Pros: Cheap. Will eventually fill up your tire.

Cons: Hope you brought along a replacement arm or two once you finally have to use this thing. SLOW. No PSI gauge.

Recommendation: I had the misfortune of having to bum Goldengoose's pump several times while riding to fill up tubes. It takes FOREVER and you have to guess the PSI with the old squeeze test. Do yourself a favor and get a CO2 regulator or, better yet, go tubeless!

Pros: Sturdy design.
Lockon feature for the pump head.
Pumps up tires quickly for a hand pump.

Cons: None yet.

Recommendation: This pump easily gets my tires to 40 PSI.

Pros: very light
small size to fit in pack

Cons: no cage holder
no hose attachment

Recommendation: larger handle,
powerful for size

Pros: Great little pump that doesn't weigh a lot and doesn't break the bank

Cons: None

Recommendation: Like I said in the "pros" section: this little pump just does it's job. It won't weigh your pack down too much, it is small and compact, and the pricing is very reasonable at $20. This is a solid little handpump.

Pros: Small and light with decent volume. Can't beat a life time warranty!

Cons: Wobbles on Presta heads but that's easily remedied with proper hand placement. Wish it had a built in gauge to measure PSI kinda like the ones they make for cars.

Recommendation: A sweet little pump that gets the job done without taking 20 mintues out of your ride to pump the tire. A couple of tweaks to the design and this would easily be 5 star.

Pros: Lightweight, compact, and pumps tires up quickly without hassles.

Cons: None yet

Recommendation: If you want a real sweet hand pump that gives no hassle, this is the one for you.

Pros: lightweight, compact, smooth action, great grip.

Cons: None so far

Recommendation: Great pump, easy to use on the trail. Even use it at home.

Pros: Pumps tires to proper pressure quickly, smooth action, good grip, lightweight, and compact.

Cons: A little tough to keep it seated securely on presta valves. If the nozzle was a little deeper it would be perfect!

Recommendation: I honestly can't believe I'm giving a hand pump a 5-star rating. I've never owned a good on-trail pump but the Mammoth is so great I could almost imagine using it at home or at the trailhead as well. Great value and probably the best hand pump I've seen.
