Crank Brothers' Sterling SG Pump features a tough aluminum barrel a little shy of 8 inches long for maximum pumping power; a switch to select high-volume (off-road tires) or high-pressure (road tires) inflation, and a handy built-in gauge. The universal head gets up to 100psi on either Schrader or Presta valves without having to switch the head.
The pull-out hose puts less stress on the valve. It's all very well hauling a giant pump around, but all that leverage can snap a delicate valve stem right off. This is a slimmer version of Blackburn's Core Pump that features a thread-on Presta-specific head with a short pull-out hose to give more options on where you pump from and fewer chances of your rippling muscles pulling the thing clean off. We weren't using that space in the barrel anyway, so the hose doesn't even affect the pump's efficiency. - Machined Presta valve core tool in the pump's base - Thread-on Presta valve on the extending flexible hose - Fits easily in jersey pocket or next to your bottle cage - 120 PSI - Weight: 104 grams
Our High Volume Boundary 1.5HV pump is designed for mountain bikers who need larger delivery of air for big tires. An extendable head means it's easier to pump, and the sealing lever doubles as a protective cover to keep it functioning no matter the conditions. The frame bracket has been optimized for recessed frame down tube. - High-volume construction optimized for mountain bikes - Innovative sealing lever doubles as protective head cover, protecting against water and dirt - Extractable head reduces the risk of damaging valve stem during inflation
