I’ve been in the market for more higher end bike trainers and was intrigued by the two Elite trainers sold at REI until I saw the Warning posted for California residents.  The link takes you to a Proposition 65 website that lists cancer causing chemicals that the state requires companies like yours to report if associated with a product.  I contacted the state program to see why these Elite trainers were flagged, and they responded that I would have to contact the manufacturer.  REI must know the reason.  As a consumer, I’d like to know what the risks are in using these products and wonder if you can help me determine the risks.
