This certainly keeps the whole tube changing operation as ?pain-free as possible.

With ?its minimal package, the Injector-Pro takes up little pocket space (cue panic thinking we'd forgotten it), has a good seal on the valve and sticks a lot less than others we've tested before.

The trigger application is great for achieving ideal pressure instead of the usual hit-and-miss affair often associated with canisters.

Hannah is Cycling Weekly’s longest-serving tech writer, having started with the magazine back in 2011. She has covered all things technical for both print and digital over multiple seasons representing CW at spring Classics, and Grand Tours and all races in between.

Hannah was a successful road and track racer herself, competing in UCI races all over Europe as well as in China, Pakistan and New Zealand.

For fun, she's ridden LEJOG unaided, a lap of Majorca in a day, won a 24-hour mountain bike race and tackled famous mountain passes in the French Alps, Pyrenees, Dolomites and Himalayas.

She lives just outside the Peak District National Park near Manchester UK with her partner, daughter and a small but beautifully formed bike collection.
