I bought one of these.

Maximum clearance is 30c, 32c is dependant on wheel and tyre combination.

I paid $1800 delivered to Australia.

If I had my time again I would have just built up a bike from scratch. If you start replacing parts it will end up costing a lot more.

The wheels are really heavy, 1900 grams. (I got the carbon wheels)

I have replaced the following: Crankset, axles, saddle, tyres. New wheels will be the next purchase which will take the bike to around 7kg.

Hi I'm in Australia also, and it seems like an awesome deal still. I would want to get the weight low, are you sure you were able to get it to 7kgs? That seems perfect. I have rim brake light bikes at 7.2, so if accurate that would be very cool. I would also want to change to 38cm bars.
