Andy Reed used three question marks:
1. regarding the fact that the 27F is hard to find: "Any insights on this?" Nope. I always bought mine from Alex's Cycle in Japan and even they don't have it
2. regarding the manufacturability: "Is it just an incredibly time-consuming rack, they only make a very small batch of them at a time?" I'm sure it is time consuming, and I expect it's just low priority relative to other hot sellers.
3. Regarding the status of the 27F: "is the Campee 27F still the GROAT and worth the wait? I think it is indeed the superior front rack. Whether it's worth the wait depends on the person doing the waiting. I think that the best way to run the 27F is with rectangular panniers that are designed to fit that same size and shape. If you've already got "normal" looking panniers from Ortlieb or similar, I think that's a weird looking setup. I personally have one pair of Ostrich and one pair of Carradice panniers to run on my small collection of these Nitto front and rear racks. I've got 2 of the 27F fronts, one of the more burly "Mt Campee" front I think they call that the 20F. I've also got two of the 700c rears, the 27R (or is it R27?).
The only way to do it better IMO is a custom that copies the setup but in lighter tubing or a more minimalist set of contact points designed around the bike. Those top notch rack makers are in a class by themselves. Off the shelf, the Nitto 27F is the business IMHO.
