need help finding chain for 6 speedandydave
Jun 9, 2003 3:09 PM
I was hoping to get help finding a good chain for an old 6 speed. Not sure what is compatible (components are campy record if this matters). What is a good choice, and where can I find it? Thanks
SRAM, lower end model, P58 or 48, Nashbar, PerformanceLone Gunman

or the LBS. I use srams on my old 6 and like them due to the ease of cleaning off the bike with the power link. Don't get a 9 speed, too narrow.

Any modern chain except a 10 speed will work, but super narrow chains are unnecessarily difficult to use with 6 speed. Look for a SRAM designed for 7 speed. Also, the KMC website has specs for all its chains, which includes the length of the rivets. The chains with the longest rivets will be easier to join and probably shift better on 6 speed. Or you could get a new old stock Regina Oro on Ebay for the perfectly restored look.

A "modern" chain will work just fine. You have a wide selection of possible chains, though SRAM units are reasonably priced and come with a convenient SuperLink-type connection. Watch for sales.

or will neeed at least an "8-speed" chain (really, 7/8 speed chain). Some rings have just enough space between them that a 9-speed (or even some of the narrower 8-speed chains, such as SRAM pc-48,58, and 68) will drop between the rings. What a pain, especially if the powerlink is caught! You gotta pull the rings off to get the chain out!
Try buying an SRAM chain (PC-68's are quite good), but if you drop chains between the rings, Shimano I-92 (may have that # wrong, BTW) are just a hair narrower, so they might work better.
Or maybe you won'tKerry

The difference in width between my Record 9 chain and an old Regina chain is about 1/64 of an inch (0.4 mm), and neither chain will come anywhere near fitting between the chainrings on a Campy NR crankset (vintage 1972). A narrower chain may have a tiny bit more tendency to ride on the edge of the chainring and not engage the teeth of the small ring when downshifting, but it will not fit between the rings.

I have an old Cannondale 6-cog touring bike, with a Sugino triple crankset, and TA outer rings, in the sizes of 32/48/52. Back when I had 50/54 on the outer rings, SRAM chains worked fine, but since installing the TA rings, the PC-68 I had been using suddenly started getting caught between the rings almost every day. I switched to a Shimano I-91 (I think....) chain, mostly because it was just ever so slightly wider, due to those plates that stick out. Since that day, I haven't dropped a chain between the rings. Oh, BTW, the chain is quieter, and it shifts better. Not bad for an extra $10, is it?
Most likely a Shimano HG chain, not IG chainrussw19

However the real difference between these chains in simply the bulge in the plate designed to catch the shifting ramps and pins on the chainrings and cogs.

But for anyone interested... here's some widths of chains...

Shimano 9 speed chains are 6.6mm

Shimano IG chains (obsolete, Last used for Mountain Groups between '96 to '99) 7.1mm

Shimano HG 8 speed chains are 7.4mm (again, due to the bulge in the outer plate.)

Most SRAM chains are 6.9mm wide, but some are slightly wider at 7.1mm for all their 5 thru 9 speed chains. The exception is the hollow pin chains the 89R is 6.2mm the 99R is 6.4mm

Campy 9 speed chains are 6.8mm

Campy 10 is 6.1mm

8 speed Rohloff Chains are 7.1mm

9 Speed Rohloff Chains are 6.8mm

Connex 6,7,8 speed Chains are 7.2mm

Connex 9 speed Chains are 6.8mm

Connex 10 speed Chains are 6.2mm

That should be everything you wanted to know about chain width.

SRAM 6,7,8 speed chains work just fine.russw19

I have a bike that uses 6 speed Campy Super Record... I run a SRAM PC-89 8 speed chain on it and it shifts better than wider chains.

thanks for replies, I learned a lotandydave
