Are all 9mm front through axles QR? I’ve always liked allen-bolt QRs, and would prefer a 9mm version of one if possible, but haven’t found any yet

I have some on my commuter. On-one IIRC.

loads of people do bolt up ones

Do it properly:

ah sweet, that answers that question. Booyah!

OK, next question – why doesn’t Google show any/ I can’t find any online – any pointers?

Hmm – carlosg – they are 5mm – your not looking hard enough are you!

Either as Cynical says either a bolt up, SSC QR (which I have got and are fine) of the DTSwizzle RWS QR 🙂

Ah, so the actual answer is ‘the branded 9mm axles are QR; if you want bolt up, make your own’

You can but I wouldn’t make one – the boltups you can easily get from shops and CRC, ukbikestore etc etc.
