Rim Brakes on Carbon Wheels
Thinking of buying a road bike with rim brakes and carbon wheels? Do you already have a road bike with rim brakes and you want to switch from alloy to carbon wheels? Stop and consider the following:
Bikes are lousy at stopping quickly at speed or steep descent no matter what the situation is. But you have rim brakes on your current bike and you want to go from alloy to carbon wheels you may regret the choice when you try to make descents that require slow speeds down steep descents. The difference as I found about between carbon and alloy after switching is greater than I had participated. (The heavier you are the greater difference with carbon than alloy.)
The bottom line the carbon wheels are much less effective than alloy for breaking the situations I describe
Many carbon wheels come with a braking track on the wheels for a better grip by the brake pads. Those wear out in a month or so.
Anyway, a factor to consider if you are considering going from alloy to carbon for whatever reason.
