I bought this bike in Nov 2013 and started working on it the following day and yesterday (June 20, 2014) it took the road for the first time in style. A few months ago I thanked the forum for it's wealth of information and patience when it comes to entertaining the redundant questions of a newbie member. I will be here for a long time and will attempt to return my knowledge and experience.
- I will edit this first post with the story of my bike -
