  1. Answer from our friend Karl at RaleighAmerica, who submitted the photo: “This is the freehub body that we use on the Raleigh XXIX singlespeed. It is installed from the Non-Drive-side by an 11mm allen key.”

  2. That’s a little foul. A part off some no-name hub from a bike (vs component) company? Raleigh doesn’t even give a spec for the hubset on that bike. I think anyone that said “freehub body” in their answer wins this one.

What do you think?
