    Aeroheat/Dyad with schraeder?

    Has anybody used Aeroheat rims with schraeder tubes? Failing that, can presta tubes be used in a pinch in rims drilled for schaeder tubes? What I`m trying to avoid is the need to carry two different styles of spare tubes when I go out with my wife or the kids. As of now, everything at my house from wheelbarrows to motor vehicles uses schraeder style valves, and I`d kind of like to keep it that way for simplicity`s sake, but I`m seriously considering 26" Aeroheats for a new wheelset.

    You can:

    A) drill out the presta valve sized holes for Schraeder
    B) use an adapter to put a presta valve in a Schraeder valve hole
    C) carry a spare presta valve tube (Simplest solution)
    Bikes use brakes to stop.

    If your bike has breaks, don't ride it.

    A) drill out the hole- my concern here is whether the valve stem will reach through the fairly deep rim.
    B) adapter- ah-ha! I didn`t know about that. Can they be installed and removed easily on the roadside? If so and if A) doesn`t work, that sounds good.
    C) Carry both types of tubes- Yeah, but...

    Thank you- I`m off to Google up adapters.

    EDIT: Google sent me back here- an old post mentioned just using a rubber grommet. Sheesh! Why didn`t I think of that?

    I've got Dyads on my tandem. It looks to me like a standard length presta valve leaves a comfortable amount of length outside of the rim to attach a pump. I even took the time to compare a schrader valve stem to a presta (they're about the same).

    That's a pretty stout rim extrusion so I doubt the slightly bigger hole will be an issue. I'm thinking it's a pretty major convenience to have all of your tire valve stems match. If it was my bike I'd probably do it.

    ehhh... why don't you just get seatbags for the other bikes, and use the opportunity to teach them how to change their own flats?

    That's Rule No. 1 for family cycling: Everybody fixes their own flats. I often wind up doing it because it takes me a lot less time (years of practice makes semi-perfect), but everybody knows how. Every rider also carries basic tools and a pump, though when we all go together, we might leave a pump or two behind.
    I don't know those specfic rims, but I'd be leery of drilling the holes out unless they're pretty stout. Any bike shop can sell you a presta-to-Schraeder adapter for a buck or so, and you can store it screwed right onto the valve, like a cap. All my tubes and pumps are presta (13 bikes in the family), but I carry an adapter anyway, just in case everything breaks at once and the only air source we have is a gas station hose. And there are lots of pumps out there that will handle both types, either with or without a minor adjustment.
    Schraeder valves really aren't ideal for bikes because you have to overcome the spring pressure when you're inflating. With a standard frame-fit or mini pump, that can be significant...to be honest, I never have thought of valve compatibility as a problem. You can't carry the pump you use for the boat trailer or ATV or whatever on the bike anyway, and I never ride without a pump, so I just carry one that works.

    Balogna! I've inflated schrader and presta valve bike tires using a variety of pumps for decades. I see zero difference in inflation effort using a hand pump. Using an air compressor, the schrader wins hands down being both faster and easier.

    Thanks for the answers, everybody- I decided I`m going to order the Aeroheats. I`ll measure the depth when they come in and if it`s enough for schraders to poke through I`ll just ream them out. If not, I know there`s still a way to get by with the same tubes as spares.

    At least one of my mini pumps and my floor pump work for both types, maybe all my pumps, so that isn`t an issue. With all the metal on these rims, I`m not worried about weakening it by any measurable amount just from opening the existing hole a little bit more. Teaching everyone to repair their own flats is a dandy idea that I really should have been doing- maybe I`ll get on that one more, but I`m the only regular biker in the family and the rest rarely flat, meaning few chances to teach/practice. Carrying tools, pump and tube on all the bikes is probably not a bad idea either, but I really don`t want to shell out when in all likelyhood the stuff will only get used when I`m there on one of my own bikes anyway and already carry it on all of them. Thanks again guys- I appreciate the answers.

    EDIT: No problem with pressure either- the highest I use is 50 PSI in a pair of 26 x 1.5s No 23m racer-boy stuff at our house.

    Not an issue anyway. Check out the valve on your home's air conditioner. It's a schrader and it operates at 200psi and is expected not to lose any pressure.
