Unbranded Presta Long Valve Bike Inner Tubes - 700 X 35/43c (Fits 36-42mm)

This is a brand new, unbranded bicycle inner tube, sized 700 x 35/43c.

That means it fits tires with a width ranging from about 35mm to 43mm (so 36, 37, 38, 39, 40, 41, 42mm are all good).

It features a Presta long valve, which is the slim valve often found on road bikes and higher-end hybrids.

It's made of black rubber and is a universal fit for bikes that use 700c wheels with those widths.

Keep a spare on hand for when you get a flat.

Reliable and simple, these tubes will get you back on the road.
