pedaling too fast? causes...
 

When I pedal too fast, I hear a clunk and my footing on the pedals make my feet slip. Has anyone experience that? Can I get any tips on how to prevent this from happening?

Change gears...

or stop pedaling

or lube your bottom bracket

its brand new got it 2 hours ago, i don't think i would have to lube anything at the moment.

what bike?

its a 2008 specialized rockhopper.

Get clipless. That will solve the footing problem.

+1. I went clipless and im deff not looking back, unless i start freeriding.

I don't think its that. It has something to do with the gearing. I think i'm stressing the chain or something.

I guess I don't understand the issue you are having.

Stop cross chaining and properly shift the bike.

Consult your mortician.

what do you mean by cross chaining? does it mean, if i put it on the high gear and then a low gear at the wheels?

so the right way is have the high gear with another high gear?

Crosschaining is running the largest rings together or smallest rings together so that the chain crosses from one side to the other between the cranks and the cassette. It sounds like the chain is jumping under load. Did you get the bike at a shop? If so take it back and have them take a look at it. They'll be able to tell you a lot more by looking at it than we can over the internet.

thanks, but yeah, thats what i have been doing. I guess when you set the 1 2 or 3 gear, you have to have it in a specific gear in the rear huh? i'll learn that stuff myself today. thanks a lot for the explaination streetlight!

I may get jumped on for bad advice :rolleyes: but my understanding is that if you are in your granny gear up front you'd want to be using about the 5 largest cogs in the back, in your second ring (assuming a triple) you should be able to use all 8 or 9, and in your largest front ring use the ~5 smallest rear rings. The point is to not have a chainline that is farther off than the derailleur can handle.
