Product Overview:
The inside black portion of this wheel is made from molded polycarbonate plastic. The outer tread is TPU (thermoplastic polyurethane) with a 60a durometer hardness. 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. Two bolt circles are included on this wheel, with an inner bolt pattern designed for use in FTC applications and the outer pattern designed mainly for FRC uses.

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

Wheels performed astoundingly well on FTC Res-Q painted ramp, much better than standard Stealth Wheels.  Enabled scoring in middle and upper buckets.
