Hey. So I somehow managed to break off the left arm of my Gates CDN S150 crankset. Thought it won't be a biggie to find a spare, but it seems that no one sells them separately and it's quite hard to find a decent substitute. The arm itself is 170mm and has no curve to it, so completely flat when laid flat. Almost all spares I can find on ebay have some sort of profile which is probably not ideal? I know it's not the most popular drivetrain in the world, but maybe someone has dealt with this or just has a suggestion? I found a few that are mostly flat, among them is a Compagnolo one that looks alright, but then read that it might not fit properly.
I'm looking at these:
Apparently Gates is using J.I.S. type BBs.
Given that one arm snapped I would
Let Gates know
Replace the drive side with something less prone to catastrophic failure
Hah. Letting them know might be a good idea. Not sure if there's anything better to replace it with though, maybe only CDX.
It’s just a square taper crank. Probably 130bcd.
Replace it with anything you like.
Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.
