what rear track wheel?

Tis true......

That said 36 hole tied and soldered can be a little OTT if your not a sprinter...

Hard to get 32h DA track hubs.

But it doesn't really matter. The GB team use DA 36h hubs and open pro rims (tied and soldered) as training wheels. And so do I, mine have lasted two years without need of attention. I do have to service the bearings this winter though.
