A salesman told me that the frame titanium is very very very lighter than the aluminum frame, dnd heavier than carbon. So what's the advantage of the frame titanium cause the its price is very high?

What are the advantages of a frame in titanium?

It's a difficult material to work with, not really much lighter, but look stunning & supposed to last forever if you buy a good one.
Looks alone would just about sell one to me-if I could afford one!Posted 1 year ago # -
Ti (if designed and built correctly) has an almost unlimited fatigue life.

makes your wallet lighter that is for sure

It's a lovely shiny metal. That does it for me
Good for a mtb frame - no loss of finish with rough use - and you can sort out any scratches etc with a bit of polishing.

You have absolutely no corrosion issues to worry about and there's no paint to scratch.
They do make a horrendous noise when they crack though!

The advantage is that you will always have a top end bike.
Because when it snaps, you wouldn't dream of going back to a lesser model, you would just bite the bullet and get another fancy one.
A 5 year old Cotic Soul rides much the same as a new Soda.

it makes this frame possible... no pivots to be found, relies on the 'almost unlimited fatigue life' mentioned above to engineer specific flex into the frame to give up to 5" of rear travel...
Oh, and the finish always looks superb, and the welding/finish on the frames is almost always a thing of beauty!
any excuse to show off my lovely, any excuse I tell you!

It usually has a "ti" feel that many love.
It's not all about weight.

As light as aluminium, but as strong as steel and they look nice when polished up.
The bike for life card is overplayed though. Even if it doesn't break, it will become dated or most people will get bored of it after they've had it a considerable amount of time.

Because people will drool.
For me, feel of steel at almost half the weight.

Feel of steel?
After swapping from my switchback to a 456 I've decided on a few things
1, stiffness is good
2, 'most people' who cliam to like the feel of steel have a 456 as they're cheep and abundant
3, the 456 is 'effin stiff (compared to the switchback with identical builds, even the tyres were the same, i just swaped everything over, adjusted the mech and brakes and was away apart from swapping a titec knock seatpost for the thompson one)Therefore 'most people' are wrong!
Would I buy a Ti frame? Maybe, it would have to be something very special to warrent spending that much cash. Especialy when as Mike said, you'll be bored in 5 years anyway, maybe not even riding bikes anymore, and costing double what the lighter carbon frames do (which may well have a 5 year or even lifetime warrenty itself) it would need to last 10+ years to be even aproaching VFM.

The salesman if full of it, that much is clear.
You can get very light frames made of all those materials, Ti does keep its looks thats for sure, but it not infaliable, as shown by the broken one.
I had one and I loved it, but I did think the BB wanged (flex) about a bit.
It was incidentally the exact same weight as the identically designed and sized Ally frame that came after it, and something similar is in carbon would have been pretty close weight wise.Posted 1 year ago # -
A carefully built Ti frame is a thing of beauty, a cheap Ti frame is just a shit as the next bike. Geometry first, material second.

I thought Ti wasn't as light as alloy, or as strong as steel, but had a better strength to weight ratio than either of them.
I could be talking out of my rrrrs, so please feel free to blind me with science!

really? i would rather have high quality steel than a chinese/russian/XAD frame. i wouldn't call those "top end"
the bike for life thing is just a myth. they break and fatigue just like other bikes only they cost more to repair.
Posted 1 year ago # -
Ti has a comparable modulous to steel (so is as stiff)
And a comparable density to aluminium (so as light)
So in theory you could build a frame as light as the aluminium version and as compliant/wobbly as the steel version. But things like hydroforming make the analogy redundant as nowadays a steel frame looks different because it used small diameter round tubes compared to the larger aluminium ones.

PP, I cant blind you with science, but I had an 18" Tinbred and now have an 18" Scandal, considering the different materials you couldnt get 2 closer type/style and geometry bikes, they both hit the same scales at 3.5lbs...

By high quality steel do you mean 'made form 853 in a shed after being designed on the back of an envelope and costing 6x the price of the mass produced 520/4130 equivalent from tiawan which is all but identical'?
Nothing wrong with stuff from the far east and Russia, global frames were from Russia, airborne then later Van Nicolas were made in China, the next lot of 456's will be Chinese!*
*all IIRC

Yep. But they would have had different size/wall thiknesses of tubing, so there could have been more VOLUME of alloy, so the smaller volume of Ti would have been denser and therefore heavier?

I dont know what to say to that!!!
Posted 1 year ago # -
Yup from an engineering perspective it's the ratio of stiffness to density that's desireable, it's neither stiffer than steel, or lighter than aluminium!

Al 2.7 g/cm3, 2.8 moh - lightest/g but softest
Ti 4.5 g/cm3, 6 moh - not as light/g but hardest
Fe 7.87 g/cm3, 4 moh - heaviest/g and not as hardPosted 1 year ago # -
A 5 year old Cotic Soul rides much the same as a new Soda.
My experience (not of Soul and Soda but Swift and Pegasus) makes me truly believe otherwise. Both having the exact same geometry, it is quite amazing how much nicer the Ti feels to ride than the steel bike. And it's about a lot more than 'just' the weight difference.

What does Jesus sorry Cy from Cotic ride? Answer: a Soul
I think you'll find he rides all his frames at one time or another, as do I. He has a young family, I don't, so I justify myself having a Ti frame. If I were a bit more financially prudent perhaps I wouldn't....

Ti haz more awesomness
Posted 1 year ago # -
Cos when you turn up at a race, surrounded by generic alu and carbon bikes, the one everyone wants to look at is the Ti one. Technically speaking, it "haz more awesomness"

Ti haz more awesomness
Probably truest of all the coments so far!
Dirt (i think) had a charge duster Ti and steel painted and built up identicaly, they then let a load of riders test them over a period of months, occasionaly telling them that they were the same, somethignes feeding a red herring (this one is slacker, lighter, smaller tubes etc) and reversing the same red herrings (so one person is told theirs is slacker, but so is the other one).
Supprisingly enough, nealry everyone agreed that the the one they were told was different was in fact different. Don't think they proved it was any better though?

coz it is spaceage / aerospace...
even if it only used for hydraulic pipework...

Just had my ultegra HT11 bb removed from my Ti cross frame it looked OK from the outside but it had disintegrated inside the frame, aluminium will always corrode when mated with Ti I had also used the correct grease when fitting the original but salt off the road soon helped the process along. Still the frame is fine and a bb fitted is only £30.

I love my Ti
I dont care if its better/lighter/stiffer/whatevers compared to whatever other material or bike
Its my bike I love riding it and thats all that matters to me
In 18 months I still grin when I get a leg over (oo-er)Posted 1 year ago # -
My 456Ti is more composed at higher speeds than the steel 456 it replaced, which was comfier at slower speeds.
Not science, just feel.
