Cracked back wheel

[Simon_m]

Hi there, I'm just wondering how safe these cracks are? I've done some searching already online and I seem to get different results.

Back wheel, aluminum fulcrum racing 5 wheel, road bike which is 4-5yrs old, wheel has done over 10,000miles I would say. Wheel is for commuting. I weight 84kg. There are maybe 4-5 of these cracks around the wheel.

I have not taken my own pics, but the cracks are very similar to these ones:

No.

No don't do it.

 

[dan_bo]

Honestly.

Wtf!

10000 miles aint bad mind.

Rim's knackered beyond repair. Use it as a Hoola Hoop but don't continue to ride it.

Similar cracks appeared on the back wheel of my Trek bike shortly after I bought it (new). The bike has since done 12,000 miles and the cracks have got no worse. I also weigh 84Kg on a good day.
It doesn't look good, but I can't see the cracks when cycling and just forget about them.

lol at Snorri, yes out of sight out of mind. You see the dilemma though. Some say yes, some say no. I could just use it as a winter turbo-trainer wheel, but would like to squeeze as much out of them as possible. Although, dont want to hit a hole and the wheel collapse under me

l. Although, dont want to hit a hole and the wheel collapse under me

Change them.

Do you really want to risk it?

Given its the rear its not quite as urgent but its still a right of IMHO, besides 10,000miles wasn't bad for a commuting wheel.

Had a tour and lots of training rides included in that. I have some new wheels, so I guess better safe then sorry? Cheers guys. Safe riding

With cracks like that, it is time for a new rim.

Had this happen to me once:

oooo that is bad

Change the wheel pronto. It's a critical safety issue and you don't want it disintegrating on a fast descent.
