steel 29er for Colorado with rocker dropouts

 The rocker dropouts from Paragon Machine works make this frame versatile. The chain tensioning option allows for single speed and internal geared hub uses. Also, the zip-tie full housing setup for the gears will work with just about anything.
 The tubing is my current favorite blend of Ture Temper OX up front and Dedaccai in the back with Nova wishbone seat stays. The wishbone has been part of my MTB frames since 1987 and it is still the best way for me to get the structural rigidity that suits disc brakes. The stays also allow for better tire room on smaller frames with large wheels.
I added water bottle mounts after the photo was taken. I was running out of daylight and wanted to have a photo up tonight.

Single speed belt drive road frame for Bakersfield

 This steel frame has a light Columbus life rear triangle so in spite of the belt splitter and the tapered head tube, this fairly tell frame is only 4 lb. 2 oz.
 the brake bridge height is optimized for the wheel at mid-dropout, around 411 mm from the BB center. This would be a bit long for a road racing frame but nice for a townie. this bike will mostly see city use for commuting and short trips.
