I'm wondering if pedal washers are necessary, or even recommended, when riding with a carbon crank, in order to avoid damage to one's crank arms?
The main reason I ask is because I prefer to ride with the smallest possible Q-Factor, and having any type of washer in place increases this insofar as ones feet will be positioned farther apart.
The Q Factor of a bicycle is the distance between the pedal attachment points on the crank arms, when measured parallel to the bottom bracket axle. It may also be referred to as the "tread" of the crankset. The term was coined by Grant Petersen during his time at Bridgestone Bicycles.
Can I safely ride my carbon crank, sans pedal washers, without worrying about long term damage to the crank arms?
