While you’ve got the wheel off the bike would you be a luv and measure the disc mounting face to disc mounting face distance and also the dimensions of the bit the speedo drive goes into: Height from the disc mounting face Inside diameter and depth if different from the bearing housing bore If you could that would be all of the awesome
Depends how they do it. If they’ve got a wheel mandrel set up so that it ‘irons’ the wheel back to true then it also rolls the whole hoop carcass at the same time. it wont have the equilibrium it had prior to repair, so your wheel weights to true the wheel will shift, however you might find that it might actually make the balance of your wheel truer than when it left the factory!
