Hi there, hope someone can help. I'm looking at getting some new wheels, "Mavic Cosmic Carbone SLS WTS Clincher Wheelset 2014". There are a few things I want to check before I possibly get them. I read somewhere that deep rims use different break pads, (which I find hard to believe). Also read certain tyres are recommended, is that just sales pitch, I like and trust my continental 4000s. I guess I will also need a new gearing casset too? or will that come with the wheels? As you can see I don't know much lol Thanks
