I noticed an advert for a Topeak Hybrid Rocket in CW this week. It combines a CO2 inflator with a mini-pump.

A great idea in theory, but does it work in practice? Is it the best of both worlds, or the worst of both worlds? The idea of it really appeals for my road bike where I like everything kept to a minimum.

Just buy a topeak pocket rocket and save on CO2 cartridges. Excellent pump. Have one on the commuter and one for rear pocket duties.

got one of these.. controllable co2 flow and a good sturdy pump as well.

Can you get both of those pumps up to around 100 psi okay?

My topeak will get above 100psi. Takes a while, mind.

I have the Canyon combined jobby, it’s great bit of kit.

I have a older combined pump. no idea who made it as the is no branding. Pump gets to a rideable pressure but that as it the CO2 inflator which works flawlessly I never have to pump. However I use tyres that punture easily so I rarely use CO2 either. They are a good idea as who CO2 cartidges do you carry and on a long ride you can get unlucky more than once. Also pressing a button and gettin 100 psi beats pumping especially in events.
