The test wheel was on the Suzuki BMXA ran. You can see the Suzuki drop out in the photo. I ran across an NOS one a couple years back and SOD has it on one of his builds.

 

I remember them always dragging somewhat.

I've seriously considered picking up one of those Atoms for a '77-'78 build.....HEAVY or not. :)

Here's the BMXA Suzuki that Ben is referring to on the cover of the June '78 issue.

Check out the tasty rear rim....one of the elusive 2.125 Araya 7L's:

The Addicks sprocket test in that issue uses the same Suzuki GVX used in the Atom hub article. :wink:

I know I have a good pic of the hub Ben found me for the Matthews but I can't find it right now. :unsure:

I bought a Kos that was modified into a mountain bike a while back. It had an Atom hub laced to the rear 7x. Someone told me that a fair number of mtn. bikers were using them in the late 80's.

I've got one laced into a red Araya 7B that I think may be from Greg Grubb's FMF from the Nebraska scene in the mid '70s.  Can't confirm it though.  Always looking for photographic evidence to confirm/exclude.

I'm shooting for an Atom/7B setup for my 75 Squareback project. Love that combo.

Today I’m working on a 1969 Schwinn Lemon Peeler with an Atom front drum hub. Here’s some pics for reference. Pretty simple design, and it works great.
