Hey, thanks for checking!
BTW, from Breezer's page for the Uptown 8, they reference measurement "B" in the table:
[TABLE="class: geomtable, width: 1"]
[TR="bgcolor: transparent"]
[TD="width: 200"]Size[/TD]
[TD="width: 40, bgcolor: transparent"][/TD]
[TD="width: 40, bgcolor: transparent"]S (17.5")[/TD]
[TD="width: 40, bgcolor: transparent"]M (19.5")[/TD]
[TD="width: 40, bgcolor: transparent"]L (21.5")[/TD]
[TD="width: 40, bgcolor: transparent"]XL (23.5")[/TD]
[/TR]
[TR="bgcolor: transparent"]
[TD="width: 200"]Top Tube - Effective[/TD]
[TD="width: 40, bgcolor: transparent"]
B[/TD]
[TD="width: 40, bgcolor: transparent"]575[/TD]
[TD="width: 40, bgcolor: transparent"]595[/TD]
[TD="width: 40, bgcolor: transparent"]615[/TD]
[TD="width: 40, bgcolor: transparent"]635[/TD]
[/TR]
[/TABLE]
Weird. And they say weights are too non-standard to report!
