    I have never seen any drop bar in Ti. Doubt it is even possible to bend Ti tubing with the current production equipment.

    The trouble with common sense is it is no longer common

    I'm in!

    If it's possible, I'll take one. Actually, I'll take 2!

    I too have never seen or heard of a titanium drop bar.

    Who's the manufacturer of this bar in the pic? Where is it made and of what titanium?

    If this is in fact even possible, the bar would probably cost Brant more to manufacture than
    the frames

    Truly a wealth of useless information.

    Not starting a flame-war or anything but why would you want a Ti version of a drop-bar?

    Any shock absorbing qualities would probably be masked by the extra thick tube needed to enable the bends to be put in with out crimping. The cost would be massive and for no benifit that I could see.

    A carbon one would make more sense as you could save some weight and tube the stiffness / comfort to some degree with the fibre lay-up.

    Personally I'll stick with the 30 alloy one

    That explains a few things.(that bike is sweet BTW) I maintain the cost would be prohibitive and as Alex pointed out, the weight penalty would likely be very high and negate the benefit of a ti bar.

    Different strokes for different folks, I guess.

    but at least it would be heavier than the alloy one.

    If cost isn't a concern, titanium is the most sensible material for handlebars IMHO.

    You don't have to go to thick-wall nor crimp if you're an experienced titanium tube bender. Dirt-drop style bars don't have any special material requirements over something like the Titec Hellion titanium risers. I actually located a person who could make the bars but have unfortunately lost his contact information when I upgraded to a new laptop. He's the same guy who made a set of curvey titanium cruiser bars that I have.

    A good comparison for comfort would be to compare the Moots titanium layback seatpost to a Thomson aluminum layback post. There is a dramatic difference in ride comfort and if there's any substantial weight difference I would be very surprised.

    In my experience carbon blows chunks for any aggressive off-roading (and yes I've had tons of fancy carbon stuff in addition to ti). Aluminum bars are the sweet-spot for durability/weight/cost but going to ti would add comfort and possibly increase durability over aluminum.

    Any guess on what it would cost to have something like this custom built?

    I spoke on the phone with the guy last year and he was in NorCal at the time, getting ready for a trip over to Japan. I was supposed to contact him three weeks later when he'd be back from Japan, but lost all his information along with all the leads that led me to tracking him down. If I remember right, the estimated cost was something like $350 for a single set of bars.

    I don't have my camera handy but I'll post photos of the cruiser bars later on today if I get a chance.

    if you have tooling like brant from on.one thers a chance you could use the same, and heat the titanium tube. IF this is the case it would be around 3 X raw stock

    Thanks. I'd be interested to see it. That TI fixed is stunning, to say the least.

    Black Sheep Bikes already makes Ti moustache bars for $175. I wonder if they would do a dirt drop. . .

    Cool! I've been sort of out of it and didn't know about this. I just checked out the website and saw the bars... and although that's a nice start I'd definitely like to see more gradual, continuous curves like the Passoni ti drop bars (which they were making in 1989!!!).

    I had the same thoughts about the bends. I wonder if that is by design or a function of whatever bending mechanism they are using. From what I have seen of their frames, it seems like they can do more gradual bends.

    OK, my bad and I should know better (Degree in metallurgy and all that!) I'll blame the post-work beers!

    Still not sure that the small benifits would be worth the extra $$ / hassle...for me anyway.

    I'm in.

    Better shock absorption, but most of all far better strength and fatigue life.

    There goes the (admittedly small but nevertheless potentially deadly) chance of breaking a bar off in the middle of a nasty downhill run.

    At least with ti it'd bend first and give you the chance to ride it out.

    I'm in-let's get some ordered!

    Unfortunately...

    Ti is super expensive right now. Not sure about tubing, but I priced some bar stock for a student's school project, and they wanted $100/lb! I wish I had the money to afford some Ti bits, but for now I'll just drool over Terminaut's Ti collection.

    BTW Terminaut, what do you do for a living, cuz I am obviously in the wrong profession!

    The Midge weighs something around 240g, so at $100/lb. it would not be expensive. Of course, tubing is significantly more expensive -- I'd guess at least $50/ft. for what you would need, and at least 3' per bar. Still, people pay a lot more for things that aren't near as durable. Peace of mind is worth a lot to me.

    Here are my ti cruiser bars next to the steel bars that were on my Merlin in scorcher mode. I'm probably going to chop off a couple inches from the ends of the ti bars and replace the steel jobbers.

    Yup. I actually have a few pieces of ill-fated CP ti bike stuff, including a Teledyne Titan frame and two forks.

    Kind of generalizing, aren't you? It all depends on the wall thickness, tube diameter, quality of Ti, etc. And compared to what type of Aluminum?

    yes it does but you can compare Titanium Ti-3Al-2.5V, "alpha" to aluminum Aluminum 7005-W whitch are prety mutch standart i the bike industry.

    James at Black Sheep made these.They are closer IMO to a Mungo than a Midge,but still offer more drop then any other Ti bars I have seen with the exception of the Passoni pictured earlier in this thread.I asked him if he could make something like a Midge,he said that the closest he can get to making one with his equipment is the one in these pics.Still the koolest Ti bars on the market today with no welds!

    Sweet curves. For a dirt-drop style I'd want a lot less flare but I'm sure that can be done?

    I think that less flare involves bending the tube more during production,I believe that it`s doable.Ask James www.blacksheepbikes.com

    Titanuim is actually denser/heavier than aluminum.
