6 Spd Stuff??
 

Anyone know of a place that has NOS or used but good condition 6 spd stuff like Hubs, rear, front derailer, shifters...etc. I'd like to fix up my little trek.

I have been checking Ebay a little but not much stuff available...and it's a rain bike so I'd rather not spend a ton on it.

As far as freewheels, hubs, deraileurs and shifters, are concernered, there is Loose Screws, Harris Cyclery, and even Nashbar sells most of this stuff, new, and at reasonable prices. Any freewheel threaded hub will work, the spacing is the only part that changes. Derailleurs should be friction. What type of Trek and what issues do you have with the old components?

If it started life out as a 6 speed, then the spacing is 126mm. If this is the case, then you can almost certainly take any 7,8, or 9 speed hub and put it in with a slight stretching of the rear drop outs with finger pressure only. If the bike is really old as in 70s vintage (with white letter and no background panels), then it may have started life as a 5 speed with 120mm spacing. If this is the case, you may consider having a good (repeat, good) shop cold set the rear drop outs to 130mm spacing.

If the bike was set up for caliper brakes you can almost certainly convert to 700c wheels with only a minor brake pad adjustment. If the bike is set for cantis, you need to try a 700c wheel first as cantis typically don't deal with hieght adjustments nearly as well as calipers.

Bottom line, most of the old Treks can be converted to modern wheels and modern drive trains no problem.

ebay has a ton of six speed stuff . . . look under the Suntour brand.

Unless you insist on indexed shifting, try converting to a 7-speed freewheel. With some 6-speed hubs, the operation is as trivial as unscrewing the 6-speed freewheel, removing the pie plate spoke protector, screwing on the 7-speed freewheel, and touching up the rear derailleur stops. With others, such as my circa 1980 Campag. Gran Sport hub, you would also have to add a spacer or two to the right side of the axle and redish the wheel a bit.

the suntour stuff works well
