My 2018 Trek Emonda bare was 17.5 lbs.

As you can see, aluminum bikes do not necessary have a weight penalty. Nor are titanium bikes particularly light.

I would say that since about 2001 that most decent bikes couldn't be declared as "heavy". The complete Look KG585 which was a light climbing bike was 16 lbs even bare.


Making bikes light is one thing, making them last is another.

My last allow bike was a Specialised Allez. The frame was light enough,
about 1.5KG (3 lbs in old speak). I weighed it when I stripped it for
return, it had cracked due to fatigue. It was a thing of beauty, much
nicer than the horrid oversized carbon frame they replaced it with.

My previous alloy Trek failed at about the same distance, ~10,000 miles.

I thought the benefit of titanium was that like steel it had a fatigue
limit, meaning it wouldn't inevitably eventually fatigue like aluminium.
I know aluminium bikes can be made so the fatigue failure takes a long
time, but I suspect this adds weight. So I bought a cheap heavy gravel
type bike, it is real heavy, but surprisingly fun to ride.

Given that the CDC reports that 70.2% of U.S. adults are overweight or
obese the frantic search for a lighter bicycle seems rather futile.
