Product Overview: The inside black portion of this wheel is made from molded polycarbonate plastic. The outer tread is TPU (thermoplastic polyurethane). This robust but lightweight wheel provides good traction on carpet and soft tiles. The Stealth wheels are the perfect wheel for intakes and other auxiliary robot mechanisms. The bore of this wheel is available in many bores and durometers. 4" Stealth Wheels feature a bolt pattern on a 1.875" bolt circle for mounting sprockets, hubs, and gears. 8mm bore Stealth Wheels feature a bolt pattern found in most common FIRST Tech Challenge building systems. The grippiest of our wheels, the 35A green wheels should not be used as drive wheels and only for mechanisms and intakes.

Product Usage:
Many thread locking materials are not compatible with polycarbonate and can eat away at the plastic. Be sure to check which adhesives are okay to use with this product. This link will allow you to check which materials are okay to use with what adhesives, http://bit.ly/loctitematerialcheck

Easy, quick, and dependable March 21, 2017
Reviewer: Thomas Bredemeier from Bannockburn, IL United States  
Ordered our Stealth Wheels from AndyMark and received them the next day. Easy to find what we were looking for, and all of the billing / ship-to address fields were already filled in from our prior orders. Reasonably priced, and dependable, we will certainly order from AndyMark again. Thanks for the great service!

Great for gear grabbing! March 21, 2017
Reviewer: Mike Taylor from Plainfield, IN United States  
It would be nice if the hole pattern lined up with the hole pattern in the hex hubs am-0096 when on the same shaft.
