Not sure if this is old news but apparently Chris Kelly is coming back. I doubt now is the best time to stage a comeback to the frame selling biz but it’s good news if you always wanted a knobby-x or “take-offs”.
Those look better than what I was referring to (whatever it is that’s listed on the Kelly site). Still, seems like the suntour ones might get in the way when sprinting or climbing out of the saddle with your hands on the hoods, though maybe I’m wrong. They seem to be worth a try, though.
