I have a Mukluk 3 which came with chain/tire clearance issues due to the crankset choice made by Salsa. It is tight with the 3.7 endomorph tire. This summer I will be getting a nate 3.8 tire which will not work even with dishing the wheel a mm or two. I am looking at upgrading the crankset to get the clearance.

I was looking at getting the Mr. Whirly Offset Double but heard that with time and a lot of use the chainrings "explode." I am not sure if that is the case.

Has anyone had an issue with the Mr. Whirly Offset Double?
