"Ti flexes too much", are you sure?? My Van Nicholas is definitely a stiffer frame compared to my CAAD 9 (aluminium frame). And my Look 695 (carbon) would definitely be the stiffest frame I've ever owned. I don’t have any say on steel frames, but a mate of mine said that it has similar characteristic as the steel frame, just much lighter. I guess stiffness is all relative to the composition of the alloy/material, the tubing, geometry and construction method.
IIRC, tube stiffness is proportional to the diameter ^ 4, so all one needs is to make the tube ~20% larger diameter to match the stiffness of a steel tube. Because Ti has what, half the density of steel, you can leave the wall thickness as-is so that the larger tube still resists dings while still being lighter overall. Pretty cool.
Yea did you notice he didn't touch a part of the frame that's going to be welded....so no big deal! I also have had bikes made of all 4 materials and they all have their own characteristics, good and bad. Ti and steel have similar characteristics with Ti being much lighter but steel stiffer at the BB. Both having that magic carpet ride (Reynolds 531 coming to mind). Al is stiff and can be rather harsh riding but very stable on descents due to it's stiffness. Carbon (2) cracks at the BB!
Titanium is bomb-proof so far as corrosion and such. Maybe a little heavier than aluminum (depending on the manufacturer). The biggest difference is cost.
Depends on the part and the purpose. I'd rather have a Ti frame because as long as Ti is flexed under its deformation limit, it will not fatigue and crack, while Al will. Also, to get Al tubes strong enough to resist dings, the tube has to be so darn stiff you risk getting the bone-jarring ride of early 'pop can' Cannondales. There are good Al bikes, e.g. Spooky and Gaulzetti to name a few, but the "Ti ride" mystique is well-earned. Now, for things like headsets and cranks, Al makes a lot more sense. One can make them in Ti, but there is no practical benefit for headsets (whose parts are cheap and essentially consumables that last a long time anyway), and hard-to-afford for cranks. Cane Creek's eeCranks are amazing, but $1k.
Matap..BIKE nya 👍👍👍
So cool!
Fascinating
Nice

Forgot to mention, aluminum tends to have a 'rougher' ride. Not much cushioning.

Will Moots ever consider making steel frames again?? the market exists.

which is better titanium or alumunium?

What is up with the shaky camera? It's making me dizzy
Titanium bikes are for old guys. They are basically just a comfort bike and can't match a good racing bike.
+Charles Rush Blame the bike!
That's truly the dumbest comment in this thread.
