NAHBS 2013: 38 Frameworks’ 25-Pound Carbon Fat Bike, Plus SRAM/Shimano Crankset Hacks!
Based near Denver, 38 Frameworks is a sister company to Funk Cycles that’s focused on fat bikes only.
Above, the Hogback is a full carbon fat bike that’s completely made in house (other than the alloy BB shell). Frame weight is 3.5 pounds with an asymmetric rear end that allows them to run any tire and still have a ton of clearance. Retail is $2,400 in stock sizes, but they’ll do a little bit of custom sizing if necessary. $2,600 for frame plus the Carver carbon O-Beast fork.
Both it and an alloy version featured top end cranksets from SRAM and Shimano inside their 100mm bottom bracket shells. Click through to see how…
Tons of clearance for even bigger tires.
25.09 pounds. For a fat bike.
They managed to get both XTR and X0 (below) cranksets on the bikes by chopping the spindle and welding an extension insert in place. This lets them offer high end custom builds.
Just started producing the alloy model in January. $1,200 to $1,400.
