Wow, strange that it would break that way. But if there enough breaks as such and they are documented and acknowledged as legitimate breaks then a recall of some kind needs to happen before someone gets hurt.

Holy smokes, tell Lars to get his steer tube cut or else his bike will end up in the freaks thread. :wink:

Around 1-2 months ago he won a race in Italy with a very difficult route; I think he might be more of a pure sprinter.

It's cx though, it's the unpreaux vibe of MTB, but with Di2 and colnago everywhere.

Personally don't like being as low or stretched out on my CX bike. It's more about bike handling and less about being aero.

Why is it strange that they break?

Hm.. I'm just assuming most of these breakages are due to pre-existing hairline cracks, either from impact or perhaps the rare occurrence of manufacturing defect, and then these hairline fractures multiply and expand over time and through usage. Don't we see similar fractures happen with almost all cranksets?

Also, there are many many thousands of these cranksets out there. Surely many have cracked and many will crack without that justifying a recall.

Cranks having similar fractures with almost all crank sets?

A small scratch is one thing a fracture is a whole other ball game.
Uh that would a big negative from that crank manufacturer.

Nope, not what I have experienced. Especially not cranks of this high end. You don't see this happening to Hollowgram cranks.

A bunch of the same arms fracturing in unrelated instances over and over would (to me) indicate a problem with design or manufacturing that puts some kind of discontinuity, either material or geometry, at that point.

How many 100,000 of 7800 cranks were sold, how many do you know of breaking? I've seen 4 since 2004.

It happens. Especially when (as mentioned) you have the amount of 7800 arms in the world that Shimano would.

Choices seem pretty lame to me! Probably just a marketing ploy anyway; I'm not advocating giving them your info...
