Discovered a couple days ago that the rear brake on my nice road bike was dragging badly. Like, give the wheel a spin and it would stop in half a turn bad. No clue how I never noticed that in the not quite a year I've had the thing.

The insane part is that for a similar effort, my nice bike with a dragging brake still resulted in something like a 2 or 3 mph higher average speed than the still pretty nice gravel bike. I haven't had a chance to ride it since fixing the brake so I'm curious how it does now.

Although, that also would explain some downhill coasting speed weirdness I noticed on group rides.
