You might see this one again but I can't say where just yet. It has a couple of tubes of Scandium, the rest being 7005 aluminum. There are some Ahrens sliding dropouts and it is a disc only bike just like the one Aaron Bradford rode to the National championship in 2012 and the silver medal in 2013. I guess you could say that it is a proven design but also that the motor was proven as well.
The main difference is that this one does not have provisions for rim brakes and it will take a tapered steerer.
It will be raced....you can count on that.

Columbus Max road frame for the U.K.
Wow....another one ! Could it be that Max is making a comeback ? Looks like it to me. I enjoy working with it and that Columbus metal has the mythical ride that stumps framebuilders and engineers alike. Nobody can really articulate why it rides the way it does. This is as it should be......something nebulous and undefined but still a thing that one can notice.
Steel tig welds
Here's some pretty decent looking stuff from last week. I have been using my newer welder for about 10 months now and am pretty comfortable with it. Maybe some day I'll be nearly as good as Mike De Salvo !
For the people that wish to know, this is a mid-'90's Miller Syncrowave 250 and I do not have a pulser. I use a 3/32 " ceriated or lanthanated electrode most of the time and have a gas lens. I use about 18-20 PSI pf Argon and use the 'dab' method for adding rod. This is all primitive style by current standards but if I get results like this I guess I'm doing o.k.

Tom's ride 2013
It was going to be about 90 degrees so the group did its best to get up the first climb before the heat really set in.Here's us at the top of climb # 1 at 2,450 '.
Here's a view of the mountains just starting the descent down into the valley.
Brent on his recently resurrected '70's Motobecane Le Champion. The triple crank came in handy on the grades.
This group of buildings is a simulated middle eastern village......the military was doing maneuvers here a couple of years ago-maybe a rehersal for something........use your imagination.
After the river crossing the group neared the lunch spot-a swimming hole at the base of the final dirt climb. It was really hot at this time of day and people were definitely feeling it.
A dip in the water helped counteract the effect of exposure to the 90 degree sun.
Meanwhile, the bikes were left up on the road, not getting a frosty dip in the cold waters.
Most of the way up the climb there was a big rockslide. This was a bit of a hike but the fact that it is there prevents car traffic. This makes for a downhill where you can really let it fly.....no worries about traffic coming the other direction.
This is the last water stop at the Arroyo Seco campground. The store was closed so we had to make do with the not too great campground water. Everyone was cramping at this point so the water really saved us.
At the end of the ride even my camera was so tired it could not fully open it's eye !

Proto track bike for local rider
This is probably the first bike that I have built under 14 lbs. It is 13 lbs. 8 oz. It really feels like it when you pick it up. It does not feel flimsy when you ride it, though. This is made from Easton 7000 tubing.
7005 29er bound for Flagstaff
This one is all Shimano XT except for some Mavic SLR wheels. The post, bar and stem are Easton Haven....bombproof yet still pretty light. With tubes this bike weighs 25 lbs.

Road frame for L.A.
This one is nice and stout for the streets of L.A. where surprisingly a bicycle culture is emerging. Funny , it wasn't that way when I lived there 30-some odd years ago. You see lots of folks riding everywhere. Maybe you'll see this one !
