Yeah, came to those conclusions anyway. Settled on this frameset:
Wayward Bicycle Company
reviewed as a decent, Australian alternative to an LHT, good chance to support a local
Picked up a heavily discounted 28/32 spoke 700c wheelset by wheelcraft
Click Bike bicycle clearance boutique (Salsa Cycles & All-City Cycles)
I only planning on carrying about 10-15kg on the rear and max 5kg in a handlebar bag on the front. I like to travel light and will never be far from a town on my planned route.
Most other components from the Cadex are still in good nick and will work well with the set up.
Thanks for the replies!
