Silk Ti Breakaway Race Proto

This is a Silk Ti Breakaway I made for Tom Ritchey to race in Europe. He wanted a bike he could carry on and not loose. It features Tom's integrated head tube, and his Breakaway technology, with the Castellano Silk Ti technology. Fun bike to build and a fun bike to ride! Brennan has his eye on this one, he is quite the bike collector!

Have You Seen This Before!

This is what you get when someone wants a Single Speed Silk Ti with Paragon Sliders. Thanks to John Castellano's design and engineering skills when it comes to solving new challenges with this custom request!

Touring Sideview

Steve Potts custom made frame and fork with rack and fender mounts front and rear.

Full On Touring !

This bike is going to be a hard one to let go! It is set up for front and rear racks and fenders ! The totally functional bullet proof bike !

Big Tire Clearance!

Lot's of room for the big fat tires on the new 29er SS!

Sliders!

Sliders for the 29er Single Speed.

New Ride for Matthias!

Matthias's new 29er Single Speed! I think he may be up all night putting this one together !!!!

Untouched Welds

I just had a customers friend ask if the welds were polished, or welded by a robot, I had to tell him the Robots name was RoPotts, just a guy that loves to build bikes up in the shop.

New Life for an Old Bow Ti

Ready to go home and do some more riding!

Bow Ti Restoration

It sure is fun to get the old Bow Ti's back in for new disc mounts and a complete restoration!

Finished Disc Tabs

This is what the tabs look like after being taken out of the plate, they still need some hand finishing and bending to fit the frame.

Titanium Plate Waterjet Process

This is what is left of a piece of titanium plate after the waterjet process has cut out the disc tabs, incredible technology! This type of machining allows you to get as many parts out of the plate as possible because you do not have to account for the thickness of a cutting tool, just a very small stream of high pressure water with a fine abrasive introduced into the stream of water.

Titanium Cross Breakaway

Together and ready for assembly!

Titanium Cross Breakaway

Fits nice in a carry on case ! Don't loose your bike when traveling.

A Wonderful Gift

It is a special gift for a father to see his children grow in healthy creative ways. It seems that my sons Daniel and Brennan( in photo) , want to build everything, just like someone else I know. As I get older, I realize how much I learned just watching my father in his shop building things, and he built everything! It really does seem to get absorbed by just hanging out with your Dad. I am thankful that my sons like hanging out with me, it seems like they are catching on to building their own ideas! What a pleasure to see!

For Those Folks That Enjoy Music!

I got a 3 day wonderful visit by my long time friend Bill Cobham and his wonderful wife Faina from Switzerland. It was a great treat to spend time with them!

The Fit and the Fusion Weld

Tight miters with part of the first pass fusion weld ( no added welding material), essential for a strong weld joint.

Up Close S@S Coupling

The S@S coupling is a beautifully engineered and machined component.

S@S Silk Ti

Here is a beautiful S@S Silk Ti for those who know how to travel.

Bow Ti Fixture

Just a glimpse of the Castellano Bow Ti fixture, just for the curious bike enthusiast!

Silk Ti's...

Some Silk Ti's in the final stage of manufacturing.

A Lot of Silk Ti's going on!

Along with my duties building Steve Potts Bikes, I also build all of John Castellano's frames for Castellano Designs. I build the Silk Ti, Bow Ti, and his new Zorro. I have been doing this for several years and really enjoy working with John. When ever John makes it to my shop to work on his bike projects with me , both his arms get twisted by my sons Daniel and Brennan to make dinner. Not only is John a great bike designer, he is also a great cook!

Up Close Detail....

A close view of the silver soldered crown to fork leg joint on the Type II Fork.

Type II Drop Out Detail

The Type II drop out detail, lots of work in these puppies....., nice color!

Disc Details!

Type II Disc details, .........

Type II with color!

A little bit of color for the Type II Fork fans!

Type II Fork, another classic.

Still swamped with building the Classic Type II Fork. I'm certainly not complaining, but when you work alone it's hard to keep up with the details of the custom built fork and frame. Every fork in this photo is different, just as is every frame that I build is different. It sure does keep you on your toes!

More Classic Stems

Here is some more of the old classic stems for a restoration, man I used to build a lot of these, they sure are a lot of work!

The Old Stuff!

I seem to be getting a lot of request for making the older parts I used to make so much of. It's great to see people restoring those great old bikes! These are some stems for an old tandem.

Mount Tamalpais

It is only fitting that Mount Tam ended up as my headtube badge as it's beauty inspired my passion for cycling since I started exploring it's slopes and trails from about the age of 10 years old. I remember feeling like I just discovered the wild west, I was sure I was the only one who knew about this great place! These headtube badges were made intirely in my shop , thanks to the help of great friends and craftsmen, Dave , Uve and Joyce. We made the machinery and used brass that was too short for me to braze bikes together , melted it down and made headtube badges! Yes it was a bit more involved than just described, but really just wanted to say thanks to all those who inspired me and helped along the way!

More 29er,,,Sliders.....

More 29er SS with the Paragon Sliders, a great drop out for single speeds! More photos to come.

More 29ers !

Here are a few more 29ers, single speeds, with traditonal track drop outs. Lightweight precise handling, more fun on the way!

Simple is good!

A lot of people are enjoying the precise handling of a rigid 29er with the Type II Fork. I seem to be making a lot of these now. They sure are fun!!!!!
