Hi Road.cc readers,
I'm keen to hear your thoughts on a clever new type of bicycle pump, that I have just launched on Kickstarter (and has been awarded “Staff pick”)
https://www.kickstarter.com/projects/crankpump/crankpump-the-invisible-b...
It's called CrankPump and it's a CO2 pump that lives in the hollow axle of cranks.
The idea is that it's a fit-and-forget replacement for the standard plastic cap on Shimano cranks. It also has a set of "TyreZip" levers that are pretty interesting.
Please let me know what you think.

Interesting idea but to me if you also are going to have to carry an inner tube or repair kit and if you are anything like me i'd like at least one spare co2 cartridge and i'm really quite happy with none too fiddly tyre levers,Then i can't really see it being much of an advantage over a small saddle bag in which i can also fit a multi tool and my lights.
You've given me an idea where to hide some emergency polos though.

Thats really neat. Its a good partial solution but still need a tube and possibly a multi tool along for the ride as ratfink says so in some ways is solving a problem that doesn't exist. Good luck though. The TyreZips are good on their own as well

I read that as 'Crack Pump'. Is there an alternative market?

For some people, not having to carry a pump and levers in your saddle-bag is a small advantage that lets you carry another gel or use a smaller saddle bag. For other people, it lets them get rid of their saddle-bag entirely, by stuffing a spare tube under the seat. If you're going to carry a CO2 pump and levers, then it's gear to carry them somewhere neat that you never need to think about.

It's a Softride Rocket - they stopped making them a whole ago, but they are great bikes that start conversations.
