The Sunlite 26in Fat Bike Presta Tube is built for larger-volume 26 inch fat bike tires. These tubes cover 26 x 3.50, 26 x 4.00, and 26 x 4.50–4.80 tire sizes, all using ISO 559 fitment.
These tubes use 0.9mm wall thickness and Presta valves. Some versions use non-removable valve cores, so customers should select carefully based on tire size, valve style, and service preference.
