Pair of wheels i’ve had for years & i’m trying to figure out if i can convert them from 20 to 15mm front & 9mm to 12mm rear.
i’ve looked on the website but cant figure out which model they are.

Bulbs, you can’t convert the rear (well not that know of) some people have converted the fronts by using pro2 inserts but you need to alter the one side.

Look a bit like BULBs, if they are the answer is no. 9mm only at the rear, 9 or 20mm at the front. More pics would help.
[EDIT]
Too slow

Bulb front, Bulb or XC rear

I don’t think a front bulb can be converted to 15mm, a rear bulb can be converted to 12mm if you can get hold of the conversion kit.
XC hubs are QR only

Cheers guys

Try removing the drive side spacer & measuring the width of the axle as it comes through the bearing.
15mm Bulb
12mm XC

Yup, BULB can be converted to 12mm with a kit that comprises of rear axle, bearing and end cap. Requires a big mallet. Kit probably hard to get hold of but Hope are great and can probably advise.

A 15mm conversion should be possible but would need designing and turning!

Big uns little brother. I’ve got a set built into 721’s still going strong

Last time I checked (last year) hope didn’t have any rear axle kits.
