Superstar do some great ones for £7.99
I broke the lever on one of those and the camming action ain’t great – which seems to undermine the point of a 10mm axle in the first place if you can’t get it reliably tight – and they’re heavy with it.
I was very cynical about the DT Swiss DWS things after stripping the engagement splines on one of the early resin ones, but the ones with the aluminium handles are about a million times better, much tougher and all-metal contact where it counts, though not cheap at 27 quid from CRC. Don’t touch the Fire Eye one, I had one briefly, it’s alloy and it snapped. Nice.
