Digging around in the spares box, I found a 20mm to QR adapter for a hope front hub but cant remember if the XCs or bulb could be converted from 20mm to QR – one can and one cant !!
I know a pic would be useful but cant seem to post one, its fitted by removing the circlips and ends then inserting the adapter THROUGH the hub so it runs on the bearings and is nipped up by a 5mm allen key in each end ….

Bit vague I know but over to the gurus …

XC couldn’t run 20mm.

I’m sure the bulb can be converted, no idea about the xc though.

I have both – Bulb yes to 20mm XC no can do

Cheers folks – must be for the bulb then … 🙂

If the adaptors are the same size, tgeyre for 5 bolt hubs, if they’re different sizes, they’re for the 6 bolt version.
