Aherns NC Dually : Update

November 19th, 2008 by Arleigh

The other morning my blog feeder spit out information about the Aherns full suspension bike that has been in the works for a very long time.

It seems that Mike has teamed up with Devise Solutions to help build his brand and network out.  This has also caused some back time (but long term up time) in the design/build process of the bike.  With almost 24 CNC parts to make I hope he has multiple CNC teams in line!

From the blog :

Here is a brief overview:

  • Constructed with 7005 aluminum alloy
  • Compatible with both 26″ and 650B (27.5″) wheel sizes
  • 150mm rear wheel travel achieved through modified four-bar linkage
  • Rear axle path moves in an upward/rearward direction
  • Zero chain/chainstay growth is achieved through ‘Semi-URT’ design
  • Low BB height also achieved through ‘SEMI-URT’ design (as rear wheel moves through its travel, the BB height increases for additional crankarm-to-ground clearance)
  • Concentric rear-axle pivot minimizes brake jack
  • Designed around Fox 15QR front fork in 140-150mm travel range
  • Compatible with Fox RP23 and Fox DHX 5.0 rear shocks (7.875″ overall length and 2.25″ stroke)
  • ISCG-05 mount comes standard
  • Shimano Direct-Mount front derailleur (uses ISCG-05 mount)
  • Front derailleur follows swingarm path for superior front shifting
  • Shimano Press-Fit Bottom Bracket shell > 92mm width
  • Shimano Press-Fit bearings used within Main Pivot housing
  • Rock Shox MAXLE 12mm bolt-thru rear axle system for superior stiffness
  • 135mm rear hub spacing
  • Rear ‘international standard’ disc mount
  • Hand-formed rectagnular chainstays maximize heel clearance
  • Front triangle has low standover height and low center of gravity
  • Widest bearing spacing possible at every pivot point; ENDURO MAX bearings used throughout
  • Interrupted seat tube enables rocker arm to pass through for shock actuation
  • Swingarm components easily serviceable
  • Replaceable rear derailleur hanger
