    50T Chainring

    I just picked up some Omniums with a 50T chainring. The seller stated that it was "true track" but i'm curious what effect will a 50T have over what I've come to believe is a standard 48T chainring. Apparently the chainring is a vintage Sugino Mighty (somehow different then the current version, or so the seller stated). Would it be best to leave it on or switch it to a 48T? The seller was very animate about this chainring being worth a lot, NJS ect but i'm just interested in the difference of a 48T v 50T. About to purchase a cog but wanted to see what the more veteran forum members had to say.

    I don't understand what you're concerned about. For a given cog the 50 will give a slightly higher gearing than a 48

    It looks cool so keep it

    Why would a chainring affect the chain line? Any effect due to thickness differences will be negligible.

    I suppose I was just curious on the effect of a 50T vs 48T would have and why most builds I see have 48T.

    Most crank sets I've seen come stock with 48t chainrings. Maybe it's just a manufacturer preference?

    Changing the chainring size shouldn't change the chain line. It'll just change where your rear axle sits in the rear track end.

    smaller than 52, larger than 42. It's a size that lets you get through the range of high to moderately low gears with cog sizes shops usually stock, that's my guess.

    It's a Sugino "Drillium" chainring. It has "S-50" stamped on it with no other markings, right?

    It's a nice chainring. Keep it. If you choose to ride it, use a cog that is 1 tooth bigger than normal. If you usually run a 48/18, now run a 50/19. It will take up more chain, so consider that, too. A longer chain than is currently on your bike may be required.

    THIS was what I was trying to get at with my question regarding the chainline ect but was unable to articulate it.

    I have an unused 48t Omnium chainring that I'd be willing to sell. Shoot me a PM if you want it.

    What's wrong with a 50t chainring? I run a 49t and want to go up.

    This. You'd notice much more difference dropping a tooth on your cog.

    From all the sarcastic comments, looks like you should be ok ... ( going to a 50, its maybe 3-4 GI more. )
