Titanium

Is titanium practical for BMXing (all types) I was arguing with my friend and he's saying that using titanium on Freestyle and such would be stupid because it would just snap before it brakes (he knows nothing about BMX) and would really be a stupid idea... I think he's just talking out of his A$$, but I came to people that actally know... So is titanium really good in Freestyle, Flatland, Racing, etc..... Please use actual factual information or experiences, not just opinion...

It's not practical for welded parts, but it's a good material for axles and spindles.

Yes, because it's insanely expensive and it isn't as durable as chromoly. For racing, sure, it'd probably be fine, but for trails, park, street, or even flatland, it wouldn't last long.

Ti just isn't durable enough to withstand street. There is a new flatland frame made out of Ti - it's over $1,000.00US for the frame only. It is awesome if you have that money for a frame, but most of us bmx riders don't. Like aluminum, Ti really just doesn't make sense. You can use a solid piece of Ti, it'll be way lighter than steel, but it won't hold up and will cost a ton of money. Steel (chromoly) is simply the best metal to use on most parts of your bike.

Now, some stuff can go to Ti and probably save some ounces at a high cost. Brake levers, brake calipers, cranks?... Spokes... seat clamps. Sprockets.

Basically, non-impact items. Spindles and cranks are iffy because of the abuse they take. Axles definitely NOT if you ride street/grind at all.

Brake levers and arms are generally made of aluminum, which is lighter than ti, so I don't see how much could be done there.

Are you positive? I am 99% sure Ti is ligher. Or it could be made thinner to provide more strength. The RNC Ti Lite sprocket is as light (or lighter?) than aluminum and provides more strength.

i was under the impression that ti was stronger than 4130, and slightly lighter. but, on frames, it's even lighter because,as it's stronger, not so much is needed. it is expensive though. on the axles/spindles discussion, profile racing make a lot of ti stuff with lifetime guarantees against bending and snapping, and they certainly wouldnt give a guarantee like that to products that they thought would break now, would they?

Given its ride qualities, titanium would be the ultimate frame material for freestyling. However, the cost to manufacture frames would put the price through the roof (as seen by the afforementioned Ares frame). It is lighter than steel, and it will resist breaking a ton better than any other frame material, except for carbon fiber. But carbon is pointless for freestyle because of its properties.

You can use thicker tubes on a Ti frame which will make it both stiffer and stronger than 4130, but it would still be lighter thanks to the fact that its specific gravity is about half of 4130's.

Yeah, i know what you meant, I just forgot to explain myself in my last post why it is better than steel. Your quote was completely true.

It is lighter than 4130, but it's not all that great for freestyle; look at the photos of what happened to Taj's titanium Barcode on Google or something. It's great for non-welded parts, though (ex: sprockets, axles, spindles, cassette drivers).

Yeah, I suppose that that would be true. Although I can't really imagine myself doing a sprocket grind on the RNC Lite sprocket.

They have a couple of RNC sprockets out there. The really lite one and a design that is more street oriented. I ride flatland, so I am ALL about aluminum and Ti. I am very seriously considering getting the Ti Choise frame.

I would ride Ti on street. I would use brake levers, sprockets, and MAYBE a 3-piece crank spindle. But, not pegs or other stuff I was going to be tearing into. 4130 or better yet, heat treated 4140 is the way to go with stuff that you are gonna be particularly harsh to.

Chrome plating or Duralectric plating is the way to go for braking surfaces. Aluminum sucks, ti would likely not be very good either.

okee doke... do you know why chrome makes for a better braking surface? on another note, I talked with the guy you referred me to BMXTRIX, and he's sending me a couple of pairs of brake posts for free, because he's so nice. thanks...

So the Airborne Ti frame is for race only, huh? How much abuse could Ti take?
