In college, I started to do a little bicycle framebuilding. For amateur builders like myself, getting information and sources for supplies can be difficult. So if you're interested in getting started yourself, I've put some links up here so you don't have to do all kinds of searching. In addition, I've got photos of my own work to provide some ideas for other aspiring builders.

Tubing manufacturers


True Temper OX Platinum

Henry James is the industry leader in bicycle frame jigs, and has just released a new model.
Henry James lugs are some of the best available.
Henry James is the #1 distributor of True Temper tubing.
Henry James also sells braze-ons, silver & brass brazing rod, flux, etc. Pretty much everything you need to build a frame.


Reynolds USA
Reynolds is a British company known for their new 853 steel tubing, which gets harder and stronger after welding or brazing. They're also just starting to get into carbon fiber, aluminum, and titanium. You can order tubing directly from their British office.


ColumbusColumbus is an Italian company that is probably the biggest, most diverse company around. In addition to regular tubesets, they make stainless steel and aerodynamic tubesets. The company also offers aluminum and titanium tubes. You can get Columbus tubing from Nova Cycles (see below), Ceeway, or from Joe Bringheli.

Deddaciai 0.1

Deddaciai is an relatively new Italian company that makes really great steel and aluminum tubing. I used their Zero Uno steel tubeset for my new road racing frame (see below).  You can get this tubing from Joe Bringheli.


Excell is a French tubing manufacturer that makes some very light road tubesets. Giordana frames, sold by Gita in the United States, uses the Excell Podium OS tubing in a 3.5 lb. road frame. Good stuff.

Vitus is a French company that made some nice steel tubing, but are more well known for they're aluminum bikes. Few people build with it here in the U.S. anymore, except for Harry Havnoonian and maybe Rivendell. Last I heard, Vitus was halting steel tubing production in order to focus on aluminum bikes.

Carpenter Technological Corporation makes a new super-stong steel alloy called AerMet 100, but it is exceedingly hard to get ahold of. In addition, few people build with it.

Easton is an American company that makes aluminum tubing. They've got some fantastic new tubing that uses Scandium to increase strength so that smaller diameter tubes can be used.

Alcoa is another American company that makes aluminum tubing, most notably for Saeco/Cannondale's pro road team. Unfortunately, they don't sell tubesets to individuals.

Ancotech is an American company which is probably the largest supplier of titanium tubing around.

Wicks Aircraft Supply sells plain 4130 Cro-Moly tubing, good for making brake bridges, stems and other miscellanious frame projects.

Wooley Fabrication makes some great tubing blocks, including some blocks that have more then one size tube hole within it.  great idea!

Paul Component Engineering produces some really nice steel rear track dropouts.  They even come with built-in adjuster screws like the classic rear horizontal dropouts of yore.

Strawberry Bicycles makes a cool internal seat binder bolt mechanism, perfect for those fillet-brazed road frames. 

Kavik Bicycles now makes modular dropouts.  Once the base of the dropout is brazed into your frame, you can then bolt on different dropout variations; for example, you can start with a vertical road dropout and then change to a horizontal track drop.  Cool stuff.

There are many framebuilders out there that really produce fine frames, pieces of artwork. The following list is only a small representation of them. Looking at their frames is usually a good way to get ideas for what you want your own frame to look like.  In alphabetical order by last name.


Painting and/or Chroming
