upgrading bike parts can be expensive- what don´t you like about your bike at the moment?
if it was me I would just fit some slick tyres and bar ends and just replace other components with better ones as they wear out. Unless something isnt working right?
I think that much of this high end/low end stuff with bikes is just manufacturers hype. As long as the low end stuff is doing its job then there is no point in upgrading.
