I sold most of my Silcas, except for the painted to match Silca pumps on my Chris Kvales.
After I tried the Lezyne Micro Floor Drive HPG I won't go back.
This is
small enough to be carried in a handlebar bag or in my tool roll on the saddle.
Will pump high pressure much more quickly and efficiently.
The HPG model has a built in gauge.
First line of defense is a good co2 system though, such as the Lezyne with the flex hose.
I always have that in my tool roll with sufficient large capacity cartridges for high volume mtb tires, such as the Maxxis 29er tires I am using.
