Hi,
I recently bought a Maillard 700 freewheel without being aware that it is a compact one.
There is very little info on these FWs on the net. There seem to have been two types of these. I have the type with (outer to inner) two screwed cogs - one notched cog - one screwed cog - two notched cogs. The threads do not fit any other Maillard FW I have, so I can reuse only the notched cogs.
I ride my bike with a treasured stock of old Sedis Silver chains, which seem to be somewhat wider than the current 6/7/8 sp chains. Just hanging a chain over the freewheel indicates that it is a very close shave and that there is little room left for bending the chain towards the front derailleur.
Do the Sedis chains fit nonetheless? I don't want to experiment with a real ride, fearing that the chain might get stuck and cause damage to the freewheel and to itself.

| I'm more familiar with Suntour than Maillard freewheels, but I think the spacings are the same. The 6 speed compact freewheel is to get 6 speeds in the space of 5, and requires the narrower 7-8 speed chain. Somebody more knowledgeable please correct me if I'm wrong on this. |

Hi vanhelmont,
looks like you're right. I tried a newer 7sp chain and it hat visibly more space to the sides, while a 9sp was to narrow and looked like it might get stuck between cogs under strain, at least if I put the "normal" Freewheel back on. So I'll have to think if I go for another chain or if I just ditch the FW again. But it is a nice one with a ratchet sounding much like modern campys, saves you a bell.

Thanks Christoph. I taught Chemistry and general Science for several years. He was an interesting guy, and did a couple of things that make good examples in class.

| Great, I am a chemist and have held lectures on the history of chemistry as part of my job while working on my thesis. So the name immediately struck. |

Greetings,
Some of best chains that I've found are the latest style SRAM PC-8xx series:
PC-830, PC-850, PC-870 & PC-890 chains.
They work with 6, 7 and 8 speed freewheels and cassettes plus old 5 cog freewheels too.
The higher the number the fancier the chain is (nickel plating and so on). The PC-850 are inexpensive and work great. |

+1 on this - I used the PC-830 and PC-850 exclusively. |
