nope 아래등급이군요... 튜빙은 컬럼버스 LIFE라는 튜빙이고 만약에 카본보강재가 들어간거라면 nope과 같은 최상급 SPIRIT이라는 튜빙인데 똑같은 NIOBIUM이란 카테고리안에 들어갑니다. 예전엔 nivacrom소재의 zona가 최상이었으나 신개발을 한것이죠...nope은 SPIRIT튜빙을 쓰고요... 그에 뒤질세라 레이놀드에서 최상급853에이어 최근 953개발후 953이 상용화가 안되어 사실 853은 SPIRIT이나 LIFE한테는 특히 무게면에서 절대 못따라오는 한계가 있습니다. 탄성면에서도 앞서구요... 레이놀드953이 나오면 탄성이 853보다 무려2배에 무게는 로드바이크기준 1000g밑의 프래임이 나온다고 합니다. 크로몰리가!^^ 거기다 녹이 슬지 않는 스텐레스! 비교가 안되는 탄성에 무게에 가장 프래임으로서 좋은맛을 내는 크로몰리에 부식까지 안되는 스텐레스이니 이제 티탄은 큰일났습니다 ㅋㅋㅋ 그냥 티탄이라는 소재value외에는 살 이유가 사라진거죠...
SPIRIT이나 위 사진의 LIFE튜빙은 1050-1200g정도의 프래임이 나오죠... 크로몰리고 탄성이 엄청나지만 정말 가벼운무게입니다. 위의 프래임도 엠티비프래임지만 1600그람대이니 탄탄하고 잘나가는 알루미늄프래임에 비교해서 뒤지지 않는군요... 멋집니다!
So a lot of you have heard the hype about the new Reynolds 953. Well if your wondering yes I will be building with it, although it may be a fit with only a few of you. Here’s the skinny: 953 is a stainless alloy butted tube made for Reynolds by Carpenter Technologies, USA. For those of you that have been around a while you may remember Carpenter for the Aermet tubes that saw very limited application in the bicycle industry about 10 years ago due to it’s difficulty to work with. 953 will offer some of the incredible strength and weight saving properties of Aermet as well as corrosion resistance, while solving problems with fabrication.
To address the hardness issue Reynolds is offering the material in either an annealed state or in it’s hardened state. This will allow builders to use it without going to extreme measurers, but will require heat-treating after the frame is built adding costs. To give you an idea of just how strong 953 is, the average tensile strength of 4130 chromoly is about 60KSI, the strongest material we typically see use in bicycle tubes is 180 KSI and 953 is up to 290KSI!
So who is 953 right for? If you want lightness and durability titanium is probably the way to go unless you’re a die-hard steel fan. With the extremely thins wall (down to .3mm) of the 953 denting and buckling may be an issue especially if your hard on your bike but we have yet to see. Due to the cost of the material and heat-treating a 953 frame will be every bit as expensive as titanium. If you’re a person that just loves steel or wants a lugged or fillet brazed frame or just wants the polished luster of a stainless frame that is as light as steel can be, 953 is probably the choice for you.
