Litespeed t1 review - workable solutions
Are Litespeed bikes any good?
Alongside speed, the Ultimate Gravel has a quintessential titanium ride quality. The sound it makes against the tarmac – that gentle zing – and smooth handling both left a distinct impression on me. For all that, though, this is a bike that just begs to be taken off-road.27 нояб. 2019 г.
(Collisions Echo) - We looked at the myths surrounding carbon fiber. We lifted the lid on aluminum. We have investigated whether steel is actually real; it was.
But there is still a huge void in the GCN Materials Science course. And that's titanium. For a while, in the early 90s, titanium was the next big thing.
And to be fair, it was short, but gradually it was dwarfed by carbon fiber. Even so, it still has a legion of super loyal fans, and rightly so. So if you are not on board the titanium suit yet, or perhaps more precisely military aircraft or submarine, what do you need to know? (relaxed chill music) Although it has a reputation for being the reservation of the Russian or American military, which it was in fairness, titanium is actually the ninth most abundant element in the earth's crust.
And in addition to being used to make bicycles, it can be found in sunscreen and paper to make it whiter. What makes paper white doesn't really help much in making bicycles, however, other than maybe drawing your first ideas on, and that's because it is titanium oxide that is used in paper, while when we make bicycles we need one Titanium alloy. While the very first titanium wheels were made of pure titanium, they were very flexible and they weren't very good.
And it wasn't until a titanium alloy called 3AL / 2.5V became that that changed after 3% aluminum and 2.5% vanadium were mixed.
The other popular titanium alloy for bicycles is 6AL / 4V. Both have a very high Young's modulus, which is a measure of the stiffness of the material, so they have a gPA of around 110 as opposed to, say, 6061 aluminum, which has a GPa of around 69. And they also have a much higher yield strength, so that's where a material won't return to its original position when tension is removed.
So six-four titanium has a MPa of 1000 while 6061 aluminum only has a MPa of 270. And that means that the material does not deform, bend or kink in the event of a crash. Three two-five actually has a lower yield strength than six-four titanium, but that's one of the reasons it's used almost exclusively and is widely used in bicycle construction because six-four titanium is incredibly difficult to machine.
It's more brittle and less ductile, so it's incredibly difficult to shape into simple shapes such as pipes, to start with, in fact, most six to four titanium pipes are rolled from sheet metal and then welded, while three to 2.5 tend to be are seamless. This actually makes a more consistent overall pipe and is therefore better from a quality control point of view.
In other words, while Six-Four-Titanium's material properties might look better on paper, it won't necessarily make a better bike. Titanium is known to be super light, but in fact, as a material, it's 60% denser than aluminum, considering what we've just heard about the other material properties, you can still see why titanium frames tend to be a bit lighter than aluminum frames. So the best examples would be around 1000 grams for a titanium frame and around 1100 grams for aluminum.
So 100 grams in there. And the reason the difference is actually still quite small is probably because of how much easier it is to machine and manipulate aluminum, and we'll get to that a little later. And we have to keep that in mind.
Because of this additional density, super-light titanium frames also have extremely thin-walled tubes. And if we compare it to steel, titanium is just as strong, but 45% less dense. That explains why titanium frames are significantly lighter than steel.
The toughness in relation to the material properties makes processing titanium very difficult, as we have already mentioned. Fortunately, however, many of these difficulties are resolved by the pipe manufacturers themselves. One of those things is that internally butted tubes cannot be safely made from titanium.
Basically, there is a risk that titanium can be overloaded, which would then lead to a weakness in the material. On the other hand, you can bump the pipes on the outside, so it is better to let them go. If a mandrel is machined in the pipe, titanium is scraped off from the outside.
But that depends primarily on the straightness of the pipe, because any imperfections would then also be reflected in the wall thickness. So probably that's why this bike behind me (tap frame) is made of titanium tubes with a straight diameter. Titanium is also slightly more difficult to weld than steel or aluminum, and that is because at higher temperatures it reacts to oxygen in the absence of this gas.
To be fair, all metals must be welded in an inert gas environment, but titanium is especially delicate. To put it in context, if you are welding steel, an acceptable purge, so called, needs to be around 1000 parts per million of oxygen, while for titanium it is only 10 parts per million. So this is a bit of a challenge for a welder, and if oxygen gets into the weld, the titanium will oxidize if you stick to f. remember rom earlier in the article is a very white, almost worthless white powder.
