Trek has announced the immediate recall of a number of 9.8 Superfly FS SL, X1 and XT bicycles because of a reported fault on some Bontrager carbon seatposts.
According to a report on the United States Consumer Product Safety Commission website, the Bontrager Carbon seatpost on certain bikes may "crack and break, causing a fall hazard to the rider". Two incidents have been reported to the company, although Trek said no injuries have occurred as a result of the fault.
Around 330 bikes are believed to have been affected: Trek Superfly FS 9.8 SL, X1 and XT with serial numbers ending in J or K, which are located on the bottom of the bicycle frame. They were imported into the US after being manufactured in Taiwan and were sold between September 2014 and July 2015 across the States.
If your bike is affected, Trek advises that you should cease using it immediately, and contact an authorised Trek retailer who will provide a free replacement seatpost. Trek is also providing a $20 'goodwill' coupon, valid until the end of December 2015, which can be used towards any Bontrager merchandise.
