I have a 10 year old Trek 7300 FX hybrid which came with Matrix 750 double walled rims. "559 x 19" is marked on the sticker of these rims. The tyres fitted are 700 x 38C (622) - I'm assuming (should I be?) that the rim/tyre combination give me a 700c wheel?
The problem I have is that the freehub on the rear has gone (there's a crack on the inner cone section covering the bearings) and so it's not freewheeling without locking the chain up, and I'm thinking about a new hub and spokes versus a set of new wheels. Looking at the hassle versus cost savings, it seems that Amazon will provide a decent set of wheels spoked, hubbed and tyred for around £60 whereas a wheel rebuild might save me about £10 to £20 on that amount.
