Ok, so I installed these Brake Pads for the back brakes of my bike: http://www.amazon.com/Avenir-Sticky-...rake+pads+bike

They worked very well and were extremely powerful. After about 5 minuets of use on a bike trail, the brake cable broke due to the strength of these breaks. Were they the right ones? What cable and brakes can I replace it with? Can I buy these on Amazon?

On a separate note, I cannot fit my Camelbak water bottle in the bottle holder on my bike. Anyone have any experience with a water botte holder that can fit this model?

Thanks for all your help!
