Listing Update...This is my last one in this model/finish/size and while it is new-old-stock (and shows no signs of lacing), it does have some shopwear...scuffs and scratches...and please keep this in mind when considering this offering.
This offering is for a new-old-stock Shimano 600 UniGlide 7-speed freehub (model FH-6400). This is a late 80's freehub with 36 holes and 126 mm (locknut-to-locknut) spacing. It's a top-end freehub model from this era (with only Dura-Ace considered better) and is finished in a polished silver. We can also confirm the freehub body is an older Uniglide model that will accomodate 6/7-speed UniGlide cassettes (but is a candidate for a HyperGlide hub body swap, as described in more detail elsewhere in this listing).
Shimano literature further indicates this model freehub has a one-pieced forged aluminum alloy design...so a very strong and durable offering that should hold up well under stressful conditions.. This same reference material also indicates the cup-n-cone bearing design is enhanced to include some sealing properties that should help reduce internal wear. Now I will be the first to admit these sealing properties are not on par with more current cartridge bearing designs, but I believe Shimano's claim still holds some merit.
As for condition, this is a new and unused freehub with no evidence of lacing on any of the spoke holes. The freehub is not retail boxed, so expect some shopwear (as noted in the listing update above), but overall the freehub still shows fairly well and includes a factory matched skewer.
HyperGlide hub body swap information...
We've had a number of customers ask us if these hubs are a good candidate for a HyperGlide freehub body exchange (since the 126 mm spacing is so rare in a nos Shimano freehub in any model...so it might be worth the effort). We have not attempted to do this, but all our research indicates these freehubs do have Shimano's interchangeable hub body parts that will allow for the replacement of the existing UniGlide hub body with a HyperGlide hub body. From what we can tell, after you remove the axle, there is a hollow fixing bolt that requires a 10 mm allen wrench. This bolt has conventional threading, so it should unscrew with a counterclockwise turn of the wrench...and once removed, the freehub body should be loose and may be uninstalled. Our understanding is the HyperGlide repacement body should install in the same manner.
I guess the one area where problems may result is the right side cone and dust cap that helps to hold the bearings in place may be different...meaning these UniGlide hub bodies may have slightly different cones/dust caps compared to what is needed for the HyperGlide replacement body. We believe some customers have worked around this problem by using the necessary HyperGlide freehub parts from an otherwise worn out HyperGlide freehub (where the handful of parts needed to do this exchange are still serviceable). We're not exactly sure on all the details here, but we still thought the above information might be helpful to those considering one of these freehubs for such an exchange.

Note to international customers regarding shipping...
We apologize to those that feel some of our international shipping charges are too high. We only charge actual shipping rates, but once an order exceeds a certain amount, we hesitate to use the least expensive US Postal Services First Class International service. We feel this way, because this service is not trackable or insurable...so more risk of loss. We prefer the US Postal Services Priority Mail International service for more expensive orders, because this service is trackable at USPS.com and insurable...so less risk of loss. Unfortunately, this service is more expensive, especially for smaller/lighter packages, relative to the First Class International service. We are sorry about these higher shipping costs, but hopefully our notes help to explain why this is the case.
Note to international customers regarding customs...
We also apologize to those that feel their country import taxes, duties and brokerage fees are excessive. As a small US business, we are required by customs' laws to declare each order as a retail sale. Additionally, the declared order value must be equal to total store purchases and/or winning auction bids (less any shipping costs, as these are not considered in the declared value). As a result, each customer will be responsible for paying his/her own country taxes, duties and brokerage fees, which will be collected upon delivery. Again, we aplogize for these additional costs, but we cannot afford the penalties and fines that come with breaking customs' laws...so we have to strictly abide by them.
