Why disc wheels

According to Fulcrum, the Racing 4s have even been adopted by Cofidis for their training bikes. A workhorse wheelset with some thoroughbred traits.

This is despite being broad at 20mm across the inside. Tough enough for gravel, easily fast enough for the road. This broad-rimmed carbon wheelset will support both oversized tyres and rides, thanks to a 25mm inner rim width and no weight limit. The V in the Aeolus Pro 3V name stands for volume. Best set up this way and with tyres 32c wide and up, doing so should give you the optimum profile for both traction and aerodynamics. Backed by a generous crash replacement programme and lifetime warranty, they should keep rolling as long as you want them.

Able to be run either tubeless or with conventional inner tubes, their 19mm inner diameter and Nippier than a shallow wheel but less hairy in blustery conditions than the more common 55mm depth in which the TC wheels are also available , we found ourselves keeping up on the hills and not getting blown about on the flat, so we were happy all round.

Read our full review here. Forget the fact they're aluminium and not carbon. The fact they weigh just 1,g and promise to be super durable means they're still well worth considering.

This is further aided by using DT Competition Race spokes. Available with quick-release endcaps or 12mm bolt-thru front and 12mm x mm rear bolt-thru axle compatibility. Disc wheels are performance boosters: get one and you should go faster. However, having a decent front wheel and aero helmet, good positioning on the bike and clothing that fits properly are even more important, and will save you more time per pound spent.

Seriously, covers are so inexpensive and easy to use that it doesn't make sense not to use one.

Good question! I'll offer this anecdote for your consideration. Edited March 24 by tryandtest omission. Pigdog Buy your wife something nice she sounds like a keeper! The answer over on Slowtwitch is popularly "always". Nob 9, Stubbsy 14, You were clearly dreaming my friend. Will fix links, but another similar interesting swissside. I'm not sure I understand. Is that negative drag at 20 deg from a headwind?

Are we talking true or apparent wind here? I can't see how you could get negative drag without a tailwind. Worth a new question? JamesBradbury - The new question would be "how does an airplane fly? DanielRHicks, that implies the wheel is not symmetrical when viewed from the top. Is that the case? Can't see that working very well, except in a wind tunnel.

JamesBradbury - It doesn't necessarily imply that, just that an airfoil effect can be achieved. Air does mysterious things at times. JamesBradbury yes that's 20 deg from headwind. In wind tunnel, because the wheel is stationary, that's 20 deg of true wind. On the road it'd be apparent wind angle. If this raises a new question, I think it would go to physics just to get a deeper understanding of wind tunnel test results. As DanielRHicks mentioned, they call it sail effect.

Another interesting point, if you think it's not worth it because you're not a pro, the paper also shows that slower riders get bigger time gains! That's only true for two wheels with the same mass, distributed differently.
