Crank Brothers Alloy Power Pump w/ Gauge

small and light is nice, but it actually works too! use it in the woods and even on the road. has a dual pressure feature that you need for high pressure. i throw it in my bag, but the frame mount velcro feature is pretty sweet if you go that route.

Pretty small, great high volume/high pressure feature. Built solid.

I already had one of these on my other bike, so when I got my new bike - I got this one. I like the weight, and the fact that it has a pressure gauge as part of it.

The only issue I have with it is that you have to thread the strap through a thin slit to reattach the pump after using it, and that can be a little tricky when you're pumped.

I just don't know... not very happy with the pump to begin with... and over time it just got worse. I have had the pump for several years now... so this is a long term review. Parts sort of started falling off it here and there, but I was able to rebuild with parts from other pumps. It is a pain to work the pump, flipping the head around, turning the pressure switch on the bottom...anyhow there are a lot of pumps out there... I would suggest looking somewhere else... in fact... I am on the site now to find a new pump as this one finally died... does not work any more.

This pump is certainly from a well regarded manufacturer and looks cool, but it doesn't actually pump up tires very well. The high pressure mode doesn't move enough air, and the high volume mode requires everything you can muster. Broke mine because of the force and effort needed to pump up a tire.

It works well for a hand held pump but it does take a little while to pump your tires up. I mainly have it for a trail pump but if I'm doing something at home I'll just use my roommates floor pump.

I imagine it works great for tires other than road bikes. I couldn't get enough pressure to ride on. I'm keeping the pump in case I need it for when I get a mountain bike but absolutely not recommended for road bike.

Nice to have both presta and schrader without having to re-rig. It also seems a little more well-built than some of the other compact pumps out there. It is small, so takes some time to get to pressure, but good overall pump. I'd buy again if I lost it.

So i may have an unrealistic expectation of what pumps of this nature should do but i think this pump does the job but it's not amazing. It takes a lot of pumping to do the job. Also it only pumps on the inward stroke.

Yes, the volume is small. I have presta, my wife has schrader. Rather than switch the innards, it's easy to use either one. Lightweight and built fairly well, I'd hate to have to pump a road tire with it, but I don't have to.

Don't quite agree with Nelbow. I found this pump do deliver quire well. I like the ease with which it switches from low to high volume and vice versa. Only thing I could see improvement on would be the mounting hardware. I replaced the zip ties with some generic hook and loop strips (velcro). I found it very easy to get my 700 series tires up to volume otherwise. Maybe Nelbow should hit the weights a little.

The pump works well enough, but the attachment to the bike uses a strap that you have to thread through a small slot when you put the pump back on your bike. It is a bit finicky wearing gloves when your heart is pumping, you've just lost two minutes changing a tube, and you want to get back in the race.

This is a solid pump that certainly takes care of business...although not as quickly as I was hoping for. The alloy construction is bombproof and the dial is key. If you want a semi-small, fairly-light tough pump to throw in your pack just in case, this is the one.

*As a follow up to the above review I recently broke this pump while on the trail. I placed the pump over the Presta valve of my recently replaced tube and the entire head fixture broke. It is now useless. I have only used this pump a handful of times and I must say that I expected it to last longer with very minimal abuse. I am changing my rating of this pump from 4 out of 5 stars to 2 out of 5 stars due to construction.

With the whole double-chamber thing, I expected this pump to do a bit better, but it's still pretty good. This thing is super tough, and it's really nice to have a gauge on there. The gauge isn't super accurate, but what do you expect on a tiny hand pump?

Fits great in my small pack, this unit is going to last me for a long time. Not a lot to break on this pump, everything seems to be made with quality in mind. Pretty nice to get a pump that will actually work every time. I can go into my rides deep into the backcountry with confidence knowing that I for sure will have a working pump if I get a flat.
