I decided to sponsor a local high school racer. Max is a crazy fast 16/17 year old kid. He had frame sponsors for everything but SS, so I jumped on that.

Note: The bike is not set up with race parts as shown. We just needed it to get up and running to dial in the setup before the fancy bits get ordered.

That is a nice looking ride for that youngster. Nice colour, nice dropouts, nice all round.

At the risk of sounding like a moron, is this a 26er or 29er? At any rate it looks good. I wonder about the gusset, though. This style of gusset was popular in BMX 10 years ago, and proved crack-prone.

Is there a point to 'sponsoring' his aside from the warm and fuzzies, because it's not like you're making and selling anything.

Are you?

does there need to be another reason? i "sponsored" by buddy's 15yr old last year with a frame & it still makes me feel good. when you make your own stuff you can do this kinda thing without shelling out a bunch of $$$$ for someone else to make it for you. believe it or not, just being a considerate nice person shows *and* is the best advertising you can{not} buy............holiday spirit, right? :thumbsup: Steve Garro, Coconino Cycles.

Tire size is 26, shown on the sketches on PVD's web page. I am curious though.. what are the riders dimensions and weight? (Peter, I'm interested in the tube selection process.. why did you go with what... I'm benchmarking for my own personal build...)

and hey, on the gusset thing. I'm working hard right now to add that gusset ( + more) to the tubenotcher web page... Peter, was this the bike that sparked you to ask for that feature?

Yup. I'm really not a fan of gussets, but I've got to do something to brace the bottom of the headtube when I'm moving the DT up to dodge the fork crown. There is plenty of butt behind the gusset to support it. (I hope). I may end up doing this kind of thing a lot more if this works well.

When we tested this rider on one of my regular bikes, one problem was getting more power to the pedals for SS racing. Most of my bikes are trail bikes for my area. They are extremely flexible to hold onto the singletrack at high speeds. Max needed the frame a little stiffer for power transfer but still keeping the trailholding nature of the flexible bikes. I revised where and how I bent the chain and seatstays for more mechanical stiffness. I also figured that the gusset would help reduce twisting the frame while wrenching on the handlebars. I wanted to save money and use cheap tubes, but I also figured that using 8/5/8 instead of 7/4/7 main tubes would give a subtle increase in stiffness. I toyed with doing a 1.500" DT but decided not to at the last minute to keep weight down and for fear that it would be too much. The headtube is also as long as can be to fight shudder under hard braking. All of this is fairly subtle stuff, but we were really trying not to ruin the benifits of the flexible frame, just get more power to the rear wheel.

No. I don't sell bikes. The way I see it is that we all try to do good things. Some people are political, get new trail built, throw parties, coach high school leagues. I'm a geek. My special gift to the world is making this kind of stuff. I figured that I could do this. Show the young people in my area what can be done by someone that they know. That not eveything in biking is to be bought or sold. I also grew up skateboarding, motorsport, and riding bikes where local talent goes on to be pro or something really cool. A lot of people have to support people in odd ways for them to get ahead. I've always tried to help.

In my opinion you should'nt of had to explain this. I do stuff like this all the time as well, it's important,
but since you took the time to write an explanation I thought I'd let you know that your explanation was spot on and well written.

Anyway, bike looks great, its got an awsome stance. That kid must be over the moon!

"Some money was saved while constructing this bike. I'm sure that the frame would weigh over half a pound less if another $125 was spent on tubing. Most of this project was about geometry and ride quality rather than cutting edge low weight. If need be, another version can be built that is much lighter...

Frame - 4.07 lbs w/slider Ti hardware and SS bottle cage bolts."

4.07 lbs seem like a reasonable weight for a steel frame. When you phrase it like you do above, it makes it sound like other custom builders don't spend enough work on fit and ride quality. Do you really feel that way?

I know I'd rather have a good fitting and good riding frame with generic tubes than a lighter bike any day.

I love the slack STA, I need one like that.

If you'd care to research you'd know that during the past couple of years I've had up to three guys racing for me at any one time, so I don't know what your point is. And to top it off, these are people that could probably get factory rides because periodically they are up there duking it out with much better funded and experienced riders.

In fact, my #1 criteria for helping someone out is "Are they good people" and I've actually rejected 'better' riders simple because they're nongs.

My question was levied at Pete that way because numerous times I've enquired about some of the cool bits he's threatened to sell to us custom frame guys and nothing has come of it.

Talk to us about that looong post. I know you have a reason for it...
Yup. It follows with the flexible flyer theme I like to use. By using a carbon fibre seatpost with a lot of extention, you can gain a large amount of compliance and energy store before it enters the frame. This helps the rider stay seated more and longer. It's really impressive when you see how much one of these EC90 posts can flex. AL or TI wouldn't work well for this because they will take a set if they bend too far. We've all seen this happen. Carbon won't do that. It keeps coming right back. I've been doing this for several years and it works great.

Love the lines on this build - I've always been a fan of higher front ends and shorter seat tubes. It lets me slam the seat when something "fun" is found on the trail. Very interesting about the carbon seatpost flex. I might have try one.

And big props for hooking a 16 year old kid with a frame. I think I'm about 16 in that pic on my avatar and wish I could go back to that timeframe of riding everyday. Looks like that build will help Max with some races this year.

How did you change the seatstay/chainstay bending process?? Are they vertically compliant? Would this work with a rear cassette? Did you think about going to a 150 mm rear? Keep-up the interesting work!!

Wow - other than tires that thing looks like it would be pretty raceable just like it is! I imagine you are probably going to a lighter fork and maybe wheels/tires? Nothing wrong with an XT crank and the other stuff that I can see. Clean-looking frame and nice color! I hope both your and his efforts are rewarded with good results and fun rides!
