Hello and Welcome,
I am not a huge fan of Walmart. Or at least I like to think I am not.
But after hearing from a friend that they had seen exercise bikes on display there. I thought to myself, what can it hurt to look? Well after not being able to find an exercise bike that I wanted, I decided to wander over to the bicycles... Just to get a look at the latest in Department Store bicycle offerings. I had no intentions of making a purchase. Then I spotted the last thing I ever expected to see, a single speed bike with a flip-flop hub. However the brakes looked really cheap as did the crank, seat-post, pedals, handlebars and grips. But the frame looked like it could get the job done. And the wheel-set looked entry-level. But they did spin fairly straight, well the rear one did anyway. I`m thinking, this could possibly work with a few improvements. Then I saw the price tag $99.00!!
lugged frame fixed gear bike? How much will it cost me to make this thing reliable? Then I came up with the perfect excuse. It was as if the Devil himself were whispering in my ear. "You can make this a really cool bike for under 200.00 Then you can blog about it!" Well There you have it, that is how I came to purchase this department store fixed gear bike. I am reminded of a line from the movie Tombstone when Doc Holiday said "That's what I love about Wyatt. He can talk himself into anything."
1/8 bicycle chain. The rear rim is yellow with a red tire and the front red with a yellow tire. I would have preferred they both be the same. I decided to switch the tires so they match the rims. My hope was it would give it a taller look, and to a degree I think it did just that.
side pull caliper brake. ˈCHēzē Adjective: cheap, unpleasant, or blatantly inauthentic. Yeah! that is the word I was looking for alright. I have some vintage alloy (side-pull) caliper and center-pull brakes in the shop. I think I can polish-up something that will get the job done and look good doing it. I will not be installing a rear brake. And the resin pedals are going to be replaced with Avenir ultralight pedals with old style clips and straps. I can just see me trying to perfect my skid with my feet sliding off the plastic pedals. Did you ever notice how many other names they have for plastic?
cork handlebar tape. Which I now need since I have decided to make a set of flop and chop bars for the fixie. So I should be right on target when finished.
threaded headset were both set too tight. But what really bothered me was some of the bicycle grease. It looked like it had been scraped-up off a dirty floor. And there were little pieces of dirt or scrap from the manufacturing process. It appeared that nothing was cleaned-out before greasing.
You have seen me do enough bottom brackets and headsets on here for a while. So let`s start with the front wheel axle (ABOVE) with the free bearings. The first thing I need to do is break this over tightened axle loose.
Above: Here I am loosening the front axle using two adjustable wrenches. Once the cone nut breaks loose only one side is going to be removed easily. But that is no problem. We only need one side to be loose to grease both sides. I will hold the bottom nut (tight side)so the axle does not spin as I and loosen the top side (by hand) to expose the bearings for greasing.
Above: Here after greasing the bearings I am replacing the cone/nut by hand,leaving the lock-nut off for now.
Once I screw the cone into place (snug not tight) I just wipe-off the excess grease with a paper towel.
Above: Now I have flipped the wheel over and loosened (unscrewed) the top side which is now backed-off enough for me to wipe-clean and re-grease the bearings. I am careful not to back it off so far that the opposite side cone comes off the threaded axle. With a finger on the end of the axle, I can feel when I have backed the top side out to the max. I just stop when the bottom end is flush with the axle cone-nut.
Above: Once I have wiped and re-greased the bearings I can now screw it back down into place. As always not too tight (no play no grind) Afterwards I can flip the wheel over again and replace the (thin) lock nut on the opposite side. When replacing the lock-nut I can use a cone wrench to hold the adjustment on the cone while tightening the lock nut. I suspect this is where the factory screws up and the axles end up being set way too tight. Give it a spin when finished holding the axle at each end. If it feels too tight or too loose try again. Remember "No Grind and No Play" is what your looking for. Now I am ready to move on to the rear wheel bearings.
Hozan Bicycle Bottom Bracket Tool. The lock-ring is reverse threaded. So turn it clock wise to loosen it.
Avenir Chain-Whip crank it counter-clockwise to remove it.
single cog freewheel removal tool. So I will take it apart and remove it in pieces. If I do use a freewheel unit on the bike it will be a freewheel with slots for a removal tool. I`ll save these parts but I doubt I will ever use them.
fixed gear cog is working fine. I have temporally re-installed the original crank for testing. The new crank and post should arrive in a few days. I had already ordered grips before I decided to change the handlebars. I will be wrapping the new bars. But I`m sure I will use the grips on a future project.
hacksaw for a sec to take this pic.
bullhorn pursuit style handlebars. And once they are all taped-up I think they will look pretty good too. I think I will mount this front brake lever differently so I can compare the two.(this one to the Schwinn fixie)
metal file these off right away. Not only can these sharp edges cut you, they can also cut into your handlebar tape.
My parts order has not arrived yet, So I`m going to close for now. I will get back to work on the Fixie as soon as the parts are delivered. Look for the "Thrasher Fixie Finished" post within a week. Until Next Time, Please Ride Safe and Remember to Always RESCUE, RESTORE & RECYCLE Cheers, Hugh
