5 milimeters

Such tiny changes make so much difference.

Handlebar height from axle is now only 1.5 cm lower on the white bike, so we will see if it works for my back.

I shuffled parts because the black bike would not take 180mm cranks without frame impacts. My old cranks are 175mm and the 5mm difference, or 10mm total in a circle, is huge.

My seat is set back 25mm and I am not sure if I will undo that yet, but the nose is uncomfy.

Thought I would need a short test but I will need 100-200 miles to see if 180mm is a good move.

Also, the non-shimano bottom bracket I pulled is so much better for square taper, but I really like the new hollow axle BB. I have an SRAM/Truativ GXP, which is very similar to Shimano Hollowtech. The wider bearing position is nice. Less flex.
