Mad Dog Cycles is introducing for a limited time a cycling helmet trade in program, bring in your old helmet for a $20.00 credit toward a new MIPS equipped helmet (non-MIPS helmets are not eligible to receive the trade in credit). We will accept the trade in of any bicycle specific helmet (must have a CPSC or ASTM safety rating). Your old helmet will need to be surrendered to Mad Dog Cycles. This program will be available in March - April 2018. Why are we doing this: Bicycle helmets have a "shelf life" of approx. 5yrs. Safety standards evolve and older helmets may not meet the current standards. Helmets are a one time use, if you've had a situation where you've had an impact with your helmet it may need to be replaced.
