I live in WA state and do RAGBRAI every other year, so rather than having to ship my bike back and forth decided to buy a second bike and have it sent to Iowa. It was listed as 51 cm, but if it is I must have grown a few inches on my plane ride here. I measured it to be 49 cm. Can't believe how much difference 2 cm makes. Realize not too many will care, but wanted to gripe a bit. Very annoyed!
