Bust Crank Spindle, Warranty?

[Frail. "Will forever remain "Frail"]

Whilst I was out Cycling last week, I bust my SHIMANO Crank.

How does one Brake a CRANK?

Can I claim for a Warranty, it' been Barely Used.

Please give me your thoughts, Thanks.

Krag, waar is jou einde.

With the condition that crank is in....

How old is the BB?

There must have been a manufacturing flaw from the start, I cant see any other way.

BB is 2y old max.

How much have I ridden over the 2y, four times.

Then how on earth can it be in such a sad state?  Or is it only dirt I see?

I was also wondering... Maybe the cranks are second hand?

Who is the manufacturer and what does their website state is the warranty? 

It doesn't matter if you used it once inside of the warranty period. It is based on time and not number of uses. 

I would imagine titanium parts to have at least a 5 year warranty. Speak to the shop you bought it from. 

And wash your bike

Dirt, sand and Rain.

Looks like you broke the crank axle, not the BB. The BB is the part that's in the frame. Are your BB bearings still spinning smoothly?

Could you send a photo of the other side of the crank, I'd like to see what make/type it is?

Just out of curiosity, what brand are the cranks?

Never.

I was present when the Mechanic fitted the BB.

Ok, I was just wondering. Also the crank spindle is what snapped, not the BB

Ok. Next time it's been Raining I will Stop roadside and IMMEDIATELY clean the bike Down?

SATURDAY, it Rained constantly.

SUNDAY, on / off.

I continued Cycling

Um, I aint no metallugy person, but judging by the dirt on the crank I'd hazard a guess that the bearing itself ceased up, and with the rotation forces on the crank arm/spindle at a most inoppurtune moment... it simply snapped. 

Heck,not even tallboy 3's are made from this stuff so failures can and do happen

this is not a tdv6 disco 3/4 problem. I doubt a crank will just snap from a bearing that ran hot.
