  • 653 or 853 or lighter and thinner, but more fragile. 531 is a good comprimise. AWESOME!

    653 tubeset is just a mix of 753 and even-thinner-than-usual 531.
    Apparently 753 was found too harsh by some tour riders.

  • Apparently 753 was found too harsh by some embittered, losing tour riders./geek


  • I'm only keeping this thread alive in case someone will actually print
    '531 is awesome!'

  • I reckon Dale could be convinced to pay for the screen setup and a batch of 50.

  • I wonder what tubing was used on the geekhouse?
    It is probably not as awesome as it could have been.

  • dedacci and columbus

  • 'deddacciai is kindof awesome!'
    In 30 years time when you aren't as flexible and I have started shrinking, can I buy the geekhouse?

  • there's already a list, you can be 3rd ;)

  • I've got both so I'm entitled to vote. 531 wins.

    'Alunoonium' and its alloy derivatives are fine if you want a rigid frame and don't care about ride feel or life span.

    ya, I also find the numbness that aluminium frames produce can really cause problems with "ride feel" and "life span"

    Gotta ride steel if you want to keep your vital organs vertically stiff yet laterally compliant

    Er, yeah...

    (riding 250 miles a week on aluminium during 'conceptual' phase of my relationship)

  • Carbolite. End of thread.

  • Tried to rep you Dogs, but this rep system is racist, and fattist (I can't rep who I want to).

    Good insight into 531 and such.

    Where's the rep for my googling. Hmmpf!

    Anyway, I found this website to be one of the most useful for debating frame materials:

