Can anyone tell me what it would be on a sugino 44 t
110?

I am pretty sure all Sugino is 110 BCD

All of them except the 130 BCD ones

Just measure it to be sure, it is dead easy to find out the BCD...

pretty good that sean - or

sheldon says - Measuring BCD: This 110 mm BCD ring measures 64.7 mm center-to-center.

Multiplying this dimension by 1.7 will give you the actual BCD for a 5 bolt chainring.

Use 1.4 for 4 bolt chainrings

Aren't Sugino rings both?

Jaan · « **Reply #7 on:** April 18, 2014, 08:24 AM »

No, typically they're 110
