Fenders - Size up or Down
Hello I recently picked up a Kona Dew and have been having some struggles trying to fit fenders. The tire size is 650 B by 47 mm. Currently I have a pair of fenders 700 C by 50 mm which seem to fit reasonably. I know the rule of thumb is to have fenders 8 to 10 mm wider than the tire. The problem is the fork on the Kona is pretty narrow at the top which would squish fenders of that width. The 50 mm fenders currently in there, although do not provide more than 3 mm of clearance over the tires, fit nicely between the fork.
so my question is would you prefer to have fenders that are perhaps not the ideal width for tire coverage and fit nicely between the stays and the fork? Or would the preference be to have wider fenders that might need some modification at the fork but cover the tire?
Thanks
