Catherine, you might find Velocity to be very helpful. We're going through a replacement process for a couple of well-built Velocity Dyads that prematurely showed stress marks and a couple of fractures similar to yours. They were very lightly ridden (in terms of mileage, weight/load, type of riding, and riding surfaces) on a Wilbury. After seeing photos, Velocity volunteered to replace them — and cautioned against riding them. They were sympathetic about the whole situation and accommodating. Good luck with it.
