I purchased their Spin bike Sept. 2013. The tension bolt to the braking system is not holding. I find they do not carry parts for this & don't know where I can get replacements. I put a nut on the end of the bolt, with a wrench taped on the nut to the frame to provide tension to the brake adjustment. What a Mickey Mouse system. This bike is only 2 1/2 years old & the parts are discontinued. Never again!
