike 350 Vibrocore wheels proved they can take a beating and keep rolling. They managed to smooth out the trails a bit and increased our confidence due to their ability to stay on line and not be deflected by ruts or rocks."

VitalMTB — "During back-to-back runs, our baseline set of alloy wheels became battered and dented and lost their ability to hold a bead. The Spikes never flinched, even with multiple rim strikes. The durability combined with a relatively light weight make the Spike 350 a viable wheelset for either heavy trail use or downhill without even considering the unique, foamy guts." — Brad Howell

Bike Radar — "Traction was also better in high-load cornering or successive-hit situations than with most wheels, it was as though I was running a particularly well-damped tyre carcass or had hit a sweet spot with my suspension tune." — Guy Kesteven
