If you want to sell those tyres let me know! Been looking for a pair of those for ages!!
I found that a cheap way to save some weight is to change the chainrings.. Doesn't have to be the whole crankset.
Tyres and wheels are definitely the first thing, but don't change too much in the first month or two until you really know what you want to change!
Any Cube dealer should have those tyres in stock. We have here in Denmark..
Back to the bike:Future upgrades would be a lighter,more adjustable fork,and lighter inner tubes. Geax gato tyres mentioned above are great,and cheaper than shwalbe. But go out,get it dirty to begin with
