Rock Razor Addix Tire

Schwalbe's Rock Razor Addix Tire - 29in is built for the racer. Its sturdy side knobs flanks a smaller, lower profile center tread that lets this tire fly over dry hard packed trails and while still able to have the cornering chops to dig in and provide confidence at high speed. The Rock Razor is designed primarily as a rear tire and it'll save the legs when pedaling between stages and inject speed during enduros, or if you are looking for an advantage on a quick, sunbaked DH course.

The new Addix compounds represent many hours of research and development and money Schwalbe spent refining the formulas. The fruits of their labor include increased grip, faster rolling, and better durability. That all adds up to more fun on the trail. This SpeedGrip compound replaces the all-around PaceStar version and, like the tread, its fast when you want it and grippy when you need it. Snakeskin TL Easy promises that the tire sets up tubeless hassle-free and the sidewalls are durable enough, you won't think twice hucking blind into a rock garden at speed.

  • A semi-slick tire made for speed without sacrificing grip
  • Low-profile, closely-spaced center knobs are quick on hardpack
  • Aggressive side lugs offer excellent cornering traction
  • SnakeSkin reinforced sidewalls for fewer flats
  • SpeedGrip compound rolls quickly while still grippy
  • Item #SCH003B

I'm pretty easy on tires. 29x2.35 Addix. Fast tire, but not substantially faster than a Nobby Nic. Corners very well on the back, and grips well climbing in the Wasatch Back. After about 4 hard rides I tore off a side knob. I'll stick with the Nobby Nic on the back, as it can be rotated to the front as well. I would not be inclined to do that with the Rock Razor. I could recommend it, if the terrain is easier on tires, such as loamy conditions. Edit: For marcg611, I'll post a review on it. I thought I had already.

Hey.. saw you commented on the Maxxis 2.6 Rekons but I couldn't comment there. How did you like them mounted on the 27ID wheels? Is the profile not too round and do they corner properly? I really appreciate any feedback

Fast tire with cornering ablities

Love this as a rear tire. Great rolling resistance, but it still has the cornering knobs to help me through the corners. Might not have the same braking traction as a tire with beefier center knobs, but I am usually not riding something super steep when I have this tire on.
