What is the lightest QR15 hub with six bolt disc mounting?
Is there ever going to be a QR15 hub without six bolt mounting? .... well... maybe centerlock.
Do QR15 hubs even exist yet? I emailed WTB if they were ever going to have a QR15 adapters for current Laserdisc Lite hubs, and they told me they weren't... but they were just going to have a QR15 version of the Laserdisc Lite. The current one could not be adapted. The current regular QR Laserdisc Lite hub is already pretty silly light at around 150-ish grams.
It was a few months ago, but I think they said something about January when they would be for realz.
Then there is Hope. Hope stuff is not usually super light, but its really good stuff.
