    Higher Range Cogset for 1987 Traveler

    I have a Maillard hub and an Atom 77 freewheel with a 14-15-17-20-24-28 cog set. These gears are much too wide of a spread and I have never once used the 24 or 28. Is there a freewheel out there that I could install in the 13-23 range?
    If so, where would I be able to purchase one?

    I understand that classic and french parts are not exactly easy to come by but I would prefer not to replace my hub.

    You've got a few options. First, go to your LBS, they might have a tighter freewheel on hand, plus the tools to install it (it's not really a job you can pool off with an old spoon, a multitool and a hammer - dedicated tools required!). Second, find a used wheelset with a maximum of seven cogs (due to axle spacing) on CL or ebay, they are usually cheap an plentiful. You can keep the old set on hand to keep the bike complete and original.
    Pass the Dutchie on the non-drive side.
    Rather a 100$ bike with 1000$ wheels than a 1000$ bike with 100$ wheels.

    Do you know if your hub/freewheel are french or english threaded? If english threaded, finding a replacement freewheel, new or used, will be a snap. I suggest you find a gear ratio calculator online, and calculate the ratios that you currently use, then try to find a replacement that covers the same spread, with as many fairly evenly spaced ratios in between as possible. If you're at all mathematically inclined, you can work out the calculations yourself in Excel or the back of an envelope. There's more explanation in post #16 in this thread: http://www.bikeforums.net/showthread...ng-my-Univega!

    Thanks for the input, guys!

    I went to a shop today that carries only classic parts and they had bins of old freewheels and cassettes. I learned that it is an English thread so a lot of them will pop right on. They believe there is room between my 14T cog and the drop out for another gear. I'd love to run a 7 speed but it seems that the majority of the freewheels I looked at had a much narrower chain profile. I'll keep scavenging.

    If you get a 7 speed freewheel that fits your hub & axle and doesn't interfere with the chainstays & seatstays with the chain mounted then yer good to go. Just make sure the chain is the correct width for the freewheel (7/8 speed chain should be correct).
