20 to 29" x 1.95 to 2.50" linear air chamber
The linear air chamber is very useful for quickly repairing a puncture on a bike where removing the wheel is "complicated". This is the case for electric bicycles equipped with an in-wheel motor or bikes with rollerbrake or gear hub brakes.
Linear or straight design of the air chamber, as opposed to the conventional closed air chamber, facilitates quick replacement without requiring removal of the wheel from the bicycle.
A single linear tube can accommodate different tyre sizes from 20'' to 29'''.
The ends of the air chamber overlap to create a circular air chamber that fills the tire, eliminating the need to completely remove the wheel; simply unclip one side of the tire and insert the linear air chamber into it.
