So I got a vintage Miyata 312 with 52/42T cranks. I also tried out a Takara Olympian, but this Miyata was a much smoother ride.
Too bad about the Fuji Team having already been sold ...
I am not familiar with the Miyata 312 ...
Alfeng: You mention being able to bring the shifters into the 21st century... That is something that I will definitely want to do. I'm not trying to get sponsorship by doing the Tris, but I want to be able to shift without having to take my hands off. It is a bit more difficult if you aren't used to it.
So, I could do that by purchasing the
SunRace Freewheel + a pair of CAMPAGNOLO 10-speed
shifters??
Provisionally,
yes ...
BUT, because your Miyata may-or-may-not have a
SunTour rear derailleur, you may-or-may-not need to replace it with a Shimano rear derailleur ...
YOU will need ...
- the shifters
- downtube cable stops (these used to be included with the shifters)
- probably, new cables/housing
- and possibly, an 8-or-9-speed Shimano rear derailleur (many people say that the 10-speed Shimano rear derailleur is interchangeable) and/or 8-speed-or-narrower chain (if your Miyata happens to have a SEDIS Narrow chain then you should not need to replace it)
- PLUS tools ...
- UNLIKE the Shimano & SRAM shifters, Campagnolo shifters will work with almost any cable actuated front derailleur of any vintage + almost any chain which is suitable for the Cassette being used ... 8-/9-speed derailleurs have narrower pulley wheels than 5-/6-/7-speed derailleurs & the narrower cage of the "newer" derailleurs doesn't play nice with the wider chains which are typically used with 5-/6-/7-speed drivetrains I found that the 9-speed Shimano chain works well for most drivetrains when used with Campagnolo shifters, including with a 10-speed Campagnolo Cassette
- the current Campagnolo shifters use an annoying-to-me T-27 bit-or-driver ... you need one whose shaft is at least 4" long ... you can buy these on eBay (recommended UNLESS there is a hardware store that is near where you live), too, or probably at LOWES, ACE HARDWARE, etc.
- the older Campagnolo shifters use a 5mm Allen Wrench which has a 4"-or-longer shaft
I have found that the "best" (
as in "least expensive") cable cutters are found on HARBOR FREIGHT's "Chicago" (
orange handles) needle nose & lineman's pliers & "dikes" -- a "set" of pliers costs about $8 when they are on sale ... it is probably worth going to Harbor Freight for the generic (
non-bicycle specific) tools.
A FLAT or Half-Round file is good to have to debur the end of newly cut cable housing.
THE PROCESS. If you limit the updating to using Campagnolo shifters, then the process is much EASIER than the following might suggest AND you will probably spend more time unwrapping-and-(re-)wrapping the handlebar tape ...
- unwrap the handlebar tape
- detach the brake cables from their respective brake calipers
- remove the brake levers
- attach the new shifters to the handlebars
- remove the downtube shifters & detach the cables from their respective derailleurs
- attach the downtube cable stops
- measure & cut the cable housing (I generally use coiled BRAKE cable housing for my derailleur cables)
- lube the cables with a dab of Vaseline-or-equivalent (recommended) OR White Lithium Grease
- insert (!) cables in the shifters (frayed ends are your enemy ... if necessary, create a "leader" by wrapping the ends with some clear tape) & into the housings ...
- tape the cable housing onto the handlebars with EITHER masking tape OR packing tape (I recommend that unless you replace the cable housing every month, then do NOT use electrical tape)
- attach the cable to their respective brakes/derailleurs
- adjust the cables (consult www.parktool.com or YouTube if needed)
- wrap the handlebars with the (new-or-used) handlebar tape
- test
- adjust, again, as necessary
- DONE!?!
A "work stand" of some type is beneficial ...
- some people suspend their bike from hooks attached to cords hung from their ceiling ...
- I have both a cumbersome Park Tool stand & a simple Y-stand which simply holds the rear wheel off the ground which I use 99.999% of the time
-------------------
Chris Juden's matrix probably tells 99% of the story ...
Indexed
7-speed Cog spacing &
8-speed Cog spacing are essentially the same ...
- The "old Dura-Ace" column heading means that the rear derailleur cable is attached at 9 o'clock ...
- The 'Hubbub" column heading means that the rear derailleur cable is attached at 3 o'clock (as pictured) ...

- http://www.ctc.org.uk/cyclists-library/components/transmission-gears/derailleur-gears/shimergo (a more-or-less updated article)
Here are some suitable shifters on eBay ...
- http://www.ebay.com/itm/New-2014-Campagnolo-Veloce-Power-Shift-10-Speed-Ergo-Lever-Silver-Alloy-Shifters-/301171257931?pt=US_Shifters&hash=item461f34b24b (new) ... Velo Mine also has similar shifters on eBay, periodically.
- http://www.ebay.com/itm/Campi-Centaur-10-x-2-shift-brake-levers-/301179361530?pt=US_Shifters&hash=item461fb058fa (used ... this is just an example)
FYI. The RAMPING compensates for any imprecision to the point where I tried using 9-speed Campagnolo shifters with a 9-speed Shimano Cassette. The result was simply that ONE intermediate Cog simply by-passed by the shifter & effectively making it an 8-speed bike ...
I also tried the 9-speed Camapgnolo shifters with a Ramped. 8-speed Cassette & an UN-Ramped 8-speed Cassette ... it worked fine with the former & did NOT work with the un-Ramped 8-speed Cassette.
Because the Ramping on the Cogs cures virtually ALL indexing imprecision when Campagnolo shifters are used, I suspect that the 11-speed shifters may be "okay" without using any alternate cable anchoring ... the
caveat being that the pulleys may wear out prematurely if the indexing isn't aligned "perfectly."
That's a good looking Olmo, Alfeng!
Thanks.
