Aluminium doesn't corrode...steel does eventually? I think...!

allu corrodes and only gets worse and a lick of paint doesn't stop it, it just continues under the paint steel doesn't also steel just bends and dents rather than cracking so easily

I would imagine it could have a cheesegrater effect on your thighs though.

Well, my thighs anyway.

just wear through shorts very quickly!

Pure aluminium doesn't corrode but aluminium alloys can due to the other metals included in the mix. 7005 is worst. 6061 is much more corrosion resistant. (According to the info I've had through my aviation interests.)

steel is real

corrosion is ally/ally alloy's destiny!

Steel does corrode.

Never seen any rust particles on my Columbus SLX NEW steel bike frame and its 25 years old

Though my 6061 aluminum bike frame started corroding within 3 years, long since scap/recycled, though my A6N aluminum bike frame shows no signs of corrosion after 5 years

Rust bugs have evolved through time as their proliferation and food source has changed.

Have you looked at Spa Cycles Ti tourer?

Bit of muc-off, spray with GT85 and she'll be right as rain.

When I read threads like this I wonder what you guys use your bikes for. When I were a lad I made a bike from found items, some were found on the river bank some in the river - and all serviceable. It seems self evident that if it is your intention to leave your bike in your garden for twenty years then rust proofing could be a priority, if on the other hand you want a bike that offers a smooth ride then using modern materials may be the way to go.
Notice in that last sentence that I emphasized 'ride'?
Most questions regarding choice can be answered here.

don't get me wrong i am all for the modern materials eg:carbon, titanium etc etc but carbon couldn't with stand any knocks or bumps and my bank doesn't like the sound of either of those
aluminium or more commonly and alloy of aluminium corrodes easier then good steel that is well protected and isn't quite as strong as good steel or a steel alloy like cromoly
oh and i'm rather traditional in general!
Cheers Ed
oh and notice how i always said GOOD steel because there are worse/bad steels out their and then aluminium alloy might well be better but i am mainly looking at the dawes that use good steel
