Performance & Use
A robust, dependable road tube for everyday riding and training. Continental's seamless construction and mould-cured vulcanisation give uniform roundness and reliable air retention, avoiding the flaws and seams that lead to failures.
Sizes & Fitment
Fits 700c road tyres from 20-25mm and 25-32mm, with a claimed weight of around 139g. Presta valve, available in 42mm, 60mm and 80mm lengths - the deeper valves suit deeper-section rims. Select the size and valve length for your wheels.
Inner tubes are supposed to hold air in. These do just that. Conti stuff is good. Roll well and dont cause too much friction between the tyre and the rim. Even better with the addition of some talc in the tyre before assembly. See to be pretty tough too Recommended.

Hello, This will fit the front wheel, however, you will require an 80mm tube for the rear wheel. Many Thanks Liam
Hi These will fit a 28mm tyre no problem, only small issue being that the inner tube will have to stretch a little more than a 25 tyre so there will be a minutely small difference in the cross sectional thickness of the tube once inflated to 28 mm tyre width. I use them no problem as I cant find a 28mm tube with an 80mm presta valve... long story short = use them no problem just carry a couple of spares :)
Hi Palm, These will be too narrow for a 28mm tyre I'm afraid, Many thanks Joe W
Hi Seth, You would require 80mm valves for your wheels. https://www.sigmasports.com/item/Continental/R28-Light-700-x-20-25C-Presta-80mm-Valve-Inner-Tube/HAAV Many Thanks Liam
