Titanium bottom brackets?

Any benefits other than weight?

erm..........nope,

You can make friends with Corny's frame?

what's corny's frame made of?

Corn?

Murt, I don't know for sure, which is why I'm asking; isn't Ti just slightly stronger per weight/mass, therefore deflection/deformation under load might be microns less than alu and the best cro-mo? So in design, it should create a stiffer casing. Otherwise, its basically money for old rope right? Or have I spazd again?

yeah...and???
it also flexes alot, but where it is being used, it's not very beneficial (fuck me thats my biggest word to date) over steel.
oh, and it won't rust :)

only one of these statements is true. i'm not sure which, but i still think a titanium BB is a waste of money and titanium.

i heard it squeaks and flexes, no personal experience though.
i think i'd rather spend the extra £££ elsewhere on my bike tbh...

titanium gives u advantage when used in larger parts where a lot of flexing is expected e.g plane wings... BB is only what, say 6 inches or something so the flex is irrelevant IMO.
Basically there is no flex.

Advantage only is no rust, but disadvantage is that titanium is softer, therefore threads more susceptible to shearing.

Titanium = dubious in small stuff.

Steel is strong, alluminium is light, titanium is a compromise between to two (but by no means equidistant).

Unlike other bike applications you can't really use alluminium for a BB spindle (although they exist, I should know I own a few!) so titanium is the lightweight choice whilst still being robust enough for regular use.

They do flex more than steel, but if Tour de France riders (and winners) ride them then, at the least, they are viable as performance parts (performance parts here implies weight limits, good maintenance, installation with torque wrenches etc etc).

I have a titanium Tune AC38 for sale if interested, although super light and pretty strong (two sets of bearings on the drive side !) it is a bit wide for fixed/ss at 111mm.

corrosion resistance
ie. doesnt rust like steel

iso???

iso???

Pretty sure it will be a JIS . . . . need to check (EDIT: just checked it's JIS) Looks like this, but it is the newer model with titanium stretch bolts you can see here and ceramic bearings (!!).

bitch, slut, stupid JIS

This thing is so good, so light, it is worth a 6 degree, grinding, noisy, chainring destroying, cog eating chain line.

I've got a Ti Phil BB on my Affinity. No complaints.
I've also got a 15 Shimano BB on my Surly which seems to need replacing every 5-6 months and flexes noticably more.
