Please refer to the charts below to determine which versions are available with SG2. - Nylon fibers have a flat profile, which reduces the amount of rubber needed to fill the gaps between fibers and minimizes weight. - Protected SG2 gravel tires feature a 120tpi casing, which improves suppleness compared to a traditional 60tpi tire. - SG2 was specifically designed to be a puncture protection layer, but it also improves air retention and eliminates seeping at the sidewall.

Raddler is an excellent choice for loose terrain where traction takes priority, but efficiency is never far behind. Lean it over, take the inside line, brake late, and stay pinned with the Raddler.
