OKAY, so it really didn't take me all day, more like about 6 hours. But most of that time was sorting through stuff and laying it out to see what was going to work. Then, when I decided to clean and re-grease the hubs.....and dropping everything out of the rear hub. I spent about an hour trying to find where all the pieces bounced when they hit the floor. Also having a 14 year old daughter to shuffle around to the mall took time. The 6 hour bike just didn't sound right. I think I might do another one this weekend! John.
