Your better bike shops should be able to order a wheel for your bike

I have rebuilt using the existing rim and different spokes , myself. thats OK too
then the rims match. (obviously )

Shimano Alfine Dynohubs have the Disc brake fittings as do the pricier German Schmidt .

The LED lights are many as well .. NB Peter White is a Importing Distributor for the German Schmidt,
In US & Canada ( yea he has an Attitude .. keep it to just saying what you want
item and part number , and be succinct)

They will open an account with your local shop then you pay retail
(dealer margin is including shipping ),

you can buy direct from Peter , then He adds shipping onto retail prices.

Others skip US sources entirely and use European sellers .. then again shipping is additional to cost of parts.

[ I have a older 6 bolt Schmidt & a newer Centerlock disc mount.. Black anodized shells . ]