The technique then is to weld in an inert argon atmosphere, so basically you run argon gas into the pipes and then externally into the weld, but then that ensures that everything is nice and strong. The last thing that Titan can make a bit difficult is work. You see, we mentioned earlier that aluminum can be molded and machined into all sorts of intricate shapes, but titanium can even bend a simple S-bend chainstay.For example, extreme caution is required not to rework the material, which then does can cause it to become brittle and thus weak.
To avoid this, the titanium has to be annealed, heated there and then allowed to cool slowly between each incremental step of the process. It's quite time consuming, labor intensive, and it's another reason titanium bikes are quite expensive. Is it expensive? Well compared to aluminum bicycles.
But it's probably bly on a part made with custom steel, and significantly cheaper, it has to be said, than high quality carbon fiber. It's a boutique material, and yes, there are boutique costs of $ 10 and $ 12 a kilo as well. Finished pipes cost between $ 100 and $ 120 per kilo.
But that makes it a bit more than standard steel and on par with stainless steel. But I dare say it, and because it might not be quite as fashionable right now, there are some relative bargains to be found in the cycling world. And to be fair, we've given you an incredible amount of information so far, but we still don't fully understand why Titan has such a loyal following, and frankly, it can be so great.
You can get a custom-made titanium frame very easily and it will be considerably lighter than an equivalent custom-made steel frame, i.e. about 400 grams lighter.
I would guess an average custom-made steel frame weighs around 1,600 grams; Titanium could be around 1200 grams. Which is pretty important if you want to build a super light road bike; yes titanium is reactive, but your frame won't corrode, not like steel, not like aluminum; it will take. And so the Ti-Bike is the keeper for many people.
Beauty is very much in the eye of the beholder, but I think there is undeniably something special about titanium. I mean, look at the raw finish; it is as if it is glowing. Ah, the ride quality, even more difficult to determine than the aesthetics.
Now Titan traditionally has a driving experience like no other. But the boundaries between the materials are blurring; Engineering brings things to new places. So steel can now be as stiff as aluminum; aluminum can now be as forgiving as carbon fiber.
But titanium has traditionally been about zing the road, and that sounds pretty amazing to me. Now, unfortunately, I've literally never really spent any time on a titanium bike. So I hope to find a remedy sometime soon.
Well there is your Titanium 101. Hopefully by now you can add it as a material that you know as well as steel, aluminum and carbon fiber. Please give this article a big thumbs up.
If nothing else, you've got yourself into Have seen some bike porn in the past few minutes, and if you want to see any of these articles update your knowledge of the other materials, why not check out the one about aluminum down there.

Bottom Line: LiteSpeed Web Server is the clear winner in the battle of the software web server solutions.24 июн. 2020 г.
Is 26 pounds heavy for a road bike?
Roughly 20 pounds, or 9 kilograms. The cheaper the road bike, the heavier it will be. On the lowest of the low end (<0), a bike that's over 25 lbs is heavy, but most of them fall pretty close to that. Mid-range bikes (0–1200) should be under 21 lbs.
Is titanium bike better than carbon?
Titanium is highly flexible, so it offers better shock absorption than carbon fiber. Carbon, on the other hand, doesn't deform under load linearly. The lack of deformity aspect on carbon means that it generates a harder impact, consequently a harsher ride.4 нояб. 2020 г.
How long does a titanium bike last?
Carbon and titanium bike frames will last the longest with proper care, with some even outlasting their riders. Aluminum and steel bike frames should easily last 6 years but will require regular maintenance to keep them running any longer than 10 years.
Is the Litespeed t1sl a good bike?
Although it may lack the machined-out-of-bedrock feel that the top carbon race bikes posses, the T1sl’s BB stiffness has to be within the top 10 percent of all the road bikes I’ve ridden, and that’s pretty good for any bike, much less one of the lightest titanium frames currently on the market.
Where is The headbadge on a Litespeed t1sl?
The T1sl’s headbadge is kind of like a mullet: business in the front, with a headbadge engraved onto the tube in-house; and a party in the back, with an actual badge mounted on the seat tube.
Which is the lightest titanium frame from Litespeed?
Litespeed already make the lightest titanium frame with the Ghisallo, which clocks in at an unbelievable 770g for the medium-sized chassis. The Archon is designed with more than scales in mind though and just looking at the frame it’s obvious power transfer is at a premium.
