Kool Caps 

Kool Caps are a product designed to easily make the modernized new school 20" Skyway Graphite Tuff Wheels, and 20" 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.

Gen 1 Kool Cap Gold

Generation I, And, new Gen 1.1, Kool Caps:

  • Gen I Kool Caps have the sharp corners. And, remain for installation onto 20" Graphite Tuff wheels with all metal convertible hubs.
  • Designed to emulate the original 20" Graphite Tuff wheels of circa '79 to '81. Which had genuine Campagnolo precision loose ball hubs installed on them.
  • Generation 1.1 Kool Caps, are Gen I Kool Caps evolved: All of the latest Gen 1.1 Kool Caps have undergone additional machining processes. Both versions of Kool Caps are all completely plug and play now to their respective wheels. Modification to the front wheel is no longer required to install Gen 1.1 Kool Caps onto current 20" inch Zytel Nylon Tuff Wheel II's.
  • All other colors have now sold out.  Gold is the only color available.
  • Production costs have risen substantially. None the less. I am still pricing them at the original Kool Caps release price of $40 per set.

Gen 2 Kool Caps Gold
Generation II Kool Caps: Are: Out of Production
  • 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, the laser cut Gen II KC's are currently out of stock in all colors. Rising production costs, and minimum order quantities, have made Gen II's become inviable.  With an insufficient ROI, they will likely remain out of production.


Kool Caps history and trivia:

  •   Kool Caps 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 original Tuff I wheels had solid plastic hubs. And with coaster brakes, they had a tendency to overheat and melt. So, metal flanges were designed to add airflow. And, dissipate heat on the next generation coaster brake Tuff II Wheels. The coaster brake hubs installed in those original metal flanged wheels were named "Kool Hubs". Kool Caps seemed the logical extension of the original Kool Hubs.
  • The first Kool Caps were hand machined on a Bridgeport type mill, and a rotary table, using "Old School" methods of hand crank machining, as a fun project.
  • Now, Kool Caps are being made using modern dies, and other 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.
