I have a working GH6 and I'm trying to decide what to do with it. It's a 36 holer and I have no idea what bike it originated from so I don't know how fast it needs to turn to make good light. I had been kicking around the idea of making a wheel with it for my Hybridized Alpine Monitor Pass MTB; however, I just scored a 36 hole Shimano DH-3N71 off of E-bay that I believe would make a better fit for that bike. I have two other bikes that it might work on, a Work in Progress Raleigh Twenty or my '07 Specialized Sirrus 700c Hybrid. The Twenty I'm thinking would be a better mechanical fit as it is from the era of bolted on front wheels and there would be no way of fitting a quick release axle to the GH6 (at least not with a modern cammed quick release, a set of giant wing nuts, yes I know that much.) The only thing that I'm twitchy about is it adds a lot of drag to a high geared small wheeled bike. No matter what this bike is going to require a wheel build up either with this hub or with a conventional front Sturmey Archer hub.
As for the Sirrus the rear wheel is a 32 holer and I think it would look weird to have this old battered and rusting hub with a slighter denser spoke count on the front wheel of a brand new bike. I'm thinking that If I put a dynamo on this bike it's either consume a fifth of JD and buy a SON hub, or weasel and put a a bottle dyanmo like a Dymotec 6, or a Spanniga Vesta on it via a Zinkens Bracket.
