I have read from many different sources, as well as talked with many bike shop owners about why canti-lever brakes are supposed to be superior to linear-pull V-brakes in adverse conditions, i.e. like muddy rims. Cantilevers are "supposed" to provide superior stopping power for Cyclocross racers in these bad conditions. If this is the case, then why don't Canti's come on todays Mountain Bikes instead of the more prevalant linear- pull V-brakes? Mountain Bike riders/racers are just as likely to encouter these adverse braking conditions as Cyclocrossers! Anyone have any ideas?
