Upgrades

Hi guys
I was just looking for some help/info. I'm looking to upgrade some of the parts on my bike, it's a cube attention. I was just wondering where to start or what would be best to upgrade.
Cheers
Robbie
Ride the sh!te outa it til something breaks, then thats the bit you replace 1st. Simples.
Save your money and buy a new bike when you can afford it, however tubeless wheels/strips would be a good investment.
Tubeless the best suggestion a man can give and buying from Expert Cycles the second best suggestion for Tubeless ;-)
