TANGE—THE WORLD LEADER IN FORK TECHNOLOGY
Tange’s Advanced MTB Fork System
Tange has developed a new mountain bike fork system that provides more control, safety, and performance to the off-road racer and mountain bike enthusiast. Specify the new active suspension Shockblades, Struts, or Ultralight Forks as replacements or original equipment. You can always be sure of Tange quality, durability, and performance.
Shockblades
Tange’s active-suspension Shockblades offer a dramatically improved ride and enhanced control to the off-road cycling enthusiast. Utilizing the finest in materials and proven designs, Shockblades deliver exceptional shock absorbing performance without sacrificing strength, durability, or control.
• Materials:
Fork Stem;
Chrome-moly steel
(Titanium option available in 28.6mm and 31.8mm diameters )
Crown;
Heat treated aluminum alloy
Blades;
Heat treated hard anodized aluminum alloy
• Active Suspension Element:
Maintenance-free compressible elastomer
• Travel: 38mm
• Lower Length: 430mm
• Weight:
Cr-Mo 1247g (2 lb. 12 oz.)
Titanium 1077g (2 lb.
Struts®
Tange’s new patented Struts® offer fresh style and exceptional strength along with increased comfort and control.
*Designed in cooperation with
FAT CITY CYCLES
• Weight:
Cr-Mo 880g (1 lb. 15 oz.)
Titanium 630g (1 lb. 6 oz.)

Ultralight Fork
Unlike conventional one-piece forks, a new bending process is utilized in order to maintain an even wall thickness throughout the bend. This means fork weight is further reduced without any sacrifice in strength. Furthermore, control is enhanced as a result of special investment fork ends and the large tapered diameter blade cross section.
• Weight: 810g (1 lb. 12 oz.) 160mm length

Thinner outer wall
Thick inner wall
Ultralight Fork

Big Fork (MTB)
The original…Large diameter untapered butted blades and offset investment cast fork ends. Big performance!
• Weight: 900g
*Weights are at 160 mm stem length.

TANGE
Tange Prestige Tubing
Prestige is a high grade chrome molybdenum tubing which is subjected to a special Tange heat treating process. The result is a very light high-strength tube for performance oriented bicycles.
Tange Oversize Tubing
Large outside diameter of Tange Oversize provides significant increase in strength with a minimal weight increase. Tange Oversize makes a more rigid and efficient frame.
Tange Taper-Butted Tubing
Tange Prestige OS mountain bike tubing features double butted construction. The difference is that one butt utilizes a tapered design in which the wall thickness of the butt itself tapers toward the center of the tube. A stronger joint is realized from a very lightweight tube.
Taper butted tubes maintain joint strength while decreasing the weight of the tube set.

Taper Butted End
Center Wall
Straight Butted End
Short Butt Taper Tubing
Tange offers short tapered butts on tubing specified for TIG welded frames. The length of the butt can be effectively reduced due to the shorter heating time utilized with TIG welding.
Bulge Butting
Bulge butting adds material to the outside of the tube at the top of the seat tube and at the fork stem in order to increase tube strength at the joint. Bulge butting eliminates the need for additional reinforcing pieces.

THE ULTIMATE IN PRESTIGE TUBING
The Tange Frame Component System
The frame design determines the performance of the bicycle. And the tubing determines the performance of the frame. Sixty years of accumulated expertise in the development of bicycle tubing stands behind each Tange frame tube system. Tange now offers many new and advanced frame tube systems that are setting new standards for the cycling world. When you ride Tange, you’re riding a frame with a pedigree.
Ultimate Tubing
Ultimate is a new line of Tange bicycle tubing born from Prestige technology. The use of special heat treatments and unique tubing configurations increase strength and minimize weight to provide a new level of tubing performance. It’s the new “ultimate” in Tange tubing.
Ultimate Ultralight Tubing
Unlike conventional butted tubes, Ultimate Ultralight features a greater difference in wall thickness between the butted and non-butted portions of the tube. The result is significantly reduced frame weight without any reduction in joint strength.

Ultimate Ultrastrong features external ribs and internal butting at the tube ends. This results in even greater frame strength without adding unnecessary weight.
