About 1,800 Specialized Bicycles with Stout cranks are being recalled.

A statement from the U.S. Consumer Product Safety Commission said the driveside crankarm can disengage and cause the rider to lose control, posing fall and injury hazards. No injuries have been reported.

The recall involves Specialized Fuse Comp and Fatboy SE bicycles with Stout cranks. The bikes come in Gloss Hyper/Black Clean and Satin Gloss Black/Rocket Red for Fuse Comp and Gloss Warm Charcoal/Black/Gallardo Orange and Satin Oak Green/Blac/Rocket Red for Fatboy SE. Only cranks with “STOUT” written on either crankarm and equipped with a direct-mount chainring manufactured in 2017 are affected. Cranks were manufactured in 2017 if the serial code imprinted on the inside of either crankarm starts with “17.”

Consumers are being advised to immediately stop using the recalled bicycles with stout cranks and contact an Authorized Specialized Retailer for instructions on how to receive a free replacement crankarm. The items were sold at specialized retailers nationwide for between $1,400 and $1,500.
