A fork and a stem

This fork is going on a Ritchey P-21..........it will not exactly be the stock item but it will dress up the bike . The Pacenti crown and cast stainless steel dropouts are fancy hardware.
A genuine mid-90's style Rock Lobster stem for a 25.4 handlebar......I don't think I have built one of these for a few years. This will go with the frame and fork for Switzerland. At least they didn't ask me to make handlebars !

Disc brake town bike for sub 5 foot rider

These are 26x1.4" tires from Michelin. The triple crankset will come in handy for the steep hills in the San Fransisco neighborhood that this rider lives in. My guess is that the house may be up on the hill but all the shopping is at the bottom .
The disc brakes are a good way to clean up the look of the bike, solve cable routing issues on such a small frame and most importantly, provide stopping power for a bike with a load of groceries or a loaded trailer.

29er for Switzerland in process

The shop that ordered this frame Cycleworks asked for some photos of the frame in the process of being built. Here is a quick version of the build with some important steps highlighted. First, I produce the drawing.
Second, I'll machine the head tube and weld the seat tube to the BB shell.
Third, I'll weld the head tube to the top tube. I don't always do it this way but most of the time this is the most comfortable progression for me.
Next, I'll miter and weld on the down tube.
I'll assemble the two parts into the front triangle.
Next, I'll bend, cut and fit all the stays for the rear triangle. In this case i had to build a wishbone seat stay-I always do for MTB frames.
Here's the nearly completed frame and fork. I still have to build a stem.....that will be tomorrow.

Mystery gift

This sculpture made entirely from bicycle parts showed up at my shop while I was at NAHMBS. I contacted the usual suspects and have not found out who made it or who dropped it off. I am thinking of hanging up in front of my shop.....it's really pretty amazing.

The shredder

This customer requested that I try my hand at painting on the logos rather than the standard decals. I have not done this sort of thing for a good many years....I guess if it does not make the cut it can easily be removed ! When I first started building I used to always hand paint on the name....I had no decals nor money to have them made.

Travel bike # 3

This frame will have to wait for a fork to be built. I had to source dropouts from the U.K. and am waiting for their arrival. This is essentially a team tig euro with disc brakes.
The old wavy gussets are making an appearance on this frame and the Columbus rear stays came with the s-bends so I saved a little work. These seatstays are a bit larger diameter than normal to resist the twisting forces of the brake.

Taking the long way home...

About half way home from work I came across about seven wild turkeys just off the main road through Grey Whale ranch. I just happened to have my camera with me so I took a coupe of shots. Too bad my camera does not have a really good zoom.......actually it has a really bad zoom. I guess that's what you get when you buy a camera at a drug store.
This guy had his feathers all spread out until I pulled the camera out.
