Well this morning Sue returned me to the bike shop at 11am. The wheel was delivered at 2.30pm. Unfortunately a 24 inch wheel was sent rather than the required 20 inch. However, we removed the internals of the old hub and replaced them with the new, which by far was the best solution. So was on the road at approximately 3.45pm. Thanks to the guys at Finish Line Pro Bike Shop in El Centro.
Cycled below sea level today.
