Melissa’s Fatcycle

This fatbike will be really fun to ride. I pushed with normal chainstays here so am “only” using the Specialized Ground Control 4.6″ tire on the rear to give some room on the 430mm chainstays.  A Surly Lou 4.8″ fits but with not enough room for comfort. Orange Nextie carbon tubeless ready rims, Surly Bud on front, tires are both run tubeless. Hope Fatsno hubs with a 197×12 rear and a 150×15 on front for the Bluto 120 fork.  Shimano XTR shifter and brakes and rear derailleur, Race Face Turbine Cinch crankset with a direct mount 28t ring, a wide range 10-spd cassette with the 42t Wolftooth cog and their 16t as well.  A Thompson Covert dropper post will be put on when it arrives which also has internal routing like the rear brake and derailleur.  She wanted something camo but also dug this Cosmic Blue so I got some orange camo decals made up by VCG.  I think it looks pretty awesome!

Geometry is short chainstays and slack head tube angles, my new fatbike preferred geometry because of how it behaves in soft snow. Here goes:

– 68.5 degree HTA

– 73.5 degree effective STA

– 430mm (16.9″) effective chainstay length. Actual is about 434mm. In my mind, effective length means more than actual. Effective is the horizontal distance between the rear axle and the center of the BB.

– 62mm BB drop is nothing too high or low. I’ve been leaning higher lately to reduce pedal strikes with such wide Q-factors that now are common (222mm!) and when using flat pedals.  Having said that…this still is a pretty low BB at about 318mm (12.5″) with the biggest diameter fatbike tires.

– 610mm (24″) effective top tube, 720mm front center.
