Bikewright Workshop Project 1986 Bridgestone MB-1| Part 1

This is the second post in our series on Bikewright Work Shop Project 1986 Bridgestone MB-1. Check out our previous post at 1986 Bridgestone MB-1 The Starting point


Just like remodeling a house there's demo day! I started my restoration process with disassembly by taking the accessories off such as the water bottle cages, frame pump, and a rear rack. Each item has to be inspected for damage to see if it can be reused as-is or if I can fix it or if a replacement needs to be sourced. 

In this case, the bottle cages are mismatched and will be replaced with stainless steel King Cages
The Zefal HP frame pump has an interesting arc to it. The pump still works after 23 years! I called my friend to ask him did he happen to remember why the pump had an arc in it.  He told me the pump was used as a defensive asset when he was attacked by a dog while riding.  I am going to call the pump as a loss! I am on the fence if I will replace the pump or not. While the Vetta rack looks good overall it has a slight bend in it. All the mounting hardware on the rack is rusted and will either have to be cleaned up or just replaced. Since Vetta no longer makes bicycle racks I am going to try to fix the issues with the rack. The Vetta SL saddle was not the original saddle on this bike and this one is shot! The right seat rail is bent and there was rust on the rails. 


I have no idea what type of chain lube was used on the drive train. But there must be a pound of dirt on the rear derailleur, chain, and crank. But the years of grime comes off really easy. The freewheel is a Shimano MF-Z012 5 speed 14X28  which was a surprise to me. I knew that this was the second freewheel on the bike. I thought for sure it was a Suntour freewheel. I did a little research on the web and found out that I will be able to source these. The Suntour freewheels are a little harder to find. The cable housing for the rear derailleur is a metal spring-like housing. I have never seen this before and this one happens to be damaged. After removing the chain lube the jockey pulleys have seen better days. On to the cranks! The rings on the crank are big... The small ring is a 28 and the large is a 50.

I figure that I was going to have a hard time with the bottom bracket. At first, I could not figure out how to get the bottom bracket out. I was thinking that I would have to make a trip to the LBS and buy a special bottom bracket tool. But then I remembered that a friend gave me two-pin spanners years ago. I guess I am a bit of a packrat. But I was lucky to have the right one and this was the first time that I ever used them.

After getting one of the cones out and the spindle I could see that some water had made its way into the bottom bracket. The grease is a nice light brown. I will totally take the cone apart and degrease and repack it. The spindle must weight a pound!


Just from the couple of posts that I have put up, you can tell that I have a few issues with the bike. None that are show stoppers.

The other night I was reading an article on Grant Peterson, that was originally published in the California Bicyclist and was posted on the adventurecorps.com website. Grant Peterson said " I think parts should be repairable and there should be interchangeability. People should not be encouraged to throw apart and replace it with a whole new one in the name of helping the economy".

I sure hope that I find that is true with this bike!
