I cracked my wheel rim. with picture

You could be right! Good spot, will have a look when I get home.

Just a thought, but do you have rim brakes and are the rims intended for discs?

Can't see how that would cause the crack though. Premature failure of the rim wall maybe, but cracking down the centre of the well?

 

[sarahale]

I have disc brakes anyway

I agree with Tim Hall I would want a wheel to take more punishment than that. I have seen wheels "D" shaped without signs of cracks. There doesn't appear to be damage to the paint and for that size of split I would want to see a huge buckle.

Just wondering about general fragility, but the OP says she's on discs anyway, so I'll shut up now.

Here we go, quickly cleaned with some water. So there is a little rust, I wonder if the crack has been there a little while? Its huge!! Then silver nicks on the rim are most likely where I have used tire levers, apart from those no obvious bumps/knocks. Very strange.

 

[Illaveago]

That is one big split.

I don't have pics as that wheel was chucked away, but I did have similar cracks all over the rear wheel in my B'Twin. It is a two years old bike. There was a bit of rust as well. I've noticed it when I actually felt the wheel being kind of soft and wobbly. Both wheels have been replaced (the front one even prior to that actually, as the original one was stolen) and there is no more problems so far.

So there is a little rust

There was a bit of rust as well

The rims will be aluminium so it won't be rust, aluminium corrodes so you may think it looks like rust, if the rims are steel it could be rust but its a long time since I have seen a steel wheel and wouldn't expect Selcoff or B'Twin to be fitting them.

Um, can anyone see spoke holes? 'Cos I cannot.

That's because it's a tubeless rim, as mentioned up thread.

I am just curious, how do the spokes fit in ?

 

[Old jon]

Ooops!!

Magic I think. Tis the devil's work.

An impact causing deformation. A notch in the valve hole. Brittle rim material. I imagine that all of these factors conspired to cause your rim failure.
