    There isn't any real difference in strength between hot-rolled and cold-rolled steel, if the same alloy/grade. The difference in strength is that you are getting mild steel from the hardware store, and something stronger from the metal shop. The best reason to get cold-rolled for a seatpost is that it is more dimensionally accurate than hot-rolled.

    ...just like it is spelled...but, the kunu should be a nuku...humuhumunukunukuapua'a. I keep looking, but they tend to hold their value very well.

    Cold rolled is stronger stronger

    Schwinn Heavy Duti. Hayes mechanical disc on unknown 1 ⅛" fork. Unknown, but seamless, bars and MacNeil stem. Profile chainring, unknown cranks, Conti 2.40" tires, Araya rims with Shimano hubs front and rear. The coaster brake rear is trashed after 22miles of mostly downhill mountain biking...but still rolls pretty free.

    You are correct...I parrotted a rule of thumb that wasn't entirely accurate. Although tensile strength ranges from marginally to significantly better with cold rolled...yield strength is always significantly higher with cold rolled, which would be more important for a seat post.

    With very few exceptions... a chromoly grade is is going to be the better choice than hot/cold/as drawn mild steel.

    I'm light, 155 pounds but I always bend hot rolled 5/8 bars. Cold rolled has never failed me. Also, Allen Bonds site "clunkers" has a tip page for building klunkers and he recommends a certain grade of aluminium rod. I can't recall what it is but I use that also without bending. I have only used it in 5/8 so it should be good on larger diameter for bigger riders.

    Is that Transition bracketed by a Hank and a Fisher? I'm in awe :43:

    Yes! Lot of mods on the Hank- but I have all stock parts boxed up. It was nos when I got it about a year ago. I like riding it best of all of them. I mean of the non vintage bikes. I have 2 Transitions actually. t red.jpg trans5.jpg

    Not an oval. I have a 34, 36, and a 40 for this bike. I change out as mood/riding condition dictates. I live in Colorado so I have many different choices of great riding right out my back door.
