First the handle bars. They cut them in half and then welded a piece of tubing into the left side. Them slid the right side bar onto the tube. Drilled a bolthole through the right side piece and the tube. Installed a bolt through the hole. Then a two-piece around shim to make it the right size for the headset. It has not failed as of yet. I took them off last week to see if they where bent at all. And they are still true and striate. But I do still think that if any part is going to fail it will be the bars.

To say that if you take a wrench to a bike that it is not a Trek, Denali, Grant, or whatever that it's not a Trek, Denali, Grant, or whatever any longer. So the first time you get a flat and have to remove the wheel to fix it, then it's no longer a whatever (Brand name bike)******************** And have you never adjust the seat or handlebars on a new bike at all.... Or adjust the Break pads********** Then you’re not a commuter or biker.

As far as replacing any parts. I have not yet changed any parts out.

And yes I am fast on any bike. I know most people ride between 10 and 15 mph. However I am not most people.

As you can see from the above video I am fast. My wife was out taking a video of the son on his new bike and I happened to go flying by. I was coming in form a 12-mile ride when She was making the video. My average speed for that ride was 23.6 mph over the 12 miles. I hope this will put to rest the speed issue.

Here is a drawing of the handlebars.
