About the Aspen

The Aspen is one of Maxxis's premier cross-country race tyres. A low centre tread keeps it rolling quickly, while side knobs that are substantial for an XC tyre give cornering traction. Maxxis recommends it for dry to mixed XC trail conditions, front or rear, and reserves the 170 TPI casing for its lightest Team Spec models.

MaxxSpeed rubber and EXO casing

MaxxSpeed (2023) is Maxxis's top XC race compound. Its high-silica formula improves wet traction and, in Maxxis lab tests, cut rolling resistance by about 25% against 3C MaxxSpeed. EXO adds a light, flexible, cut- and abrasion-resistant fabric to the sidewalls. The 170 TPI Team Spec casing is Maxxis's ultra-light XC build.

Compatibility & fit

Fits 29-inch rims (ETRTO 57-622); Maxxis lists a 17–30 mm internal rim width. Maximum pressure is 50 psi. Check frame and fork clearance for a 2.25-inch tyre. Fitting isn't included; our workshop can mount it and set it up tubeless.

Covered against manufacturing defects in materials and workmanship. Normal tread wear, punctures, cuts and damage from incorrect fitting or inflation are not manufacturing defects. For warranty support, return the product to Tune Cycles and we'll manage the claim with KWT Imports, Maxxis's Australian distributor.
