View Full Version : high performance 24" wheels

I don't actually have a recumbant, I have a fixed gear airnimal chameleon in 24" wheels (click here for details and pics) (http://www.foldsoc.co.uk/Mike/fixed_airnimal.html). I am after some faster 24" rims for it and thought that recumbent riders were the people to ask.

I have seen some nice 24" rims from velocity and as my bike is fixed gear, I could use a lighter disc specific rim without a braking surface at the back (like the aeroheat rims used on the thracian disc wheelset (http://www.velocitywheels.com/default.asp?contentID=535) - they don't have a weight for the rims on their site, but if you compare the hubs and the wheel weights, the disc rim seems to be 150g lighter). I have also seen some funky wheels from HED, but they don't seem all that great when I read reviews about them. I would be interestd in some Zipp or other aero-type wheels, but I don't think they come in 24". Spinergy make some wheel chair rims in 24" size, but I am not sure how compatible they would be.

My main concern is acceleration as I only ride in the city but, often I spend longs periods crusing through traffic at over 20mph so I think aerodynamics could also be important. There are often terrible gusts of wind on the routes I take, so I would not be up for a carbon disk wheel, but a 3 or 4 spoke might be ok.

Disc rims are often drilled offset to be dished.

The only semi-aero rim I'm aware of for 520 is the Velocity Aerohead. I don't know of any fancy carbon wheels for that size.

I can't recommend wheels, but I've gotta say that your bike is by far the coolest folder I've laid eyes on.

Agreed, sweet folder!

That is a really nice folder. As a recumbent homebuilder I could see that as the basis for a cool recumbent folder with just the addion of a boom and a bent seat.

Cheers, I have seen some recumbent chameleons, they make a very neat conversion as the boom can follow the line of the main cross tube. Also the 24" wheels mean you are not as high as on a normal bike, you could even remove the hinged seat post and get an almost conventional recumbent riding position. To keep if foldable, you would have to make the boom attachment foldable though which might be a challenge.

However, there are rumors that Airnimal are researching recumbents, so it might be easier to wait a few while.

I have updated the article on my bike and put it here http://www.minty-ai.net/bike so I can carry on updating it.
