First off i would like to excuse my noobness, but i'm just trying to understand my bike/bike theory a little better.

I know that for chainlines they should be as "straight" as possible correct? ON a frameset with a 110mm spaced rear (112mm to be exact) will newer cranksets such as DA 7710 or 7700 be more geared (no pun intended) for the 120mm spacing? i guess what i'm asking is if the chainline will be pulled even more towards the flange?

followup question (i know it's been covered as i've search "110mm rear spacing"), but i see that the US market for 110mm spaced axles and hubs are in short supply or in "no" supply at all. Phil Woods makes 110mm hubs, but are there any other options which are not 30 years old and are available stateside?


Thanks,

Increasing hub spacing generally means adding the same size washer to both sides of the hub (and vice versa for decreasing spacing), and therefore it has no effect on chainline. Of course you can add more washers to one side or the other; people do this to fine tune their chainline. You then have to redish the rim so that it still sits right on the mid line of the bike.

Yup, chainline should always be about 42 (though it keeps creeping outward the more companies are out there making cogs) regardless of rear spacing. What frame do you have that's 110? 110 stuff is out there, but yeah, nothing new and cheap is 110. Some hacks are possible.

a nagasawa frame =\, so yea...apparently it's 112mm :errk:

At least it's pretty.

at this rate i can use it as a paper weight =\

I bet in some fancy smanchy corporate office, there is a more expensive paperweight.

Just to make sure Mander's point is clear, the rear spacing has no effect on chainline. It might be a pain to find a hub that fits, but you can use any crankset on the market.

Wait, maybe I'm misunderstanding your question but just in case: if you've got 110 rear hub width, and it is steel, you can cold-set it to 120 no problem. Many shops can. Check out rear hub width or cold set on sheldon brown. I just had it done on a conversion.

edit--crud, I meant "if you've got a 110 rear drop out width...

PMed, but i'll ask the question here too..

does cold setting cause the frame strength to degrade or lessen?

Some steel can be cold set, some is too hard/brittle/whatever. I don't know enough about Nagas to say more, but if there's a tubing sticker or someone who can say, "you idiot, all Nagas are ___" we can see. I also PM'ed you about hack 110 hubs.
