Hey guys, I got a sugino 75 crankset that's 167.2 mm install on my bike and I also have just the driver side sugino 75 grand mighty that's the same length. Do you think I can just replace one side and I can still ride without any problems or will this do damage to my bb?

thanks

what's wrong with a matching crankset?

Well, if he doesn't have to buy a new arm then it saves him money.

EDIT: I may have misinterpreted the situation. If you have a complete set, I would use that. I don't see why you need a grand mighty on one side.

it won't damage anything if they're both the same size but why do you want to do this?

if something is wrong with the drive side 75 then you should be able to use the grand mighty without trouble (i think). it certainly won't f up your bottom bracket, you just have to worry about your Q factor being off (the distance the crank puts your pedal from the centerline). if nothing is wrong with your 75 crankset and you just want to have a "grand mighty crank" on your bike, then just ride the matching set. no one is going to **** on you for 75's

The only difference between a standard 75 and a 75 Grand Mighty is the finish. The Grand Mighty is purdier. Moar hipster pointz.

yeah... there isn't any hipster points for running half a grand mighty on your bike. If anything, it's more of a reason for a thief to nab it.

wait till you come across a non-drive side arm and then run the set.

Just spray paint both arms so they match. Problem solved.

Nah. Then it would just look like an Omnomnom.

they're not the same. the grand mighty has a whole different manufacturing process. the cranks are held up to higher standards.

A Mercedes may be a better car than a Kia too, but having half of one doesn't make you a ******.

It won't damage anything even if they're not the same size. But yes, why?

Yea i picked up a driver only....i just figure it's more durable or what not.. the finish on it seems to be better than my regular 75's. Thanks guys.. I might just hold off on it.. hopefully an arm will come up..

The only thing its going to do is give you a janky looking mismatched crankset. Its not more durable, or stronger, or stiffer in any significant way than your 75s.

I'd just run the 75 crankset and Ebay the G.M. arm. Or just buy the other arm, fortunately you already have the more expensive drive side.
And there is nothing wrong with running a regular 75 crankset, that's cool enough (if that's what you're after).
But just like deciding when you're gonna take a ****, this decision is up to you.

Wrong. It's up to me.

henryselling - go take a ****.

I'm confused with your last line..??? so its not a good idea? or doesn't matter? Sorry..

... he's saying these are all options, but you should make your own decisions, instead of just taking any random advice from the internet.
