The CYDY TPU 24x1-1/8 to 1-3/8 (520) inch inner tube has red and white packaging, fits BMX bikes with tire sizes 24 x 1-1/8 to 1-3/8, includes product specs, weight info, and features a Presta valve for easy inflation.

Description

A 32 gram TPU inner tube for 24 inch wheels, made to suit 24 x 1-1/8 and 24 x 1-3/8 tyres, ETRTO 25-520 to 40-520. It runs a Presta (French) valve with a 45mm stem, and maximum inflation is set by your tyre's pressure rating.

Fit it carefully: this tube cannot be inflated much outside the tyre without irreversible damage. Use a manual pump rather than a compressor, turn the valve inward, and add a small amount of air, under 0.5 bar (8 psi), until the tube is round before seating the tyre. On rims with a no-ring-lip system to ISO/TC 31, do not exceed 5 bar (72 psi).

Features

32 grams on the scales. TPU construction brings the tube down to 32 grams, so a spare is easy to carry in a pocket.
Fits 24 x 1-1/8 to 1-3/8. It covers ETRTO sizes 25-520 through 40-520, so it suits the common 520 tyre widths.
45mm Presta valve. The Presta, or French, valve has a 45mm stem, which suits standard depth 24 inch rims.
Inflate inside the tyre only. Pumping this tube up outside the tyre causes irreversible damage, so seat it with a small amount of air first.
Hand pump, not a compressor. Use a manual pump rather than a compressor or other high speed air filling equipment.
