Just one of many bikes I lusted for in the mid 90's but didn't have the funds for. Anyone know the story behind this lesser known Boston frame builder? And if anyone has pics, please share
Juke StainlessOur steel mountain frame has evolved over the years with many changes. Serious riders have taken them to many racing successes including six New England Championship titles, countless regional events, and completing the Iditabike. Two enthusiasts are currently riding them (into the Guiness Record book) from Prudhoe Bay Alaska to Cape Horn, in South America. Customers have raced, toured and simply ridden to work.
A custom blend of Reynolds 853, Tange prestige and True Temper steel results in a resilient, light yet durable performance frame. Why do we use different brands of steel? Because we can. Each frame size has specific requirements for weight and stiffness of each tube. Obviously the tubing for a 5’2" 120lb. rider should be different than one for a 6’2" 190lb. rider. We could use one tubeset from one manufacturer; it would certainly make our purchasing easier, but it would be a compromise for all but one frame size.1 1/8" head tube standard, 1" available.
Juke HeadshockThe Juke Stainless is built with Columbus Metax (stainless steel) tubing. This is the first big news in steel in over 40 years! We can build a lighter weight frame with the smooth ride you expect and a few benefits: No rust, no scratches, and far less impact on the environment.
Corrosion is not an issue, so like titanium, a Metax frame is a long term investment. Also, Metax frames don’t require paint to prevent rusting. We give them a finish that is easily maintained with a scotch-brite pad. Not painting the frame saves weight and spares the environment. The final benefit is purely aesthetic - we can show off our welds and workmanship. Many companies want their frames painted before you ever see them, but we are excited to have a frame that high-lights our workmanship.
Metax FAQ:Finally. The Juke HeadShok. It's built specifically for the HeadShok Fatty 70. It offers unequaled lateral stiffness and steering accuracy and a plush 70mm of travel. An ideal choice for larger riders who desire a very accurate hardtail.
---------------No Rust! The first big news in steel in over 40 years. Columbus totes this tubeset as being able to have "chromed" chainstays without the destructive chroming process. A satiny hand-brushed finish is standard, mirror-like electro-polish is available.
Tube dimensions are the similar to EL/OS, but the main tube walls are slightly thicker for greater rigidity and increased resistance to denting. The ride is superb with a zing that will never be matched by the so-called "exotics".
When we tell people about Metax, we often hear the following questions...
If it's stainless, Isn't it heavy?
Metax is stainless and exceptionally strong. Metax was developed specifically for off-shore oil drilling where high strength and corrosion resistance is even more important than in the bike industry. Fortunately for us (and you) Columbus got their hands on the stuff, since we sure don't have the budget to develop a material like this.
What does it look like?
Bicyclist magazine said "it is a steel with a brighter luster than brushed titanium, though not so bright as polished titanium or chromed steel, and it possesses the slightest blue cast, which gives it a fairly exotic appearance." We agree.
Why doesn't everybody use it, if it is so great?
Try welding it and you’ll know the answer. This stuff is tough to work with. It is difficult to cut and especially tricky to weld. Our welder spent years in the aerospace industry and welded 3000+ frames at Merlin before he could do it well. Not all companies have this kind of welding experience to draw from. We must also make all of the small parts (cable stops, brake bosses etc.) to our specifications in stainless steel.
Would you be able to braze stainless? Seems like a no-brainer way to go.Jeroen said:The problem with stainless steel is due the 'stainlessness' it self. In order to call it stainless it needs to have at leas 12% Chrome alloyed in the material. This Chrome makes the carbon in the material to glother up more, which in term makes the material brittle. Stainless steel is not the most ideal material for applications where you have a more 'spring'-like application of forces working.
Welding stainless proves difficulties in several ways as well. For starters, its very hard to maintain straight alignment when working with stainless. Cold setting isn't that easy to do and certainly not in the benefit of the structural integrity of the whole construction.
