At least it is not may
with winter coming i thought now would be a good time to do a few things on my 2011 xc 250. found out my linkage is a bit more than cracked. I was a bit sad at first but i know i will get it fixed for free so that's good.
Just thought I should ask what could cause this? Liam Last edited by liamthom; 11-27-2014 at 11:44 PM. Reason: It's not ex, it's xc. silly me |

that's what i was thinking, also with the rust make me believe that it was broken for a some time

Looks like maybe the suspension bottomed really hard (maybe more than once). I have been seeing several broken frame threads showing up here. Kind of makes me wonder?

I have a 2011, witch was the first year with the new style of frame used on the new bikes. so after a few competitions they would have found the issues

Not necessarily. You see I spent three years in college studying metals and welding and then ten years welding and fabricating. What these frames could be experiencing is metal fatigue. If the steel used is of a lower grade or if the frames aren't gusseted and designed to distribute loads properly the stress points could weaken over time. It could happen right away or it could take ten years for problems to show. Also race teams that abuse the bikes the most only use a bike for one season and then it is passed on. So they most likely aren't going to discover these problems and the slower riders don't ride hard enough to ever discover the issue or it takes 4 or 5 years for it to show.

The' 11s were the last year with the old linkage. Yours isn't the first to break in that area, and the factory used to sell upgraded aluminum hangers as well.
Most race teams replace frames on a regular basis.
