I'm trying to avoid the crack pipe solution.... Anyone have any success with Topeak joeblow or silca pista series?

A floor pump.

Any floor pump on the market is gonna be fine, provided you are using it properly and it will take the right valve type.

Wut.

Any floor pump on the market is fine. Crack/breaking valve stems is user error.

Timjohnson

I've tried 3 different floor pumps that do not work. The carbon cutout for the valve stem is extremely tight. This is an HED H3 tri spoke I'm referring to.

Maybe you just aren't doing it right.

Jandro, when did you become a mod?

Did you try any pumps at a shop? You may want to ask in the Mechanics forum or one of the racing forums like Track and Triathalon where you will more likely find a person that also owns one.

A few weeks ago.

Timjohnson, if it's tight clearances that you're working with, try a Leyzne floor pump. They have a minimalist screw-on presta valve.

I use a silca super pista to inflate mine. Best rebulidable pump out there imo. We're talking about a legacy brand; I have one that's 40 years old handed down to me and still kicking! Either only takes a few actuations to get up to 120+ PSI.

Forget the zipp crack pipe. It sucks! You'll find it always blowing off the valve from the pressure if you don't awkwardly press the chuck down on the valve while inflating.

I personally use a hirame chuck for all my wheels with a locking mechanism that's slim and unintrusive enough to fit aero wheel cut outs, worth every penny.

Timjohnson

You're right. This was probably a better question for people who own and use this wheel

Timjohnson

I've heard of this. This is my last resort as its pretty expensive but seems to have good reviews

Timjohnson

Ideally this is what I would want. I guess I'll ask in the triathlon forum to see if anyone is using a pump w a screw on valve.

Topeak has a thread-on style crack-pipe that may help - https://www.topeak.com/products/Pumps/Pressure-Rite

the crack pipe's not that bad...get over it.

Leukybear 

Actually looked promising until I saw it's meant for schrader and saw reviews of people using it on cars and motorcycles on amazon.

Timjohnson

If it didn't require two people I would be over it. I live in a dark studio by myself and need to be able to pump quickly, without lighting, and by myself. It seems the lezyne and silca are the best options.

Just squeeze a rag in the valve arch, over the crack pipe and voilą.

+1, with one caveat: the screw-on chuck contains a fancy "ABS" mechanism that allows you to bleed the hose pressure before unscrewing it. To get this to work at 100psi or above you'll have to bleed the tire a bit *before* screwing on the chuck. Otherwise you'll be putting a couple hundred pounds of pressure into the hose and none into the tire. Once you get that routine settled in, the Lezyne is a great pump. Same goes for the hand models.

Timjohnson

I tested the lezyne today. It was a pain to scew on because I could not get my finger around the stem. Once the valve head is on there is no room for anything else in the cut out which basically means I either have to hold it in place or have it screwed on by just a few threads before it becomes impossible to thread. Lezyne does offer a slip chuck which is their 90degree adapter for disc wheels. I'm going to experiment with this at rei tomorrow and hopefully be done with this issue.

i used to have hed 3's. and had no problem pumping by myself. i used the silca adapter.


plus my serfas fp-606. it's dual stage or whatever so i can pump with one hand really easily.

I tried the Topeak JoeBlow X.O. over the weekend. It has a screw on fitting that I couldn't get to seal and was a huge pain.

It looks like the two best options are still Silica adaptor + a friend, or a Hirame chuck. It might be $80, but it probably saves $80 worth of hassle over the lifetime of a disc wheel.

Timjohnson

I tried the joe blow pro and it actually fit, but for $100 if felt really flimsy and of cheap quality.

I ended up going with the lezyne. Most of their models now come with a "slip chuck" which is their 90 degree adapter for disc wheels. Unfortunately I had to hold it on the stem while I pumped with one arm. I was able to get up to 105 psi though, which works for me. I wish i would have have went with the silca due to its rebuild factor but I didn't feel like ordering online. Maybe if this thing ever breaks...

I tried to like the Silca Pista floor pump we got at the shop but couldn't get into it. The wooden threads in the handle wallowed out and the piston lost most of its seal about as quick as any other floor pump in heavy shop use. When a typical floor pump is no longer able to get good compression I have found that the culprit leaking rubber o-rings on the piston head can be salvaged by removing them, stretching them a good bit by pulling on them with your fingers, and then reinstalling them with some Finish Line Wet lube, or similarly viscous lube. Hopefully this trick will save someone money and frustration.

Did you replace the leather gasket on the silca? (~$5 retail, most likely less w/ LBS discount)... Handle can always be rigged.
