The Extant Seven bikes designed by Ride Studio provide everything you could want in a bike:  Value, durability, light-weight, high-performance — and to own it today!

Choosing your Extant bike model is the first step, of three, to getting your own limited edition Extant bike.  The first step is choosing your bike model.

The Extant RedSky is the lightest high versatility bike on the market.  It’s a true performance road machine that is equally at home at any New England road race or doing 200k at the D2R2 dirt road ride.  It’s difficult to find one bike that can do so much.  The RedSky Extant is that bike.

Why is the Extant RedSky UMC the ideal bike?

  • Lightest Extant Model:  By just 2 ounces of the RedSky RMC.  About 1.3 lbs lighter than the Evergreen UTD.
  • Tougher:  The UMC is the toughest RedSky model.  The Ultegra parts can typically take slightly more abuse than the RMC’s Rival parts.
  • Best Travel Companion:  This bike employs Shimano’s Ultegra 6800 parts specs so this is a great bike if you travel — because any bike shop in the world will be able to work on and replace parts on the UMC.  The mid-reach brakes also make packing and unpacking this bike really easy.
  • Longest Service Life of all Extants:  The Ultegra kit, overall, is likely to wear a bit longer than the Rival kit on some Extants.  The caliper brake’s simplicity also leads to longer overall life compared to a typical, more complicated, disc brake system.  It can vary greatly depends on how you ride, where you ride, and how tough on equipment you are.
