I'm trying to look up Shimano FH-5600 8/9/10 speed rear hub dimensions for use in spocalc.xls. Spocalc wants left and right center-to-flange measurements. Shimano's Web site gives the following figures:

Flange Distance: 59.2
Dish: 8.8

I played around with various combinations of dividing by two before and after adding or subtracting 8.8, but I'd prefer to know *exactly* how these different specs relate. Anybody know for sure how to work with Shimano's numbers?

Thanks!

Well, if you're set on using this hub I'd say just buy the hub and throw out whatever shimano says about their hubs and just measure it yourself. This probably isn't very helpful advice, but since Shimano is declining to define what 8.8 means for dish, or 59.2 for flange distance, it could be anything. The logical and best-guest scenario is that both values are in mm. But, considering that spokes ain't cheap do you really want to guess?

I don't know if spocalc has updated values for the 105 but I can give you the values I have from QBP. The following Values are all in milimeters

Non drive-side center to flange 37.0
Drive side center to flange 18.0
Non drive flange diameter 45.0
drive flange diameter 45.0

I hope that helps.

Thanks!

This was for a repair -- chain ate a spoke on Saturday on mile 61 of 86 -- so it's a little trickier to measure the hub on a built-up wheel.

Since center-to-flange distance can't vary too crazily, and since small variations in this dimension don't change spoke length appreciable, I used the previous version of the hub (5500) from spocalc. Turns out I had a spoke of this length here at home, and was able to do the repair today. Yay!
