has anyone tried this? I was at a shop today and the sales guy insisted that
these are where most bent riders end eventually. It was too rainy to test ride anything. Also, is chromoly really aluminum on top of steel? I was under the impression it's an alloy yet wasn't able to verify on google |

The "Tour Easy" and "Gold Rush" models are excellent bikes all around, very easy to ride, fast, and reliable. The "EZ" line of bikes is easy to ride, inexpensive, but not exactly high end. Also, is chromoly really aluminum on top of steel? The "Tour Easy", "EZ-1 SC", "EZ-3", "EZ Sport", and "EZ tandem" models are chromolly steel. The "Gold Rush Replica", "Fold-Rush", "EZ-1 Lite", "EZ-3 AL", and "EZ Sport LE" are aluminum. And the "Ti-Rush" is titanium. None of them are "aluminum on top of steel".

Chromoly is a hi strength steel alloy thats fairly light in weight(for steel).It can be brazed. |

run, dont walk as far away from that place as you can- I've got a tour easy- I
love it and wouldnt trade it for anything (except maybe a p-38) but a bent is such an individual thing that anyone who tries to spoon you into something just cuz everyone else is doing it is talking out of orifices remotely located from his mouth. you might very well end up with an easy racer- but the only way to find out for sure is to ride as many different types of bents as you can get your hands on gebuh sid wrote: has anyone tried this?

For what it is worth, chromoly is a 4130 steel alloy which is widely used
for stock car racing and airplane frames. It is a high-strength and easily weldable alloy. This is one of the reasons it is a logical, inexpensive choice for bicycle frames. In my opinion it is a better choice than aluminum from the fatigue standpoint. Portions of aluminum frames that see high cyclic stresses need to be beefed up relative to steel. This is why in many instances aluminum frames will appear fatter than their steel counterparts. "sid" wrote in message news:81e_b.8836$CQ6.5031@fed1read05... has anyone tried this?

Forgive me for getting carried away, but I just had to respond thoroughly to this response: First a response to the original poster: Test ride lots of bikes of various configurations, and buy one you like and can afford. It is most likely that factors like the seat height, steering arrangement, or even the number of water bottle braze-ons will make much more difference to your long term enjoyment of the bike than the exact metallic composition of the frame. As for the dealer who suggested the Easy-Racers bikes, I'd tell him that most everyone eventually ends up in a pine box someday, but that I'm not going to make my current choice of sleeping arrangements based on that fact. Even if what he told you about most recumbent riders eventually finding themselves on Easy-Racers were true, an Easy-Racer bike may not be the right choice for you right now. They are indeed nice bikes, but they are not for everyone. Now a response to "Samuel Burkeen" : Actually, 4130 is just one type of chromium-molybdenum alloyed steel. The 4 means that the iron is alloyed with primarily molybdenum, the 1 essentially means that there is no more than 1.5% non-ferrous metals in the alloy, and the 30 means that the steel contains 0.30% carbon, which is a low enough carbon content to make the steel easily weldable. 4140, and 4340 are other common chromium and molybdenum alloys, but they are not as easily weldable is 4130. 4130 is widely used by experimental aircraft fabricators, and industrially it is used primarily in high-temperature applications. NASCAR, if I am correctly informed, mandates that mild steel be used to construct stock-car frames. Mild steel is non-alloyed low carbon steel (1018, or 1020). The reasoning behind this mandate is that these weaker steels are more likely to absorb impacts by deforming than 4130, which is more likely to break than is mild steel. Crash protection usually isn't an issue in bicycle frame design. If I understand correctly, NASCAR allows the use of chromium molybdenum steel in non-structural components. Aluminum, and its alloys, certainly does not have the same fatigue resistance that steel has, but the reason that aluminum bicycles usually have fatter tubes than steel bicycles is manifold. For a given cross-sectional area, aluminum is not as strong, speaking of tensile and compressive strength, as steel, but it does have a lower density. To make aluminum tubes as strong as steel tubes they have to have more cross-sectional area than steel tubes, i.e thicker walls for the same outside diameter, or bigger diameters for the same wall thickness. For a given weight, larger diameter tubes are stiffer, i.e. more resistant to bending, than smaller diameter tubes, but with equal tensile and compressive strengths. Without showing the math, suffice it to say that, for a given tensile strength, aluminum tubes can be made stiffer than steel tubes while maintaining walls thick enough to discourage buckling or denting, which is a problem with very thin-walled steel tubes. On the other hand, the high strength aluminum alloys, the 6xxx and 7xxx series alloys primarily, get very soft when welded and are a pain in the anal orifice to post weld heat treat and age properly in order to restore the original properties of the alloy. However, almost all small manufacturers get away with not performing a post weld heat treatment on their ChroMoly frames. I hope this helps someone, and if I'm in error any where here, then I apologize, and ask that someone who actually knows what they are talking about, i.e. not me, point it out. I'm always eager to learn. "Samuel Burkeen" writes: For what it is worth, chromoly is a 4130 steel alloy which is widely used for stock car racing and airplane frames.
