Richey cracked rim

[Coiser]

There is a 2cm crack on my rear Richey rim.(Just below the spoke) Survived the Fast One yesterday. Don't know when the rim will finally give in.With 4 racing weekends ahead I would prefer not to take a chance.Looking for a rim to replace.(18 speed)Doesn't need to be a Richey.As long as it is of the same quality. Any one that can help? I stay in Boksburg.

 

Thanks
