Very interesting. What do others say about the longevity of 10 speed (or for that matter, 11 or 12 speed) systems? (This is perhaps moot, because your system calls for friction shifting, but I've heard quite a few say that 10 is actually more durable than 9. Is that true?
Regarding the flat plate fd: also very interesting. I installed an admittedly weird 26/40/44 triple on my Matthews (Long story, but involves OCD, a lot of both road and dirt riding and a theory about a High range for road and Low-[er] range for dirt roads; and components at hand -- and this may be changed eventually to a 42/26 double) and for other reasons (OCD again, and the "*road bike* for dirt" conceit) I used Dura Ace 7410 f and rear derailleurs and a home brew 15-30 9 sp cassette. The second of the 2 DA fds has enough throw for the Bontrager mtb crank (after I cut off the limit tab) and shifts quite well while avoiding hitting the chain stay. (If I go to a double, I'll have to revert to the earlier DA fd with shorter throw). Finally, Silvers: I disagree. They don't slip if you locktite the bolts, and because they no longer need adjusting mid ride, I dumped the little ring bolts and installed M4 button head bolts held in place with blue loctite. No loosening over the long term, with both Fargo and Matthews. In fact, I've found that the Suntours Power Ratchts slipped as readily as the Silvers, loctite apart, and old Campy R are impossible -- they have for a long time been notorious for slipping; again, loctite fixes the problem. And, I never had Retrofrictions slip at all. The old Dura Ace slipped and in any event have very limited throw; the later 7 speed indexed Suntour ones, run in friction, don't slip and can handle 8+ if you judiciously file the pod. The possible problem with the Silvers is the little plastic washer which tends to crack. Also, the Silver pods will rather easily crack if the bike falls over and lands on one.
