heyy guys, My friend just gave me a set of old richey girder rims. There are some spots with missing chunks of metal. So my question is how bad can they be damaged?










Let me know.

It sounds to me like they could be damaged much more. A BFH, a chopsaw, or even one of those aluminum shredders would do the job nicely.

well, I am trying to find out if I can still use it even if it is damaged?

Never use damaged rims if there is metal missing.

sounds like a wheel ready to collapse... you'll hurt yourself!

well my friend being stupid took a dremel tool and just slightly grinded it down...so yeah i think I might still get a new wheel.

Does your friend ride trials by chance? Grinding a rim is not that uncommon of a practice in the trials world. Putting a grind on gives alot more grip for rim brakes. Rims can take alot more than most people think they are capable of, the same is true for your bike.

Just to make a point about rim strength, how many of you (that aren't into trials) would ever think that something like this is normal to do to your rims?

that is quite interesting thanks for the info. No he doesn't do anything like that I don't think...maybe he does I really don't know. I have talked with a few other friends and they say they do it all the time so i think I might just use it on my bike...Thanks again for the info

Hope your health insurance is paid up.
