I once had a carbonfiber bike with an aluminum fork. How is that for backwards?

The aluminum fork flexed like a wet noodle. Apply serious front brake pressure and it chattered like you wouldn't believe. After longer than I'd care to admit, I realized that the aluminum fork just wasn't safe and got rid of it. I can't see any possible reason for using an aluminum fork.

Most, if not all, aluminum forks generally available are quite soft. As such, they offer a nice smooth ride. They are also fairly cheap which is a good thing in my book.

I have the oportunity to pick up a alloy fork and headset for really cheap from this shop I used to work in. Id be putting it on my 83' Trek 720 frame. Right now its my only road bike and a little undersized.
Iam looking for weight reduction,durability,and comfort.
Another added benefit is that since there are 700c wheels in this 27inch frame I can use my good brake if I get the alloy fork.

Cheers

Harshest ride for me ever was an aluminium frame with aluminium forks. Mind you, this was a modern 'oversized' frame with bladed forks so I can't comment on the Duralinox era.

Just like any material, it depends on the design and construction. I've had three different Al forks on my old Trek... As far as I can remember, the first fork ('87 Trek) rode well, but the right side dropout cracked while riding along. I was riding a tailwind at 39 mph at the time and it felt like a flat tire. Bad fork, but since it was the dropout, I don't blame the fact that it was an Al fork - plenty of carbon forks have Al dropouts. It was replaced under warranty with a Vitus 979 fork painted to match my frame. That fork was also good. Then I cracked the right rear dropout in the frame and Trek replaced it along with the fork. The replacement frame and fork was standard issue '88 Trek 1500. This fork was different than the first one I had in design and I believe it was made by Tange. An excellent fork. Nice ride, the frame and fork are stiff enough and I don't ever think about it or notice it.

There may be bad Al forks out there, but it's due to bad design, not material.

Guy traded a buncha parts from an Ultegra Gt TR2.0 bike with a damaged top-tube, thats why the shop wants to get rid of the extra fork that was upgraded to carbon fiber.

Iam gonna get it tomorrow

I did want to defend Al forks, but I wouldn't say that it's a good move for your bike (I just noticed your reply above). You have a decent old touring bike and the fork on that is longer because it has more tire clearance for bigger tires and that's on top of it being 4 mm longer since it's for 27" wheels. It also has more fork offset (rake). The shorter Al fork will steepen the angles a bit, which will move your seat forward relative to the bottom bracket. The increase in head tube angle will probably be offset by the smaller offset of the Al fork so the trail might not be changed too much or will be at least within an acceptable range. But it just doesn't seem like an upgrade to me. You are replacing a fork designed for the frame with another with different dimensions and a different look. You're just making your intact semi-classic touring bike look more like something retrieved out of a junkyard. The weight loss will be negligible overall and I'm sure the steel fork rides fine. Of course if you want to mess around and experiment, or your fork is trashed, or you like the mismatched frame/fork look, that's fine.

What's wrong with the current brakes? I think the cantilevers should be able to handle the smaller 700c wheels (both ends I hope).
