Need specs on current and recent Altus series hubs...

Hi Folks!

Don't often create my own threads...but then again...I don't know EVERYTHING!!!

I am updating my own Excel based spokechart app, and since the hubs below are very common in today's repair environment - I need to cover them. Problem is, I've only had physical access to one. Furthermore Shimano doesn't post specs for them online.

First column is the Altus hub# number, second column is the hub diameter and the third column is the left (non-drive) and right (drive) offsets. If anyone one here has recorded them, I greatly appreciate it if you can fill in the numbers for me. Values for diameter and offset are center-to-center for diameter and on-center for flanges.

Thanks!






HB-RM40 100MM FRONT

FH-RM30-7 130MM REAR LEFT
FH-RM30-7 130MM REAR RIGHT

FH-RM30-7 135MM REAR LEFT

I'm 99.9% sure that if you use the dimensions from similar Shimano hubs you won't be off by more than a millimeter. Shimano's RM30 and RM40 hubs are about as generic as you can get- I would be surprised if they were different dimensionally from Tiagra or Deore hubs.
