Delta 7 Arantix Mountain Bike

Looking for the lightest bike frame you can find? You'll be hard-pressed to find one lighter than the Delta 7 Arantix Mountain Bike ($TBA). Featuring a patented IsoTruss carbon fiber and Kevlar open lattice tube design — correctly described as "spider web-like" — this off-road beast weighs in at just 2.74 lbs., and can be ordered frame-only, or outfitted with SRAM or Shimano bike components.
