Need a set of road wheels, but don't want to spend much over the £120-130 mark. I've not much clue when it comes to road gear, I've seen Shimano RS30 and R500 wheelsets but can't really tell much difference between them to justify the price difference. Also noticed the Planet X AL30s.
Which of those three are the best? And is there anything else I should be looking at?
All advice appreciated.
