Vintage Shimano rear hub/freewheel compatibiltiy
I guess I'm looking for a true Shimano Guru. I'm looking on Ebay to find a replacement freewheel for a Shimano 6 speed thread on hub from the '80s. The rest of the group is Arabesque? Anyway; I found this model MF-6207, 6 speed freewheel http://cgi.ebay.com/Shimano-600-6-sp...QQcmdZViewItem and I'm wondering if it will fit my hub. Probably? I guess I need to know if most Shimano thread on stuff is compatible? Or did they change thread sizes or other spec's, depending on the model year?
I'm not a guru by any means, but it'll fit. Freewheels were the products that Shimano used to really break into what had been a European component market, so they had to make them "non-proprietary" to fit other maker's hubs. A brand new freewheel bought today that will thread right on in place of a freewheel from 30+ years ago.
You can use Suntour freewheels just fine, particularly if the hub has English threads (1.370 x 24 tpi), which it most likely does. Even Italian-threaded freewheels will work, but I've heard you shouldn't keep switching back and forth. Suntour made a lot of different freewheels: 120 mm OLD in both 5 and 6 (the latter Ultra), 126 in 6 and 7; I don't know what if anything in 130. I believe that all the "Winner" models are built on the same basic unit, with the difference being the cogs and spacers. They all take the same chain width, so you don't have to fret about that. I have a couple New Winner Ultra-7s and I like them a lot. They are basic, don't have all the fancy tooth shaping, but they shift well, and they're very durable; plus I like the sound they make.
