Very solid, German made pump, with all of the features you'd expect and then some:
- comes with multiple adapters so you can do older SIDs, RS IFPs', Zokes air forks etc;
- pressure release valve, which is much better than the release button seen on other pumps;
- high accuracy gauge;
- all metal contruction;
- low loss air connector, so very little pressure is lost for the shock/fork air spring when disconnecting the pump;
- very reasonable price
when you factor in the quality of construction and the range of adapters that come with it.
