Commonly known as Easton's flyweight XC race wheel, the Easton EC70XC Mountain Front Wheel boasts a 20mm internal rim, so it'll really shine on singletrack, from XC racing to all-mountain shredding. Carbon fiber rim rolls smooth and quiet over the roughest terrain, plus carbon offers greater impact resistance over aluminum. Versatile 20mm internal rim easily fits tires up to 2.4" for more surface traction on tough trails. 24 straight-pull, double-butted spokes are laced to Easton's M1 hub and sealed cartridge bearings keep the EC70XC spinning smooth and trouble-free. Entirely hand built and acoustically tuned, this wheel stays straight and true longer.
