If you put the chain in the small ring up front and the smallest cog in the back the chain rubs against the large chain ring. Is this normal for this frame becasue the chain stays are so short? Is the frame defective? Can this problem be solved by puting in a longer spindle?

it's probably okay. is this a triple chainring? you always want to pick a gearing combo that makes the chain as straight as possible. riding with a gearing combo as you described above will put unnessary stress on the chain and components.

:werd:

You need to come up to your middle ring up front and gear appropriately from there.

what does :werd: mean?

It's one of those things you just have to know about or else it's stupid and pointless. And I have no idea whatsoever how to explain it.

You never want to ride big to big or small to small. That crosses the chain and will cause that rubbing sound. So yes, that is normal. This happens worse with triple chain rings. The best habit to get in is to shift from 39 to 53 when the rear cogs are in the third, fourth, or fifth cog.Since I have gotten into that habit, I have not had that problem anymore.


When you have big to big or small to small, you put strain on the chain and have a higher probability of it breaking on you.

I understand that cross gearing is not a good idea, and I don't ride that way. I found this problem when the bike was up on the rack. My concern is that the chain rubbing on the large ring indicates that there is something wrong with with the alighnment of the frame or the crank set.

B/T/W it a double crank.

oh, so it's like 'word'? just spelled differently and with colons at the beginning and end?

I wouldn't worry about it as that's not a positiion the chain should ever be in. It's just the angles that's all exacerbated by the narrower width of the double.

That's the best take I've got on it

The colons are the way to tag smileys on vb boards. sortof like how creates an embarrased face, you can do things like :frown: to create a frowny face.
