Chainring BCDs
« on: July 23, 2016, 01:01 AM »
I'm getting my knickers in a twist about BCD sizing!! :crybaby:

I'm think that Sugino are 130 and Takagi are 110, but can anyone give me a definitive rundown of the brands that are 110 & 130? Thanks in advance! :daumenhoch:

It's the other way around bud.

110 bcd Bmx specific rings are Sugino,Suntour,SR,
130 bcd bmx specific rings are Shimano,Takagi

Tuf-Neck,Pro Neck,PPP,Addicks & similar dual BCD rings fit both sizes.

I'm sure there's a few that others might chime in on but those are the ones i remember from BITD.Also a few of those companies did other or both BCD sizes but were not BMX specific & meant for road bikes,racers,etc but some were still used for bmx.
