This Felt B12 Triathalon bike has previously been used as a demonstration bike by our show and events team.

As a result of its limited use, the bike is showing some signs of light wear, with the usual build-up on the drivetrain. In addition, there are some small marks on the fork leg and down tube.

The bike remains in excellent condition and has undergone a thorough inspection by our professional mechanics. As with all our bikes, it comes with a 12 month Wheelies warranty, plus any additional manufacturer warranty which may apply.
