 Yes you must know more than the engineers that design parts for an Olympic sport. Lotus designed the bikes for the UK team in China this year. Solid axles. You should reach out and tell them that hollow axles are better.

 Lightweight carbon hub, then uses chunky solid axles with steel flanged nuts on the end...

 It's a track hub. The power these guys put down requires strong parts and high torque.

 @z-man: yer but solid axles like this have a worse weight to strength ratio and a large diameter hollow axle like most good bikes use.

 @maglor: You don't understand track racing. Worse ratio, but still stronger. The bolt force needed to keep a wheel in place, with a 90 inch gear at 2000+ watts at a low crank cadence is insane. A Hollow axle just wouldn't cut it.

 @maglor: As you can see on this NJS site listing high-end track hubs, almost all of them have solid axles. The ones that aren't hollow are just for the front wheel.

 @z-man: No i don't understand track racing but "a hollow axle just wouldn't cut it" is very short sighted, just becuase everyone does it doesn't make it the best solution, mountain bikes used to always be quick release...
Maybe one of the current hollow axle standards might not be designed for forces of track cycling but if they were actually "high end" and tried to create something better you could achieve a better strength to weight ratio with hollow axles which means you could beef up a hollow axle to aceive the same strength and have less weight, and back to my original point it seems daft to go as far as carbon hub bodies but not look at the possibility of a lighter axle setup. Choosing a solid axle becuase a strong version already exists seems lazy from the track cycling world, but it easy to be a critic from the outside.

 @z-man: All this talk of strong axles but i actually reckon the main reason for using solid axles in not strength of the axle but more the strength of the cup and cone bearing system that comes with it, they have more space for larger bearings and the adjustment allows you to tune out any friction and track cycling will benefit hugely from low friction, plus sealing and servicing benefits of cartridge bearings is less of an issue when not outdoors in all elements, also Shimano has always been a big supporter of cup and cone bearings and must admit thier pedals are bullet proof becuase of it.
