Two questions (2)

  1. Would a motorcycle helmet be considered to exceed CPSC standards?

  2. Would a a fixed gear also be considered a brake on the rear wheel?

As per USATRules

(a) Type of Helmet. All participants shall wear a protective head cover, undamaged and unaltered, which meets
or exceeds the safety standards of the Consumer Product Safety Commission (CPSC). Helmets manufactured
prior to March 10, 1999 must meet or exceed the safety standards of (i) the American National Standard
Institute (ANSI Z-90.4), (ii) The Snell Memorial Foundation (Protective Headgear for Bicycle Users), or (iii)
ASTM F-1446 or F-1447, and which is clearly labeled by the manufacturer as satisfying such standards.
Removal of helmet cover, if required for that helmet to meet such safety standards, shall constitute an
impermissible alteration in violation of this Section 5.9(a). Any violation of this Section 5.9(a) shall result in
disqualification.

(j) There must be one working brake on each of the two wheels.
