Will this proposed transmission work? I'd like your opinion
I am collecting pieces for my Woodrup (Reynolds 531c) built by Mr. Kevin Sayles as a sports-tourer, 73 degree angles.
Hub and Wheelset:
New Ultegra (130 mm/freehub)
NOS Tricolor 600/Utegra, 170, 52/39 (currently has 42 inner) 130 BCD (I hope that a 39T will be easy to find — like over the counter).
New (current production) Shimano FS-400 DT (braze-on) — INDEXED ONLY, no friction option
Vintage Dura Ace — (can't get the number right now)
* OPTION (A): RD-M650 Deore DX; long cage
** OPTION (B): RD-6208 600EX (SIS)
8 speed CS-HG50-8 suffix 'V'; 13T-26T ... 13,14,15,17,19,21,23,26
It looks like I am good to go with RD option (B). Not so sure about smooth shifting with option (A).
One encouraging bit about option (A): I have a build that currently uses a SunTour indexed FS on a modern production Shimano 6 speed (14T-28T ) freewheel. It changes on an MTB SunTour XC RD. Shifting is not perfect on every cog, but it is sufficient, except that I have to trim a Sugino 75 FD at the extreme ends.
You can see that my stuffs are Franken-builds, but that is because of budgets and the constraints around the rarity of vintage parts in this part of Japan. Also the expense and hassle of importing. Not that this is exceptional among a lot of BF members, I'm sure. I am not a purist-collector. My bikes are used to keep healthy and fit — plus I just downright love cycling and bicycles. Each build has a specific purpose. This proposed transmission above is intended for wide range ratios to be used for commuting and light-weight touring. I hope that members will offer their opinion.
I'd like to do perfect group-set builds, but until I win the jackpot, the deal remains thus: as long as it does not look dork-like and vintage-heretical, and as long as it works — OK!
WHEW! Just had another quake here ... but nothing has fallen down!
