CPSC campaign 15118
Hazard
An open quick release lever on the bicycle's front wheel hub can come into contact with the front disc brake assembly, causing the front wheel to come to a sudden stop or separate from the bicycle, posing a risk of injury to the rider.
Remedy
Consumers should stop using the bicycles immediately and contact an authorized Trek retailer for free installation of a new quick release on the front wheel. Trek will provide each owner who participates in the recall with a $20 coupon that is redeemable by December 31, 2015 toward any Bontrager merchandise. (The coupon has no cash value.)
