Depends how you define “road bike”! It seems to mean road racing bike these days, which I think is a bit of a narrow definition.
Most of my riding is on a Kinesis Pro 6 frame, fitted with disc brakes, rack, guards and dynamo. That gets me to work, tows a trailer occasionally, handles winter training, has done some long distance Audax events, and does a bit of touring. I’m not road racing these days, so my racing bike doesn’t get used much at all.
I would pick the bike that best suits the riding you do most. For commuting, rack and guards would be a must for me, and I’ve been using discs on what I would describe as a road bike for 13 years now.
