After testing our latest advanced prototypes of the Vector system, we are still not satisfied with the results. As you can imagine, Vector is a complex, precision measurement instrument and as of yet, we are unable to ensure that this device will meet the expectations of the cycling community. Presently, we cannot estimate a delivery date but we do not expect the product to be ready in the summer of 2012, as previously targeted. We understand that this is a highly anticipated product within the cycling community, but Garmin’s commitment to quality necessitates this additional delay. We will update our customers when we have additional information to share. Thank you for your understanding.
