costum build?

I believe the Moots Smoothie (http://www.moots.com/bike-mtn-smoothie.php) is made largely of 6-4, and they can definitely do custom builds.

I like ti bikes but I really don't see the benefit of ti over good aluminum when it will be a fs bike. Unless you have extra cash you have to get rid of. :rolleyes:

Moots uses standard ti on their mtb. Closest would be Litespeed with 6/4 downtube.

No one with series offroad intentions would go full ti. Can you say noodle. Front triangle OK, but the rear would have to be al for stiffness.

But like Ken said, stick with aluminum. It's lighter & stiffer and you can get some really nice stuff.

i am not a mtb but why not full ti 6/4
mechanicly its much stronger and stiffer then alu
so how can alu be stronger sorry do not get this
you can get stiff in the rear and also have suspension!

i remember when i was at gregs LeMonds house he had a nice ti mtb frame build
i saw one that came in out of 6/4 titan
i would not go any lower then that
also a aerospace certification for the titan material

You need to understand the mechanical properties of each metal and then you will understand the strength and weakness of each.

But better yet, do what I do and test a number of different bikes.

cees-pal, shouldn't you be spending your time helping N-A-S-A figure out how to fix that "falling foam" thingy?

You may find this series of articles about materials by Scot Nichol (Ibis Cycles Fame) interesting.

If you ask John Castellano(Bow-Ti and Silk Ti designer) really nicely, he might be able to help you out, or point you in the right direction

You may also want to talk to Titus Ti in Arizona

Ticycles might be of help

Finally, www.ifbikes.

I know most of these guys don't work in 6/4 Ti, but I bet if you talk to them, they'll explain why and maybe make you change your mind.

Good luck.

not a complete frame in 6/4 but some tubes

I've been riding a Moots Smoothie Ti since it came out. Nothing noodly about it. Intellectually I agree that there is no real good reason to go Ti if going full suspension. When we added another Smootie to the house (for wife), we went Al. But like many on this board who spend considerable coin for the latest/greatest/lightest/fastest/newest/etc. I just had to have it. No regrets, it's a great bike. Like my road bikes, it's more than I deserve and more than my meager abilities warrant.

For the really exotic, go with the Titus ExoGrid (Ti/cf) Racer X. Titus took a great al mountain bike and built it in Ti with diamond shape cf inserts.

Jeff Jones makes some amazing custom mountain bikes out of Ti (like the vertically compliant hardtail in the mtbr posting):

You probably could find someone to build a 6-4 frame for you but why would you want one? The tubing offers no real advantages over standard titanium or aluminum and would be extremely expensive.

well standard titan is not so strong as 6/4 if you look at the mechanic properties
and its not more expensive that what people let you beleive only the aerospace certification cost a bunch
if its standard or 6/4 titanium
it has a lot advantage over alu
i just name one in salt water you do not have problems of corrossion
unless you annodise alu but that with every metal when you give a protective layer
and the creep is much better
just name one

Tomac/Litespeed produced a full titanium frame with a 6/4 titanium downtube. Here's a link to a review.
http://www.mountainbike.com/bikes/article/1,4823,7375_601,00.html
The high cost of production led to a $3,500 list price for the frame and consequently not many were sold. If you're are interested in one or want to see some photos check out Ebay where Pre-owned Bikes is selling new frames at considerably reduced prices.

I would strongly encourage you to talk to Titus. Titus builds many custom TI FS bikes (titusti.com). The thing is they also build production alumimium FS bikes. Titus will tell you Aluminium makes for a better FS bike and there is no reason to go TI unless you need custom geometry.

This is direct from their Racer-x page:

"Q: Why would I choose Titanium or Exogrid over Aluminum?
A: We offer the Racer-X in Titanium, Exogrid and Aluminum for a variety of reasons. The Titanium and Exogrid frames are built as a fully custom framesets, to your particular dimensions and needs. If you need more stand-over clearance and a longer top tube, then Titanium or Exogrid are for you. If you want the bike designed for a longer travel fork, we can do that too. Basically, If you have a special need, prefer the durability of the brushed Titanium finish, or simply want the trickest bike made, then the Titanium or Exogrid may be the way to go. On the other hand, the Aluminum frame comes in eight sizes and ten colors. It weighs approximately two ounces less than the Titanium version and about the same as Exogrid. If one of our stock sizes fits then the Aluminum frame is a great choice. Also, If you like your bikes a little more colorful, you are a gram counter or you are trying to fit within a budget, then the Aluminum frame is the way to go. Both The Titanium and Aluminum frames have equal stiffness and will ride identically. The Exogrid Frame sets a new standard for technology and frame stiffness. Visit our Exogrid page to get the full scoop!"

that the Ti Smoothie was on the way out. Ti Boy rides his about once a year so it stays shiny and new. Too bad, I think it is a better bike than the new Cinco. But Ti as a MB is a little crazy. There is no weight advantage and it trashes just as easily as aluminum. Fortunately Ti Boy has a habit of landing on his head so no damage there.

I ride a Fango. It is 1/3 the price of a YBB and weighs the same. I feel the same way about MBs as racers feel about Crit bikes-Don't over invest! As it is with frame only bikes it is a small fortune to build it anyway. I can (have) more easily see the purchase of Ti roadbikes which are not use to jump logs and get through rock gardens, that killing a Moots, Dean or Serotta MB at Waywayanda here in NJ.

Ada,
Their is zero chance that you could tell the difference in the ride of 6/4 vs. 3/2.5. The air in the tires makes so much more difference than anything else.

Most importantly, why would you want to ride an inferior hard tail around when you could ride something nice like a TURNER. If you live in a flat state, it doesn't matter much. But, if you live anywhere with some elevation and interesting terrain you owe it to yourself to get a decent bike.
Riding a hard tail is as foolish as using V brakes. The Gods of technology have spoke and they like full suspension and disc brakes.

Cheers,

Kane



i am not a mtb but why not full ti 6/4
mechanicly its much stronger and stiffer then alu
so how can alu be stronger sorry do not get this
you can get stiff in the rear and also have suspension!

i remember when i was at gregs LeMonds house he had a nice ti mtb frame build
i saw one that came in out of 6/4 titan
i would not go any lower then that
also a aerospace certification for the titan material

well that with all bike's can you tell the differance when you ride between a alu 7075 or a 6020 or a 2024
no !!!
so i have certain mechanic reasons why i want 6/4 titan
