Compatibility, Size and Fit
This tube is aimed at 26 inch fat bike tyres in the 26 x 4.0 / 100-559 range. It is the right kind of part when the wheel, tyre and valve type all match. Check the valve opening, the tyre size marking and the rim size before choosing an offer.
What Else You May Need
A compatible fat bike tyre and a pump suitable for a Schrader valve are needed for fitting and inflation.
Before You Decide
Confirm the 26 x 4.0 and 100-559 sizing, the Schrader valve type and the single-tube quantity before choosing an offer. If your tyre or pump uses a different valve standard, this is not the right fit.
