With a couple mountain bike races coming up that I want to race in, Truman's Big Love, SS March 2 Spoke Pony Showdown 3hr/6hr March 15th I guess it’s a good idea that get a bike together. And I mean together. I used to have a couple 29r’s (Titus Racer-X 29, & Surly Karate Monkey)

This was my Titus Ti-Racer-X, I had it Custom made.



I’m going to build a 29r frame with a twist. They will internal 3-speed hub specific . . . "Just say NO to Chain Slap" . . . a problem with 29’r is the down-tube/ fork crown clearance. To remedy this I’m going to borrow an idea from an old BMX bike the GJS-A Frame.

Only with a slight modification by using two ½" tubes going from the head tube to the down tube instead of one like the GJS has. Either way this will give clearance for a suspension fork’s fork crown. Be it a Pop-Loc, or whatever the case may be.

I’m going to build this frame from straight gauge 4130 from airparts, aircraft supply. Sure it’s not the lightest tubing, but for my first few frames I’ll have nothing to lose but a few bucks. I am going to order in the bottom bracket shell, dropouts, cable stops, and guide. Maybe when I get a lathe I’ll make my own bottom bracket shell, but it’s far easier and cheaper in the long run to just buy them. Some people do make their own dropouts, I still might, but I’ll probably just couple that with the purchase of my small parts.

The specs for the front triangle look like this.

Down tube: 1-1/4"

Tope Tube: 1-1/8"

Bottom Bracket: 68mm (Remember its 3 speed specific, so I have 120mm rear spacing)

Head Tube: 1-3/8" and 1-1/2"
This is a tough one. For 1" it’s simple. 1-1/4" give an ideal I.D. of 29.9mm for a 1" headset since the bore needs to be 30.1. Plus the DIA matches well with the down tube.

For 1-1/8" is a bit harder. The key is getting a bore of 33.9mm. The next size tube up from 1-1/4" is 1-3/8"O.D., or 34.9mm O.D. at .035 thickness. Boring this to 33.9 will leave .5mm wall thickness, not thick enough and going to the next size up 1-1/2" to get the correct bore will require getting a tube thickness of .095, or 2.41mm. At 1.4Lbs.per foot that a heavy pipe.

My solution is to use the 1-3/8"x.035" and make reinforcement rings out off 1-1/2" x .058" tubing for the top and bottom of the head-tube. The I.D. of 1-1/2" x .058" is 35.15mm, and the O.D. of the 1-3/8"x.035" is 34.9mm. Leaving .125mm of gap. Fill with braze and go.

Since I’m building a fork with 450mm axel to crown this idea is more of an experiment than applicable. (The details of my fork design I’ll discuss later, but basically I want to get my bars 2"-3" below my seat.)

Seat Tube: 1-1/8" (at .035"/9mm wall makes it compatible for a 26.8 post), and 5/8" tubing
Another idea I’m going to employ is the idea of the split seat tube. I want to give my bike 16-1/2" chain stays. The problem is if I use a conventional full length tube, the back tire will hit the seat-tube. This will give the tire clearance, and to some point the tire will actually track between the tubes with a WTB 2.3. Exi-Wolf. Will it survive out of the saddle crank mashing? I guess I’ll find out.

I'm you look at my post from yesterday, click on the picture to see what I have in the works. Right now it looks like this.

Well there you have it. I'm thinking something got lost in translation. I wish I could come up with something clever to say . . . I'm pretty tired from working out the details of my next frame . . . I'm not sure I could come with something if I was fresh. I mean where do you start? . . . . the scuba suits? . . . the glasses? . . . The foot in the crotch?




Well anyway heres my plan for my next frame. I'll post the details about the design tommorow. Until then here it is. I'll leave you thinking much like that Dorrito bag has got me.

I did a messenger race this Sunday. It was a good time. This is a picture of me carrying a Next MTB for a delivery. I think it weighted 35Lbs . . . Notice the double crown fork Nice touch!

I'm riding a frame I built about a month ago. it's a 3 speed specific Cross bike. It's held up to everything I could throw at it. I've bunny hopped many curbs with it . . . Hence the name "CurbDestroyer" . . . It's a sloping top tube, single speed, cross frame, with a cable stop braze on, and a modified over the top Suntour cable guide. I might post pictures later, but I already have plans for a couple more frames.

I used to ride a fixed gear everywhere, but I had this 3 speed hub sitting around and I find I really like it. Gears with no Chain Slap!

Welcome to the CurbDestroyer Chronicles

Welcome to the CurbDestroyer Chronicles

Since this is the first post in this blog, let me do it in a way that is “Me”, by using a couple statements written by someone else. It's not that I plagiarize, it's that sometimes I go against the grain of the purpose. I mean for the most part the purpose of a BLOG is the write my own statements right?

"In our culture we've been trained for individual differences to stand out, so you look at each person and the immediate opinion is brighter, dumber, older, younger, richer, poorer, and we make all these dimensional distinctions; put em into categories and treat them that way. And we get so that we only see others as separate from ourselves and the ways in which they're separate, and one of the dramatic characteristics of experience is being with another person and suddenly seeing the ways in which they are like you, not different from you. And experiencing the fact that which is essence in you and essence in me is indeed one; the understanding there is no other - it is all one." -unknown

“The whole system that we live in drills into us that we're powerless that we're weak that our society is evil ect. and so forth. It's all a big fat lie, we are powerful, beautiful and extraordinary. There is no reason why we cannot understand who we truly are, where we are going, there is no reason why the average individual cannot be fully empowered, we are incredibly powerful beings" .

This is an electronic documentation of my life, bicycle racing, and frame building trials and tribulations. Understand this. Nobody is more important than another. We simply all do different jobs. See others as your equals, nobody is below or above. If you have a passion . . . go after it. Plan it, Visualize it and commit to making it reality.

“The world is like a ride in an amusement park. And when you choose to go on it, you think it's real because that's how powerful our minds are. And the ride goes up and down and round and round. It has thrills and chills and it's very brightly colored and it's very loud and it's fun, for a while. Some people have been on the ride for a long time and they begin to question, is this real, or is this just a ride? And other people have remembered, and they come back to us, they say, "Hey - don't worry, don't be afraid, ever, because, this is just a ride." And we kill those people.”
quote by - Bill Hicks

I’m here to tell you, don’t be worried, because it is just a ride. Life is what you believe it is, you must simply believe. Remember that . . . and with that said, let’s get it on.
