If you are looking to change out your Surly Pugsley fat bike frame, the Surly Wednesday would be a great choice. The Wednesday differs from the by:

  • Centered 177 vs 135mm offset rear spacing
  • Stronger frame, but not much heavier
  • Bluto compatible
  • Thru axle compatible
  • More ‘neutral’ MTB Geometry vs ‘classic’ XC Geo
  • Internal cable routing for a dropper post
  • Increased tire clearance—will fit 4.6 tires on 80mm rims @ 445mm RC (10mm back in dropout)
  • 435–455 (Wed) vs 448-473 (Pug) chainstay length
  • Longer Effective Top Tube measurement
  • Increased standover (shorter seat tubes, seat tube gusset)

The Surly Wednesday is expected to be available late October, early November. Read more about the Surly Wednesday on the Surly website.
