American Classic's super light magnesium wheel set

Axus Cursa wheelsets will set you back €460 and the claimed weight is less than 1300g...

The mag wheel has a pretty light hub too

Magnesium isn't an easy material to make a rim from but AC say it's worth the effort: it's only 300g

The AC hub pawls engage via a timing ring rather than a spring, which makes for a surer engagement

The AC420 has been redesigned, with spokes redistributed on the rear wheel

AC have redesigned their Alu nipples so that the thread is under compression, which they say stops fatigue breaks.

The AC 420 has the same rim as before

A-Xus wheels from Germany use a mix-and-match approach to get light, good value wheelsets

The hardened steel inserts stop your cassette eating up the freehub body
