Dear members,
I need your help in order to understand something. I have a 2007 Specialized Globe Sport. I bought it second handed and it was almost new when it came to my hands, about 6 months ago.
It came with Alexrims wheels and since I bought my first 700x23 tires, and the back wheel keeps untruing even though I had them trued @ the bike shop for more than 3 times for the last 4 months. Thinking that 700x23 tires because of the high pressure they require were the responsible for the untruing of the wheels, I put my 700x35 wheels back.
Now I am using some excellent, puncture free, Schwalbe Marathon 700x28 that require a bit more pressure than the previous 700x35 ones. And today i sensed something strange on my ride. I went to check and a part of the rim was rubbing my break pad again.
Is this a problem of mine or the rims? Maybe I ride from some sidewalks to roads and vice-versa and the wheel suffers some additional impact. I don't know. Can you help me?
Thanks a lot.
Pedro
