Avid Ultimates are great brakes too and very adjustable. I just did a gravel road race yesterday with some pretty muddy sections and never wished I had more braking.
Really? Wow, what a very strange coincidence!
I have a complete set of NIB Avid Single Digit Ultimates (1D-ULT) that my brother gave me as a birthday present many years ago. That build then never happened, and so there they have sat, in their nice Avid boxes. I pulled them out of storage earlier tonight and was looking at them, and then I saw your post. Interesting.
I need to call Campagnolo today to see if these will work with Chorus Flat-Bar levers on this new build (new to me Moots Psychlo-X with ENVE CX fork (why I need cantis, etc.) for daily all-weather commuting + good/bad road riding that I want to explore). I know that Chorus F-B levers will work with short-reach or long-reach road calipers, and with cantilevers, but I don't know if they will work with Mini-Vs, etc.
I've been looking at Mini-Vs, because I have read so many complaints regarding cantis (and I don't need the "better" mud clearance, etc. that I gather cantis provide), but the entire cx brake topic is still confusing to me.
I do not even really understand if the Avid Ultimates are "V' or "Mini-V"; if "linear-pull" (Avid Ultimate) and "direct-pull" (Paul MiniMoto) are the same thing, or different; and if "long-pull" (Avid Ultimate) and "short-pull" (Paul MiniMoto) are again the same thing, or different. I have used only one brake almost my entire life: various Campa calipers on road bikes, so my experience is definitely zero re: cantis, etc.
If the Single Digit Ultimates I have are indeed compatible with Chorus F-B, that would be excellent. They are 10 years old, though, and discontinued as far as I can tell; I wonder if current brake pads (i.e. KoolStop) will fit them. The pads that are with these are, I assume, Avid, black, marked "DIN A".
I remember you from years ago when I used to participate here and on some other fora with much more frequency. You always wrote excellent comments (and posted some very nice builds iirc); so it's nice to see that you're still active here.
Cheers, and thanks.
