Crank Suggestions

So I've decided to go with a Shimano 600 tri color (6400) group to build up the Serotta Davis Phinney frame and fork I acquired. It's period correct and potentially a group this bike could have been built with originally. The only problem is, I would really prefer to use a 110mm BCD crank. The biggest cog the 600 rear der. can handle is a 28 and I'm a big fat baby who likes his low gears and lives in a town with with many sustained hills where a 53-39 isn't going to cut it. Is there anything of the same era and quality that anyone can reccomend?

An early 90s (?) Deore Triple has kinda/sorta similar look and a 110 BCD that can handle smaller rings. (obviously, you don't have to use the even smaller bolt holes intended for the third inner ring) There might be an similar Exage triple of that era that has the grey anodizing of the tricolor.

Yes, but Tricolor presents a challenge. You could find a Shimano triple of that era with similar shape and re-decal it.

I had the same thought and went with a Stronglight on a tri-color upgraded to 10 speed - has a similar look to stock.
The Stronglight is crap and I must get around to replacing it, I just don't ride that bike cause I don't want to deal with it.

if you want class, go with a TA Zephyr triple
Zephyr
or TA Carmina double (choice of bcd)

Alex's Cycle also sells the Sugino Mighty Tour

There are a number of attractive 110 bcd cranksets from the mid-late 80's that would work well, either triples or doubles. Sugino, S/R, Deore, perhaps even a MTB crank. Sugino also made a compact and triple crank that had the same shape as the tricolor arms, but polished.

If it were me, I'd give up trying to match the finish on the 6400 and just celebrate your great gearing.

Cool. Great suggestions. I'll keep an eye out at my local co-op. I've been pretty lucky there so far. Somebody seems to be donating bits of 600 tri-color and other high end late 80's/early 90's components every few weeks so I should be able to complete this without breaking the bank if I'm patient. My S/O was very understanding about another bike showing up in the apartment as long as it doesn't make a financial impact.

Are the old Sugino-made Ritchey Logic cranks from the right time frame? You'd be hard-pressed to find a better 110bcd crank, IME.

Sugino was the one who made the 110 BCD cranks commonplace, BITD.

You can also Use 110/74 MTB cranks fit the granny or Not , you choose..

And I promise they look better in person than in my crappy pictures.

P.S. I do have a 175mm set of Exage triple cranks at home, @InTheAether. If you're interested, perhaps we could reach an agreement offline.

I put a willow triplizer (from ebay) on a 600 crank, with 130 bcd - 50-40-30

Works great, but needed a 127 axle and a triple fd (used the always reliable MT-60)

In that vein, a Deore MT-60 crank is always stylish (110 bcd)

Good luck

Joe
