BMX cassette driver hubs don't have interchangeble cogs, the cog and the freehub body are one piece. That allows them to run something like a 9t(!) rear cog on the microdrive setups currently popular with BMX'ers.
The SunXCD 5spd, 120mm cassette hub first appeared on the radar about a year ago (just after the Taipei show?), but it seemed like it was only available in Asia. Now it seems Merry Sales has set up a import deal with them, but the stuff hasn't appeared on US shores yet. I'd expect it to appear sometime this year, keep an eye on the Soma/Merry blog or ask your local LBS with a Merry Sales account to keep an eye on the monthly flyers that Merry sends out. I want them to mate the 5spd cassette body to 130 or 135mm spaced hub, with appropriately wide and symmetric flanges. Or maybe I'll try the cassette SS with many cogs thing one of these days. Ira Ryan put 4 of 8 on a CK hub on his Oregon Manifest bike a couple of years ago: http://www.flickr.com/photos/iraryancycles/6190450769/in/faves-85709120@N07/ On Tuesday, April 16, 2013 2:43:34 PM UTC-7, Jay B wrote: > > you're right, Keith, the 130mm isn't a drastic move at all. i have a 105 > hub that slides right into the dropouts on the QB. i'll look into those > Profile Racing 120mm hubs.
