I have a Leader 722ts with a Sugino 103mm bb, Sugino RD2 cranks, and 44t Messenger chainring.

I haven't put on my chain yet, as it will be arriving in the mail on Tuesday, but the alignment/chainline seems quite off. I don't really want to buy a new bb, chainring, or cranks.

And suggestions on the spacing issue? I was thinking about moving the chainring onto the inner part of the crank spider, as it is on the outside part as of now.

Thanks!

You shouldn't have an issue, and if you do, its probably an issue with your back wheel.

Wait until you get a chain to decide you have chainline issues...

Quick response!

Just wondering, if there IS a problem with my rear wheel, what should I do?

The only reason I said it was your rear wheel is because everything up front is appropriate, correct bottom bracket.

If the line is only off a few millimeters you don't have to do anything. And if its off enough to cause problems, you may have to mount your chainring on the opposite side. And if it is still off enough to cause problems, your wheel was built by someone who shouldn't build wheels.

I still HIGHLY doubt you have problems, and you're jumping the gun. Wait until you throw a chain on there to decide.

Thanks. I guess I worry too much! I was hoping for a perfect chainline, that's all. I'll measure it soon, then go to Sheldon Brown's chainline page.

What would be enough to "cause problems"? EDIT: and what would be the problem with this?

If it's WAY off you can drop your chain. If it's more than a few mm's off, it can cause abnormal wear on the cog and chain. If it's less than that, you're fine.

You'll be fine.

Thanks for all the help! I measured, the front chainline is 45mm, is the same as the Sugino specs. 3mm difference. I'll be riding by Tuesday! (I'll make sure to post a picture of the bike on BF)

i had the same paranoia, i had everything set up and was waiting on my chain, eyeballing it from the rear it seemed miles off

but after i put the chain on and tensioned it it was only off by like ~3mm and everything is gravy

Well, I usually just browse this forum for entertainment but I run RD2 so I decided to post. The chainline is likely to be a little off. It drove me nuts at first and searching forums, including this one, revealed most everyone with RD2 experiences the same. I've mounted the chainring on the inside and outside (it's actually a double) and found it to be visually off either a little to the inside or outside respectively. I built my rear wheel myself and I've double and triple checked the dish. My frame is a langster, I have the 103bb, surly hubs, and surly cog so, had the crankset actually been singlespeed specific, everything should've been on the up and up. In the end I decided to mount the chainring on the outside cause I think it looks better there. With 3/32 cog, 3/32 chainring, and a 1/8 chain I've found the setup to be fairly quiet and I've never dropped the chain. Now that I've been riding it for a while I don't care about the chainline. Usually us nitpickers are the only ones who care about this stuff anyway.

As others have stated, your setup will run fine. If it's a little off, so be it, you'll most likely be the only one who notices or cares. Enjoy!

You would cringe at the chain lines on my bike. The one is probably close to a centimeter off, and no I've never dropped a chain.
