Subject: [CR]Converting BMX hubs to road

Jerry asked:

Is it possible or practical to convert BMX hubs to road use by changing the axle, assuming one wants QR? Was the thread on old BMX rear hubs the same as freewheel thread, or more like a track cog?

Jerry,

The shell of a typical BMX hub should work for road freewheel use. As you suggested, the parts were often road parts that were modified for BMX use, and I'm pretty ceratin that was typically the case with BMX hubs. As such, the general configuration of the shell, including the flange spacing and threading should be the same. As I recall, the thread is English.

One point to look out for is that the spoke holes may be drilled larger on a BMX hub. Probably not a problem if you use 14ga or 14/15/14 ga spokes. The rear axles are unlikely to be 10x1, and are more likely some 3/8" or 9.5mm spec, with oddball threading (24 tpi?) that descended from the days of coaster brake use in BMX... but that's mostly specualtion on my part. Point being... you probably will need to find a complete rear axle set that is compatible, rather than reusing the cones and locknuts on a new hollow axle and adding spacers.

Check your Sutherland's for more info... I'm sure it's in there.

Good luck

Occasionally, as with the almost complete 50th Anniversary Paramount project, I seek components in anodized colors, gold in the case of the Paramount. It seems this is more common in BMX components than classic road components.

Since I am pretty much totally ignorant of BMX stuff, I'm hoping someone with more familiarity can help me here. Is it possible or practical to convert BMX hubs to road use by changing the axle, assuming one wants QR? Was the thread on old BMX rear hubs the same as freewheel thread, or more like a track cog?

It seems that when BMX first developed at around the end of the On-Topic era, many manufacturers took their existing classic road components and adapted them to BMX use, often giving them anodized finishes that they imagined would appeal to the BMX crowd. I'm looking to reverse the process and bring a few bits back from the BMX realm into the classic road world.
