I would have to vote for an Echo rim in this situation. They may be heavy but they make up for it in the strength As for a hub, if you are wanting to run a freehub then a Hope Pro II is the best value for money option but if you are willing to spend a little more on a hub they you can't go wrong with a Chris King On the other hand though, if you are wanting to run a front freewheel then a monty, koxx, viz or trial tech hub will do the job perfectly. With a rear fixed hub you will want a good front freewheel, I would reckommend an eno if you can afford it but if not then a tensile will do a very good job Aden :)
