Pack Pump

[mtnbiker5]

Was wondering what kind of pumps are the best to carry in a pack for fatbike. Just realized my "old" pack pump aint gonna cut it. Lezyne?
Thanks.

Lezyne mini floor pump, done!

I agree completely. I've changed many flats (before tubeless) on my Ice Cream Truck with the Lezyne Micro floor pump. Works great.

Nice thanks.

I have the Lezyne Alloy pack pump. I like it, but the one annoying thing is that the screw-on chuck sometimes removes the valve core. I'm planning to get one of these: http://www.specialized.com/us/en/ftb/pumps/portable-mountain-pumps/air-tool-big-bore-pump

good to know i wasn't the only one that backed out a valve core.

Specialized Fat Pump.

I've found that pressing the little black button on the chuck relieves the pressure and then you are less likely to remove the core. However, the manual also recommends that you apply loctite to the cores...

I have the Lezyne mini floor pump, but I carry it on the bike and not my pack, not something I would want to land on. I recently picked up the Lezyne Sport HV, nice little pump too.

I have used the mini floor pump to add pressure to my bluto, not easy, but it did the job on the side of the trail

I haven't had an issue with either removing the core

If you go with the Lezyne, make sure you order/buy the HV (High Volume) as opposed to the HP (High Pressure). The former is more suited for filling the fatbike tire, while the latter is more suited for shock pressures.

I too like the Lezyne, and I do adjust my pressure depending on conditions.
I mounted my tire gauge to a braze-on the bike using an old key soldered to a 5mm bolt.

@Kaleidopete You make some cool shit man. This may also be my first time seeing a skewer on the drive side.

Hey, you can put it anywhere you want on a braze-on, I just like having it handy.

Doesn't that little black continuously let air out of the tire and when you release it the pressure is still there?

I use a 5/32 open end wrench to really tighten that little bugger and that seems to work for me since I too have accidentally removed the core.

 

[numbnut]

I believe that it only releases the pressure in the hose.

 

[Mumonkan]

if youre pumping a presta valve it only releases pressure in the hose, if youre on a shrader valve it can bleed air out of the tube continuously

they have a new abs chuck that locks onto a presta valve like your standard pneumatic air mechanic tools also

the HP version of the micro floor drive takes an eternity to pump up my miniscule 3" tires so i wouldnt want anything less than the HV for actual fat tires

relevant to our interests:

lezyne has a fat version of (imo) the best portable pump in the game in prototype stage:
