To summarize, these frames are adjustable geometry with 9.25" of travel, just under 7.5# frame weight w/o shock, 1.5 HT, 83mm/150mm spacing, single pivot with very neutral progression and excellent pedaling characteristics. Geometry adjustments let the head angle range from 63 to 65 degrees with an 8" fork and 13.5-14" BB height. The chainstay lengths are 17.75" for superior stability with an exceptionally light and stiff rear swingarm making it one of the best tracking frames available. The wheelbase for the small is 47.0" and for the medium is it 47.7". The 1.5 diameter headtube allows for a very low bar height and lots of adjustment range for fork height. They are 100% hand made by Frank The Welder of Sinister/Yeti fame in Vermont, USA.

**The first frame pictured is my personal medium FB10 frame with a super durable textured black powdercoat. The second (the one without a shock) is one that was won as a prize at one of the east coast races with a gloss black powdercoat.
