Houston, we have a problem…. I bought clockd’s XC9000 hubs which came all the way from New Zealand and the lock nut to lock nut width on the rear hub is 126mm and the distance between the drop-outs on my SM500 frame is 135mm
. Looking at the Suntour catalogue the rear hub was available in 126mm or 130mm, so I’m going to put a post up in the wanted section for a QR axle and spaces and see if that will work. Any thoughts? I'm guessing the Suntour thread is the same as a Shimano one (although I haven't tested it)
as I need to use some of the parts currently on the Suntour axle (to fit into the cartridge bearings).
All this is suggesting to me that not all ’87 SM frames are the same. I’m thinking that the Suntour equipped frames (SM900 & SM800)
would have had narrower stays than the Sansin and Maillard equipped (SM600, SM500 & SM400)
models as there are a few Shimano equipped bikes out there and that's 135mm.
No luck with the front mech yet.
