Frequently asked questions
26", 27.5" and 29", all for 1.9 to 2.5" tires. Each size has its own tube length (1,865, 1,975 and 2,080 mm).
76 g for the 26", 80 g for the 27.5" and 84 g for the 29". Over 150 g less per wheel than a 235 g butyl tube.
Yes. It's fine over tubeless sealant residue on the rim and compatible with disc and rim brakes. Folded, it's very compact to carry as a spare in your saddle bag.
Yes, and so are the 27.5 and 26: a 45 mm Presta in every size, 100 % metal, black anti-corrosion anodized and with a removable core.
Pre-inflate the tube to 20–30 % (max. 7 PSI) so it takes shape, insert the valve into the rim, place the tube evenly inside the tire and finish inflating to the recommended pressure. Don't inflate it outside the tire or use metal tire levers.
