Now you can fine tune pressures out on the cyclocross course rather than head for the pits during your pre-ride. You can repair punctures with 0.5psi accuracy whether you're in your garage, your hotel room or trailside on the Great Divide. Never again fly with a floor pump, never again have to pinch your tire and guess.
In regards to accuracy, the problem with mini-pump gauges quickly becomes an issue of size. The gauge can't be so big that it feels bulky in a jersey pocket nor can it be too small. Much like a high-end watch, the internal mechanism of an accurate pump gauge consists of a variety of small, precision machined parts with precise movements. Also similar to a watch, the internal components of a floor pump gauge are already very small in size. As they looked at creating a gauge small enough to mount on a mini-pump, Silca found that as the overall size of the gauge decreased, the internal mechanism needed to be simplified and therefore accuracy decreased rapidly. This leaves traditional mini-pump gauges generally being barely more accurate than squeezing the tire with your fingers.
The other issue to overcome is durability. The TATTICO is designed to be small enough to fit in a jersey pocket but it's also able to be mounted alongside a bottle cage. When mounted, the mini-pump essentially becomes part of the frame so must be able to withstand high frequency vibrations, heavy impacts and also moisture and dirt intrusion from riding in adverse conditions. The only technology available today that can handle these conditions is wireless technology. The TATTICO BlueTooth® gauge is isolated in a fully sealed, shock-proof and waterproof environment within the pump body where it can be expected to perform flawlessly for many years.
