AZ


 Desert critters out at NRA
 My bike chills out on a skateboard chair at Les' lot. I've got two different cranks and pedals because it is apparently possible to bend just one side. I cased a big transfer jump, my pedal gave out and the crank arm reached permanent deformation.
We took a run down south mountain on the big bikes. Back in the closet she goes for another year. 

Billy and Tony inspect some work at Les' place.

 Billy gets it done on my AM hardtail at Papago
Tony X-ed up on the funnest step down.

Steves 22

I'ver done so many low standover (6.5-7.5") frames lately that a normal 8.5-9" looks weird to me.

Neon

is hard to photograph. Looks too muted inside and a bit too florescent outside. The actual color is about the same a tennis ball.

Redbel

the Redbull urban rythm/jam (BMX demo) in Houston was nuts. They chose last Friday night while it was forty degrees and spitting rain out, but they managed to get it done... All for the sake of having fun and showing off. Bezanson was killing it on the vert wall / 22ft tall building

goofy little BMX

This frame will require this little special cable hanger to clear the back side of the seat tube 



I was instructed not to put housing mounts of any kind and that "he would be modifying it himself", but I doubt he'd weld an insert all the way through. Drilling a hole through the seat tube (below the top tube) would be a huge stress riser if not done properly- lots of twisting forces and tension in that spot. I had initially planned on using an adjuster screw, but I placed the hole too far down for it to work. The housing fits really snug in there and it should work well irregartless.

 The AM Stout/Kona feels about 10lbs heavier than the SS hardtail. I don't think I'll be riding this pig at my local trails too much... at least not with the 2.7 DH tires.

Some tight clearances 
Finally got around to trying the Faction 22 tire. I was a little worried about the folding Kevlar bead, but its a really solid tire. Faction warns that one should always use baby powder, between the tube and tire, to prevent blow-offs. 

Gotta find a few more parts but shes almost back together. I had forgotten how long the rear ends of these frames were: 18" chainstays. The slope frame I made has 15.7" stays.

nother weekend fully project

I had some 83mm Spanish BBs made for frames with super short chainstays. I have 83mm Euros on a few of my bikes and they work out fine with a 6" Profile spindle. I also just got some butted (27.2mm post) seat tubes which will work with frames that have a higher standover-12- 14" center to center
This shorter integrated HT cut off 25mm of stack height.



Dragged the old Kona out and learned a few things by reverse engineering the pivot points. The old front triangle was due for a catastrophic failure... this one should last longer than the rest of its parts. A few improvements over the original are a 1.2mm thick, heat treated down tube, a 31.6mm post size (for my current dropper) and a lower stack height achieved with the integrated headtube.

Working on lots of these little racers.

Nate

pretty happy with the weight of this frame. It has a heat treated, 1.5' dia, straight gauge DT which would normally put the weight over 5 lbs but the Supertherm seatstays brought it down to 4.9 lbs. So its strong and dent resistant in all the right places.

Square

Sometimes I make a standover that is too tall or something and I end up with aborted front triangles laying around. I decided to experiment with rectangle tubing as a yoke/monostay.

Rectangular tubes are much easier to work with than round tubes: No tube blocks required for hole saw notching, and the stay miter is a flat cut. That little tube insert is for looks but it probably helps stiffen up the mono-stay a little too. This type of stay would work well with removable chainstay brakes as the square tube is low profile and doesn't present any clearance issues (like a 1.5" round mono-stay does)

This is a trails 22" wheeler that will be for sale once I get around to coating it. Here are the numbers:

 21" TT
74.25* HA
13.75" CS
68mm Mid BB
Straight gauge DT/ Supertherm TT
12.6-12.9" BB height (+1.55")

Benton's huge street 26"

This ones got a steep SA and a super long TT because tall people don't belong on a one-size-fits all frame... Not that there are any left hand drive specific, 110mm spacing, stock frames out there anyway
