Neumáticos Panaracer

Panaracer has been making tires in Japan since 1952, and the GravelKing has become the line that defines the brand in gravel cycling. Designed for mixed-surface riding — from hardpacked dirt and fire roads to loose gravel and light singletrack — the GravelKing lineup is built around matching tread pattern and casing construction to the terrain, not just the wheel size. Panaracer’s GravelKing is also the named title sponsor of the UCI Gravel World Series through 2028.

The RA Cycles Panaracer collection centers on three GravelKing variants. The slick rolls fast on hardpack and tarmac. The SK (semi-knobby) adds bite for looser surfaces and corners. The SS (semi-slick) splits the difference for mixed-surface days. All three are available in tubeless-ready versions, with Plus models adding ProTite puncture protection. Both 700c and 650b wheel sizes are stocked, along with the Pasela ProTite clincher for road and urban use.
