Honest opinion piece on disc brakes
Just read The Russian Crank opinion piece about Chris Froome's comment on disc brakes and how they are becoming mandatory. Below is quoted from the piece and really does sum things up with complete accuracy.
"They started their life like any other new product on the market. People who liked them, bought bikes with disc brakes. Everyone else ignored the fad.It would have stayed that way if not for this caveat — you can’t buy just a pair of disc brakes and install them on your bike. If you want them, you need a new a bike. And who wants to sell more bikes?
This is where the sponsorship angle came in. Make the pros use disc brakes, spin some marketing ******** about stopping power and rain and boom, sell more bike."
