Kool Caps 

Kool Caps are a product designed to easily make the modernized new school Skyway Graphite Tuff Wheels, and Tuff Wheel II's, look like the original Graphite Skyway Tuff Wheels from the early 1980's. Allowing riders to preserve expensive original wheels, while remaining old school cool.


Generation I, (And Gen 1.1), Kool Caps:

  • Gen I Kool Caps have the sharp corners.
  • Designed to emulate the original Graphite Tuff wheels of circa '79 to '81. Which had genuine Campagnolo precision loose ball hubs installed on them.
  • Generation 1.1 Kool Caps evolution: All of the latest Gen I Kool Caps have undergone additional machining processes. They are all completely plug and play. Modification to the front wheel is no longer required to install Gen 1.1 Kool Caps onto either type of current 20 inch Tuff Wheels. This includes installation on the new school Graphite Tuff Wheels, or Tuff Wheel II wheel sets.
  • Due to current production cost increases, and, minimum production volumes. The Gen 1.1 Kool Caps will soon only be available in original Gold color.
  • Red, Blue, and Silver colors have also been updated to Gen 1.1 "plug and play" status. But, will only be available until the current inventory is gone.

Generation II Kool Caps:
  • Gen II KC's have the rounded corners.
  • Designed to emulate the subsequent generations of original Graphite Tuff Wheels and Tuff Wheel II's produced circa '82 and later.
  • Gen II KC's have always been plug and play, with no modifications to the wheels for installation. Including Graphite Tuff Wheels, and Tuff Wheel  II's.
  • Unfortunately, Gen II KC's are currently out of stock in all colors. Additionally, acceptable production costs have become unattainable at this time. Although I intend to continue to pursue the issue.


Kool Caps history and trivia:

  • They were born from a "what if" discussion on Vintage BMX bicycles.
  • The name Kool Caps was spawned from the original Skyway Tuff II coaster brake hubs. The metal flanges were designed to dissipate heat on the original coaster brake Tuff II Wheels. The coaster brake hubs installed in those original metal flanged wheels were named "Kool Hubs".
  • The first Kool Caps were machined on a Bridgeport type mill, and a rotary table, using "Old School" methods of machining, as a fun project.
  • Now, Kool Caps are being made using modern dies, and machining techniques. Never the less, Kool Caps are still not a high volume item. And manufacturing prices, supply, and demand, continues to evolve. The pricing will never match a mass produced item's pricing scale. But they truly remain a "For Fun" item, at a "For Fun" item price.
