Would this this chainring....

be suitable for fixed gear? Im trying to build one but I'm struggling with the chainring. I have sugino cranks ( i think there RD's, cant be 100% sure as half the lettering has rubbed away)

any help / advice would be appreciated.

probably not unless your crank is 110 BCD, which it won't be if it's RD.

You need to match the BCD for the chainring and the crank. It's a measurement.

The RD measures 130bcd, which is probably the most standard.

Try DH Cyclesport, they usually have 130 bcd sugino chainrings for around £15 and usually advertise on ebay

Alloy BMX race cranks which sugino made plenty of all use 110bcd rings as standard.
