I have a Oryx Equipe 100 with Alivio front derailleur, Deore rear derailleur, aluminum frame, etc.
The problem is that it makes noise, especially when I pedal hard, like on a hill, but eventually the creaking occurs all the time. I brought it in to get it fix...they didn't even try to figure out what was wrong, did a tune up, and charged me for a tune up...that fixed it for about 10minutes!!!
I've tried lubing everything, I've looked for cracks in the frame, I've made sure everything was tight...so did the bike shop. But no matter how many times I get them to tighten stuff on my bike the sound always comes back soon after.
They told me it was likely my bottom bracket, but they tell me its in good shape. Pedals are tight. Brakes don't rub. Chain looks good, is lubed and doesn't rub. It just bugs me to have a noisy $800 bike that has been making noise since less than a year after I bought it.
What noise does it make you ask? Well, it is a creaking noise that feels like it happens about once or twice every revolution of the pedal...but that corresponds to when I am putting peak force on the pedals.
Its really annoying, I'm going to look into adjusting the derailleurs myself, since the bike shop people at the London, ON, Canada Cycle Path seem to be a little incompetent! Sorry.
If anyone has any ideas, or can help me locate the source of the sound it would be great...unfortunately I have to be riding the bike to hear it...and that means I can't see what is going on.
