Assuming the same fork rake and same HTA, fork offset and trail. How much do you think a change of 1.5cm will make. I am on the fence between a 58 and 61 CX bike. My current has the wrong geometry for me (73* HTA and 1018 WB, didn't like the front end handling), and I was first drawn to the 58 (72.3HTA), but would also fit on the 61. Same setup, just a bit different setup with the spacers under the stem.

My brain looks at a 1043 WB and thinks it looks so long, (the 58 is 1028). Am I making a mountain out of a molehill?
