Crank Brothers Gem Mini Pump
Lightweight mini pumps that are easily packable.
Despite the speed of CO2 inflators, a large portion of riders still trust their dependable mini pumps. The Crank Brothers Gem pumps were designed to be durable and easily packable. Available in short and long versions, the short version is compact enough to fit in a jersey pocket. The long version, while only slightly longer, will require fewer pumps to inflate a tyre. Both versions feature a reversible head for Presta/Schrader valves and have a max PSI of 100.
- Long (205mm), Short (176mm).
- Long (155g), Short (131g).
- Compatible with both Presta and Schrader valves.
- Includes mount to fit to bottle cage bolts.

Well built and good price
Great little pump. Crank Bros make great stuff that looks good. Pump works well and is reasonably light.

mad emergency pump does inflate
by harry -
mad emergency pump does inflate tube to riding pressure very easy and fast when fitting new tube, once theres air in tube it does take allot of pumps to get the pressure to rise, but I only use it for breakdowns so perfect for that. very well sized fits perfectly in camel back and very very light, awesome pump imo

It's made by Crank Brothers, It's a mini-pump, and boy is it a gem! Even with the smallest size, the pump extends to an amazing size, letting you inflate tubes with speed and style! From personal experience, you can inflate a 29 tire in under 2 minutes. The overall build is with high quality and even the plastic parts feel solid, yet surprisingly light. The helpful high pressure/low pressure switch at the bottom is very handy! It fits in a jersey pocket with ease and takes up very little space in a Camel Back or similar. The ONLY DOWNSIDE is that the included bike mount rattles when in use. The holder does indeed hold the pump very tightly so it wont fall out when you're out on the trail, but ,on my bike at least (Norco Fluid fs 1), it doesn't hold the pump far enough out to stop small vibrations from causing rattling. I don't believe it could do any long term damage to a bike frame, but still an annoyance and an off-put for riders that like mounting their pumps to their bikes.
Not yet had to use.

Not yet had to use. Is good length and seems well made. Diameter is bigger than expected: fatter than other pumps, perhaps that will be useful when I have to use it.

Awesome pump, only really had a few flats and popped tubes on the jump bike. Gets me back on and hitting the trails pretty quickly.
