Hand building bike from start to finish!

Frame Material

At DEAN we use only the finest titanium available:

- U.S. made 3/2.5 seamless, cold worked, stress relieved - grade 9 titanium.

- Our radially butted 3/2.5 CWSR titanium tubing is CNC machine to precision tolerances.

- Our 6/4 seamless titanium is precision machine butted by Reynolds.

DEAN Titanium consists of 3% aluminum, 2.5% vanadium and 94.5% pure titanium. Exclusive to our titanium is the "R" grade processing. This allows for radially aligned crystals. This dramatically increases strength and durability.

Titanium possess a minimum yield strength of 105 ksi and a minimum UTS (ulitmate tensile strength) of 125 ksi. It has a annealed elongation of 15-20% and a cold-worked ductility of 10%. Titanium has a fatigue strength-to-weight ratio roughly twice that of 4130 cromoly steel. As well as it has superior resiliency and corrosion resistance.

Craftsmanship

Each and every DEAN frame is handcrafted one by one, in our own factory in Boulder, Colorado.

We cut every tube with precision cutting tools to assure proper frame fitup prior to going into the fixture.

After the cutting process - every tube is hand filed and cleaned prior to the weld process.

Frame Setup

At DEAN we believe proper setup is essential to precision frame alignment, strength and durability.

We make sure each and every frame is thoroughly checked through our D.Q.C. assurance program.

Each frame must pass our D.Q.C process prior to being fixurted - this assures proper aligment prior to weld.

Welds

We take great pride in every weld on our (your) frame.

1.) Each and every frame is first "root" or "fusion" welded in our precision aligned fixture.

2.) After the "root/fusion" weld our welders work there magic with a 6/4 titanium rod cap pass.

3.) On every DEAN you're assured only the most structurally sound welds - as well as perfect cosmetics.

Frame Alignment
After weld, each and every DEAN is aligned to a 1.0mm standard and must pass our D.Q.C. process before going on to frame finishing - this assures only the straightest frames make it out of our doors.

If you have additional questions please do not hesitate to contact us - we can be reache via 1-303.530-3091.

We look forward to building you a great bike!