    Eat my google! :P

    **Tubing ** **Material ** Ultimate Strength Minimum Elongation Description STEEL Columbus Life/Spirit Niobium 177-205 KSI14% minThe extreme strength of this alloy allows Columbus to draw the tubes to thinner specifications than ever before, down to 0.38mm! The chemical makeup of this alloy produces excellent hardening and reduces the sensitivity to overheating by maintaining a fine-grained structure. This tubing is marginally heavier than aluminum while still possessing the strength and ride qualities of steel. Spirit tubes are 20% thinner for even more weight savings, and also offered in special shapes. Columbus Zona Nivacrom 134-149 KSI 10% min Nivacrom alloy has been developed especially for cycling with all considerations taken. The asymmetric double-butted tubes go through a series of treatments that homogenize the mechanical properties, giving the tubes great fatigue behavior and weld ability. This tube set produces a bike of moderate weight and notable strength with a compliant steel ride. Reynolds 953 Carpenter Stainless Steel 255-290 KSI NA This is Reynolds new ìSuper Steelî. Using what is at this time the strongest steel alloy Reynolds is able to make seamless butted tubes with exceptionally thin walls down to .3mm. 953 should be able to produce a sub three pound road race frame. Because it is stainless steel it is corrosion resistant and also can be polished. Appropriate for either TIG or brazed construction. Reynolds 853 Proprietary Air Hardening Heat Treated 180-210 KSI 10% min Reynolds853 is made from a seamless steel alloy originally developed for the side impact beams on high performance cars. The term ìair-hardeningî refers to a special category of steels that when welded and allowed to cool in air, actually get harder in the weld area. Because this is normally the critical zone for fatigue life, 853 frames will out-perform conventional steel alloys due to this innovation. Reynolds 631 Proprietary Air Hardening 115-130 KSI 10% min This is the upgrade form the legendary ì531î steel. The strength has gone up 10% allowing weight savings on tough, durable but comfortable frames. Perfect for the long distance tourer or hard-tail MTB where ride feel and toughness matter. Reynolds 725 25CrMo4 Heat Treated 157-186 KSI 10% min Using an industry standard steel alloy, Reynolds mandrel butt and then heat-treats this alloy. 725 can be TIG welded and can also be using in a ìDesigner Selectî combination with Reynolds air hardened range of 853 and 631 tubing Reynolds 525 25CrMo4 114 KSI 10% Mandrel butted for accurate profiles and available in a number of shapes, 525 offers a tube-set with strengths similar to the famous 531 range. True Temper S3 Proprietary Air Hardening Heat Treated 150-217 KSI 10% min True Temper's newest steel tubing is the S3 Super Strength Steel Series. This alloy makes possible top tubes and down tubes having end butts of a weight shaving 0.5mm and center sections of 0.4mm. This alloy with its special heat treatment is used to create the S3 Super Strength Steel tube set. This makes a compact style (sloping top tube) frame that weighs only 2.85 pounds (1295 grams) for riders who want the lightest weight possible. True Temper OX Platinum Proprietary Air Hardening Heat Treated 135-185 KSI 10% min True Temper's premium steel tubing is the OX PLATINUM Series. The high strength of the PLATINUM alloy make possible top tubes and down tubes have end butts of 0.7mm and center sections of 0.4mm to minimize weight. In recognition of the needs of Custom Frame Builders and their customers, each main triangle tube comes in a range of wall thicknesses and butt lengths so builders can fine-tune the frame's stiffness to their customer's needs. True Temper Verus HT 4130 Heat Treated 150-175 KSI 10% min True Temper's VERUS HT Series tubing is made possible by True Temper's decades of experience in the heat treatment of 4130 steels for maximum performance. As steels are strengthened by heat treatment, the ductility is reduced. If you were to heat treat 4130 steel as hard as possible, the tensile strength would go all the way up to 255,000 PSI. But the steel would very brittle and subject to failure by fracture, making it unsuitable for bike frames. The metallurgists at True Temper designed the VERUS HT heat treatment to reach the high level of 175,000psi, while still maintaining good ductility. True Temper Verus 4130 110 KSI 10% min True Temper's VERUS Stress Relieved 4130 steel is designed for reliability that is even better than commercial grade 4130. This heat treatment removes internal stresses left over from the manufacturing process. The end result of removing internal stresses is that the tube (and your frame) lasts much longer. Dedacciai EOM 16.5 Micro alloy Low carbon N/A N/A The EOM 16.5 tube sets are made with a low carbon content that is ideal for welding. After the tubes are formed they are then austempered in a low carbon atmosphere, after which they undergo external surface tempering. Dedacciai SAT 14.5 18MCDV6 Micro alloy >203KSI 13% min A heat-treated Micro alloy. Both extremely light, and super strong, this tube set possess excellent fatigue characteristics. Available in standard and oversize tubes. TITANIUM Ancotech 3Al/2.5V Titanium 3Al/2.5V 90-95 KSI 15% American titanium with straight wall tubing offers a worry free lifetime frame. Tube diameters are available to produce a frame as stiff as desired or conversely, as supple as imagined. Frame weights are typically lighter than most steel tube sets. Reynolds 3Al/2.5V Titanium 3Al/2.5V 90-95 KSI 15% Reynolds as a lighter alternative to straight gauge tubing offers double-butted titanium. Thicknesses are down to 0.6mm on mainframe tubes. This tube set will build a very reliable, lightweight, and excellent riding frame that will last a lifetime. Reynolds6Al/4V Titanium 6Al/4V 130-145 KSI 10% min The added strength of 6/4 titanium allows it to be drawn out thinner than 3/2.5, resulting in a lighter frame. ALUMINUM Columbus XLRBR Scandium Aluminum Doped w/zirconium 80 KSI 12% min This aluminum alloy uses zirconium to reduce grain size and improve strength, which enables tubes to be drawn down to 0.6mm. Recovery of mechanical properties after welding is achieved through a 20-hour ageing process. A high strength to weight ratio along with radically shaped tubes yields a very light bike with good reliability and comfort. A great tube set for nearly all race applications. Columbus Airplane Aluminum Zn, Mg 61 KSI 10% A light tube set that is well suited for track and time trials. Aero shapes are offered for all main tubes, including a teardrop seat tube with a radius cutout to accommodate short chain stays common to track bikes. Mechanical properties are recovered after welding through a 10-hour artificial ageing process. Dedacciai U2 Proprietary Aluminum N/A N/A Radically shaped and drawn aluminum alloy for weight savings and stiffness. This material uses elements from the rare earth series to block grain growth and increase strength. A very light tube set intended for road racing. Easton Scandium Sc7000 71 KSI 13 % Designed for the highest ride quality in the lightest package possible. The Scandium-enhanced aluminum alloy produces an even finer grain alignment, increasing the strength of the aluminum. This tube set yields a very light, responsive yet supple ride for road or MTB. Sc7000 is also offered in Aero shaped tubes. Easton Ultralite 7005 59 KSI 15% With unparalleled fatigue strength and superb ride characteristics, Ultralite is a high performing lightweight tube set available for road and off-road racing or lightweight enthusiasts. Easton taper walls have the smoothest walls in the industry along with consistent butts.

  • I reckon Dale could be convinced to pay for the screen setup and a batch of 50.

    Put me down for one please. =)

  • the space shuttle is made out of it too

    and the moon

    Best.... piss taker.... EVER.

  • ya, I also find the numbness that aluminium frames produce can really cause problems with "ride feel" and "life span"

    Complete bollocks. Oh wait.. I hope think you were taking the piss.

  • Just realised I have a spare original 531 seat tube sticker if anyone wants it.

  • I would like (Need) a 753 sticker if anyone has one?

  • I've got some Raleigh Club 18-30 stickers if anyone wants them. They have a crumpled frame attached.

  • I would like (Need) a 753 sticker if anyone has one?

    Try H.Lloyd.

  • Good site, ta P.

  • there's already a list
    HA!!! I knew it was only a matter of time!!!

    Thats one down, and 2 to go. Welcome to the brotherhood of List Makers, Brother Dogsballs.

  • Can anyone shed any light on what this tubing is like please?
    Dedacciai CrMo Acciaio Legato Tubing

  • well it means Dedacciai Chromium-Molybdenum Steel joined tubing, so it's more of a description than a tubeset, if that's any help.

    There are tubeset names as well such as SAT 14.5 and EOM 16.5, so if it doesn't have those it's likely to be standard cro-mo steel, not bad but no Awesome (tm)

  • Guess: prolly similar to COM 12.5?
