On my Interstate I carry a small hand pump and always use it to top up the shocks, under a dozen strokes are needed... maybe 10 times that to top up the tires a few pounds if a compressor isn't available. Mine's perfect for the shocks but being much smaller than a regular pump I would use it for the tire only in an emergency.Wonder if anyone still uses the old manual pumps. I was thinking abou buying one... No battery needed. Kinda old school nostalgic too.
