I was just wondering if anyone knew of a company other then like SRP who made titanium bolts, or titanium hardware just for BMX or what not, I look but I only see SRP. Thanks.

The aforementioned, and RNC (http://www.rncmfg.com) and 43 Bolts (http://www.43bolts.com).

If you're actually planning on wasting cash on titanium hardware, though, you're a complete dumbass. The cost:weight loss ratio isn't even close to practical. You can get six ti bolts for your stem and save maybe a quarter-ounce at the most, but it's going to run you at least forty bucks.

edit: On a sidenote, that price will be increasing even more, because - as a friend who is sponsored by Knight has informed me - Boeing has bought up a large percent of the supply of aircraft-grade titanium, so the market value has apparently skyrocketed.

Actually it's 1.3 ounces. !!!!! Now it's worth it! For all you mart people out there, I am joking. It's not worth it.

why do people buy all this titanium and light wieght stuff and pay mega bucks just to save a few ounces.

For the same reason people rollerblade.

Ahem! Titanium may be stupid for BMX, but not for other kinds of bikes, thank you.

I used to have a Titanium BMX frame, way back in the '80s. It was a Thrasher. Damn, I miss that bike! lol

When your paying wholesale for Titanium, it is worth it. Titanium has its place everywhere.

I'd like a Ti coffee cup........ Imagine how much more work I could get done if I could lift my coffee cup faster? Wait a sec, is Ti lighter than ceramic? What are the insulating properties? Or better yet, some Area 51 top secret material. Perhaps those form "out there' have a nice Ti substitute. :)

Area 51, Cydonia, Conspiracies, bigfoot etc. While your taking a break from BMX, check out these "interesting" sites. All work and child safe of course.

Ti would dissipate heat rather quickly. But you can get an USB coffee cup warmer, which would bring balance back to your world.

Ti is NOT lightweight. It's the second heaviest material commonly used in the bicycle industry, next to steel.

Density to tensile strength. Confuse the kiddies with something that actually matters.

A lot. Various mild and stainless steels; 4130, 4140, and 4150 chromoly; True Temper OX Platinum, Verus, and Supertherm (all modified from 4130); T45 carbon steel; 831 Reynolds; Columbus Nivachrome (modified from 4130, if I remember correctly); 6061, 6013, 7005, and 7075 aluminum; various grades of titanium; and, that's just off the top of my head.

The only stainless steel used in frames I *believe* at this time is Reynolds 953, there was a big deal about it at the last Interbike. BMX bikes are pretty boring...their budget for R&D and exotic materials tends to be much lower than the wallets wielded by roadies. True Temper, Reynolds and Columbus all have extensive *lines* of various chromium / molybdenum steel alloys (Columbus Nivachrome is actually alloyed with niobium, among other things), sporting various additional alloying agents and butting. Aluminum in the 6000 and 7000 series are occasionally seen in BMX (magnesium/silicon and zinc, respectively) but more exotic aluminum alloys exist in the roadie world, commonly 9000 series (zirconium) and scandium aluminum to name a few examples.

The big 3 are steel, aluminum and titanium, with carbon making up a nonmetal 4th entry. However within each category there exists HUGE variety.

Frames, yes, but - for example - Marwi uses 304 stainless for their steel spokes. I'm talking about everything from frames to sprockets, which gives a ton of different varieties of the big three to work with.

Don't forget 2000 series aluminiums, which thanks to odyssey we are starting to see more of.

T45 is strictly speaking a manganese steel, which I think was a continuation of Reynolds 531. The carbon is a given.

2000 series? For machined parts, right? I didn't think you could really weld that stuff.

It's used on the Elementary stem.

I guess that makes a kind of sense, given the nature of the alloy and the design of the stem. Interesting.
