Warren,What are the hub dimensions?Width between spoke flanges and flange thickness?Greg C.P.S. I forgot to include $ 4.00 each for brass grease cups from LittleDearborn in Minneapolis.>>> "Warren D. Shoun" 06/18/98 09:28am >>>Greg I did basically the same thing....but I got the older internal brakehubs too,including the rims, for $40.00 each at salvage...the Honda Trail 90 or theKawasaki 250both are good....and Buchanan did a really great job....the stats on the 9guagestainless steel spokes are that EACH spoke can pull 1000 pounds! Thesespokes are theupgrade for the pro off-road bikes that take enormous poundings...shouldbe able to takeanything except a vertical crash!Warren________________________________________________________________________________

Greg I used the Honda Trail 90 Hubs. These are machined hard aluminum alloy castings.The hub hasthe following approximate dimensions. 6" diameter. 4" thick at the center bearings 5" thick with axle spacers 1 5/8" between the spoke flanges 5/16" to 1/8" tapered spoke flange 5/8" high. I have taken the time to completely finish polish these hubs, removing anypossible pit orfracture point. Buchanans is about 6 miles from my home, so based on my reading of Piet Newsletters,I askedthe guys at Buchanans about side loads on this wheel assembly. They treated mewith the kindnessone shows the helplessly ignorant and truly retarded, and explained that when theyfinish truing upand properly tensioning a spoked wheel with 9 gauge stainless steel spokes, thehub will fractureand disintegrate before the wheel will deform, as the wheel is rotating and thatthis is a 36 spokewheel, and that each of at least the 10 spokes top and 10 spokes bottom are continuouslyabsorbingup to 1000 pounds each of compression, extension and lateral loads. This is inaddition to theshock absorption of the bungee cords. It was their opinion that the only way Ican over side-loadthese spokes is if I insist on landing in a side slip with the brakes fully locked-upon touchdown.________________________________________________________________________________
