MMA Sports Ltd is recalling all Sunline V1 Carbon Handlebars with 31.8mm center clamp diameter.  Effective immediately, the distributor says the bars pose a risk of cracking or breaking, potentially causing a wreck and/or injury.  They say consumers should stop using them at once and return them to their authorized dealer for a full refund.
No word on whether this applies to consumers outside of the UK, and this appears to be a recall from the distributor, not the manufacturer.  Full info is on MMA Sports’ website.
