I’m building up a bike with a Shimano 2x drivetrain. This is my first time building with shimano at all.
I’ve relied on Sram’s excellent Frame Fit Spec, which seems to have been written with framebuilders in mind. (This one: https://www.sram.com/globalassets/document-hierarchy/frame-fit-specifications/road/2023-road-frame-fit-specifications-rev-c.pdf)
I’m looking for something similar for shimano components, but I haven’t had any luck finding one.
I’m especially looking for a chart like this:
Do any of you have a link to a doc from Shimano like this?
Thanks!
Justin
I found an old post on r/framebuilding with this link in it: https://cdn.shopify.com/s/files/1/0336/9713/files/Shimano_2018-2019_Tech_part_1.pdf
It’s pretty out of date, but luckily it has the info I was looking for on page 70.
Since I couldn’t find any other links to this info on customframeforum, I thought I’d post it here for posterity.

Thank you! I was looking for this as well.
From the latest manual ie. 2023

If you have an account with Shimano your rep should be able to provide the latest manual or at least the pages you need. For some reason Shimano has become stingy with this info.
