The small-ish cutout in the wheel being the main concern. I’ve managed for years now, but wondering if there’s better equipment out there I can use for this. Running Vittoria Competition Latex tube with 48mm valve and trying to figure out the best option for
Pumping pre-race with Joe Blow pump. I use one of Genuine Innovations adapter. It’s always been iffy, but since I changed to the newer Joe Blow pump, it’s almost impossible to use: it barely seals if the pump head valve is open, and doesn’t stay inside the pump head at all if the schrader valve is closed. So I need to press it into the tube valve, hold it in the head, block the schrader valve all is one hand while pumping with the other. It’s not much easier if you have someone else pumping either because all of that holding business has to happen in and just outside the wheel so it’s not like another hand is all that helpful. I actually dropped the adapter into the wheel recently and had a hissy fit but luckily was able to get it out somehow.
CO2 Inflator. I have this one and the chuck is a bit too big to fit on that in the space. If I do get a flat in a race, I will use another tube with a shorter valve, but still the space inside the disc is quite small. Might try this BriskMore one.
I’m sure there are a few people here with that exact same wheel; what do you use?
Get a TPU tube with 40mm valve and use a crack pipe. It’ll leave plenty room
I have the same setup, down to the tubes and pump. I attached a Silca Hiro chuck to my Joe Blow pump, and it works great. Though admittedly, on race mornings in transition, I carry a Fumpa now.
I use one of these: Mellbree 2pcs Valve Stem… https://www.amazon.com/...ppx_pop_mob_ap_share
With one of these screwed on: Bike Bits Brass Presta Valve… https://www.amazon.com/...ppx_pop_mob_ap_share
Use a bit of loctite to keep the adapter from unscrewing from the hose. Screwing it on to the valve stem causes almost no leakage and it’s sealed once it’s screwed on. Then you can use whatever schrader pump you like. I use a mini Fumpa. The whole kit along with a tire plug kit (I run tubeless) fits in the behind the seat container on my QR PRSix2.
Ditto above - I have the Silca Hiro chuck for my HED disc, and it is great. It is by far the best chuck on the earth. And also ditto above that on race day, I use a little electric pump with a crack pipe.
Use a dremel and make the opening larger. Seriously.
Silca Hiro chuck, nuff said.

I have a HED Jet3 Plus; though it was always set-up tubeless (I figured it would be better to limp home than be stranded).
The following worked for me when using a slightly short valve (can’t recall exact valve length)
Topeak Pressure Rite Presta
I did this exact same thing. Best decision ever. Made it just a smidge bigger but what a difference that made even with using a Hiro.
I use the Fumpa. It’s awesome

My problem with that Topeak is that it was impossibly difficult to screw on/off the adapter to the presta valve given the small space. I’d need pliers, I think. I returned it for this reason.
I have the exact same wheel and tube set up. I’ve found it very doable to do myself by making an adjustment on the placement of the pump in relation to me. I keep it close and use my dominant hand and shoulder by leaning into it. It isn’t the greatest solution, but it beats buying a $70 chuck head. At some point I might bite the bullet and do it. But for now, I use the crack pipe and do it myself.
Thank you. How do you handle pumping up in case of a flat?
Good question.
I have the CO2 inflator with the separate head. I haven’t tested it or even tried to see if it worked. I have 2 spares and 2 tubes in my Speed Concept draft box.
Thanks. I also carry 2 tubes. One thing that’s annoying is that for disc, I need a tube with a short valve, whereas for the front wheel it would be a long valve unless I also mess with valve extenders. I really wish the disc cutout would accommodate both long valve and a slightly bulkier chuck head.
Not really confident enough to dremel my way around the $1k+ wheel though…
I ordered a few things suggested above, will report to see how it goes. I’m starting to more seriously consider going tubeless for race wheels, but none of the problems go away in this case - I’d still carry spare tubes and would still need to figure out how to pump them if I were to get a flat…
Using a Dremel tool on that non-structural carbon is easy.

It’s just a fairing though. There’s nothing at all structural about the disc part of a Hed Disc as it’s a permanently affixed cover to a spoked wheel. Basically you’re just sanding down a few millimeters around the opening.

Another vote for the Silca Hiro.
