I bought a Windsor Wellington 3.0 online, and let someone I trust handle the semi-assembly. Long story short, he cross-threaded the pedals with the cranks, and the pedals stripped out the cranks completely. There are literally no threads left. Is this an expensive fix? I understand improbably need new cranks, but where do I go to replace them cheaply? Specs for the bike are here: http://www.bikesdirect.com/products/windsor/wellington3_IX.htm Thanks in advance for the help. The bike is 4 days old!
