Compatibility & fit

Fits tyres marked 26 x 1.9/2.125. Check the size printed on your tyre's sidewall, and make sure your rim's valve hole and your pump head suit a Schrader valve. Our workshop can fit tubes and tyres if you'd rather leave it to us.

Covered against manufacturing defects in materials and workmanship. Normal wear, punctures 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, CST's Australian distributor.
