Ellen Ripleywrote a question about Ridley Noah Road Bike Frameset - 2017 on August 6, 2018
If I'm an XS on the Helium, it might stand to reason that I would be an XS in Noah as well. However, effective top tube on Noah is a little over a cm shorter than Helium. I'm already running a 140 stem on my helium. I'm 1.71 meters (5'7") tall with a short torso. 32.5 inch inseam. Thanks!
