So if you haven’t guessed, I’m bulding another bike.  This time it will be a fully-rigid singlespeed 29er built from as many used parts as I can find.  Over the next several post I’ll share the build process and show the (hopefully) nice used parts going into the bike.

First, I found this “used” Kona Unit 29er frame at a very reasonable price.  The frame is butted steel, has nice-looking sliders and came with both singlespeed and geared dropouts.  The frame looks new and has perfect paint.  Not a bad start.

Precision measurements.  More to come.

I haven’t done one of these in a while, but here it is:

April 2008: 152.6 miles

138.0 miles of the total was single track on the M2, 49.8 miles of which was on the M2 after a singlespeed conversion. The remaining 14.6 miles was on the Gunnar on the road, roughly 10 miles of which was towing a trailing with a small person in it.

For those who are interested, the M2 was converted using a Surly Singulator with a 32 tooth chain ring, 18 tooth cog and SRAM PC-1 chain.
