Last winter I had an accident because my brakes failed. The irony is that I am very serious about safe driving; I definitely spent a few hours of my life reading about what rules to follow when driving at this time, something like this http://bestadviser.net/how-to/how-to-keep-riding-in-wet-and-cold-conditions/ and I have a lot of practice by the way. So I strongly recommend you dont repeat my mistake and pay maximum attention on your brakes.
Hey, I have seen your Video. Thanks very much. I have a 2012 Felt F75 and after 7 years the brakes become really worse. So I´m really interested in an Upgrade. But in the Link to the Standard mount there is written, that I need 105 5800 shifters, which would cost me 160 €. Do I really need them?
