Hi folks,
during a ride today I lost the adaptor I use to pump my Hed3. I do have that silica pipe thing, but it’s not what I prefer/am talking about. I use the following:
So this is an older style hand pump with a flexible tip that’s woven cloth. the tip connects to the pump chamber on one end, and presta/schrader valve on the other. I like it because it screws on the valve, so hands-free, and if using CO2 catridge, the other end of tip screws into the CO2 adaptor, so no lost air.
I have a sense of urgency because I am doing IMMoo, and I think I need this adaptor if I get a flat on course. Pre-race I can manage with the silica pipe.
on ebay, there are two auctions, but they are both based in the UK, and it won’t get here before the race. this reminds me that I must have purchased my pump when I was living in england.
questions:
does any one know where I can get this in the US, so I can get it by next Thursday?
what is your recommendation for CO2 pumping up after a mid-race flat on a HED3? My CO2 adaptor doesn’t fit well on a 48mm presta valve; 60mm valve may work if I bend it out excessively. I always lose a lot of air using the silica pipe.
from original poster:
beside my sense of urgency in preparation for the race, I think this is a good method for those asking questions about how to pump up a hed3 or discs; apparently all the vendors for this product are UK-based…
again, please let me know if anyone knows where I can get this item:

thank you in advance for your help!

I have an Ultraflate Plus. BTW I have a Hed3 and use short stem conti comps with no filling problems.
from original poster,
yeah, thanks for your replies; I have a xlab saddlewing with xnut and was hoping to stick with the small CO2 adaptor with threaded co2 cartridge; BUT… i think i’ll find an ultraflate system, which seems to be easiest for hed 3 during a race;
simple question:
now that I am getting rid of my xlab saddlewing/xnut/xstrap, how do you guys pack the stuff below/behind the saddle? I had used a small bag that hangs from saddle rails and post, but won’t use it during race. I also don’t want to fit ultraflate and accessories in my clothing.
things= 2 tubes, 2 CO2, two tire lever, ultraflate
should I bundle things together with rubber bands and then somehow tape things to the saddle rail? duct tape or clear packing tape? Anyone with experience of not losing things
or should I just using saddle wing and xstrap things in?

If you wanna stick with this setup, why not get the innovations Microflate (http://www.trisports.com/inmickit.html). I haven’t personally tried it with the Hed 3, but they claim it works with disc wheels so I’m guessing it will work.

If you’re getting rid of the xlab, I don’t see why you don’t get a small bag. I can fit 2 tubes/2 co2 cartridges, 1 lever and my ultraflate in my small trek saddle bag.
from original poster, now on IE, instead of netscape; (wow, look at all the functionalities…)
thanks for suggesting microflate; have you and other people had problem with not being able to control the rate of CO2 flow? I am paranoid and think if I put in air slowly, inner tube is less likely to get torn, if it is twisted somewhere or caught under the clincher bead; I use an adaptor that regulate flow rate:
because of this configuration, it does not fit into the valve space for hed3; I imagine ultraflate and microflate would work fine for hed3
from original poster, thanks for the information;
yeah, I bought a ultraflate today; neither LBS I went to had microflate;
my original adaptor-- picture above – a knob to control flow, so it’s in shape of a T, can’t fit into Hed3 slot; $5.99
ultraflate – a trigger to control fow, it’s it’s only a right angle, and can easier to get into HED3 slot; $16.99
I still like the item I was talking about at the beginning of this post:
this essentially serves the exact same function as the silica pipe, except it’s hands free because it screws into the presta valve; the other end can be connected to CO2 adaptor or floor pump; the UK vendor I found has this for 1 pound; so I think I’ll buy a bunch and ebay auction this thing; the silica pipe cost $8-10 range…
If anyone is interested you can go to below link and order one for yourself;
It sounds like you might have already solved your problem, in which case you can disregard this message. I have a Hed 3 trispoke and I use a Microflate with a 16 g threaded CO2. The flow can be turned on and off by rotating the bottle and with a controlled rotation I first only allow a little CO2 in and then spin the tire and check for a pinch of the tube. Sounds like it takes a while, but it’s not that long and changing the tube again would take a lot longer. I also use th 16g so that I have a little extra CO2. I think another poster posted the difference in cartridges, but 12g is like 100psi and 16g is like 125g if my memory is correct. (I usually fill to about 115psi when I have a gauge). I also just use a regular stemed tube nothing fancy.
As far as where do I carry the stuff during a race. I wrap 1 tube, 1 16g CO2 cartridge, 1 microflate adapter, and 2 plastic tire irons with a rubber band. Then I put them in a regular old Sandwich type plastic bag. I have a behind the seat 2 bottle holder, you know the ones that hang down a little, well the bag fits snugly up under my seat, with the CO2 almost fitting between the rails, and I wrap black electrical tape around my seat, plastic bag, and bottle holder. The tape sticks to the plastic bag pretty well and I just make sure that I can easily remove the tape. (ie I make sure the last piece of tape is taped over a previously stuck piece of tape) It does a pretty good job of keeping the tube etc out of the airflow, as if the bottles don’t muck it up enough, but it does the trick.
