Steel forks on alluminum frames
I've got a rush hour pro that I commute with on some crappy roads. It's got a stock cf fork.
I've been looking at a lot of the '90 gen cannondale track bikes (also alluminum) and wondered about the fact that they have steel forks. From what I gather the bike was praised for being so rigid. If so, why not go with a alluminum/cf fork as they're more rigid (atleast alluminum is)?
Let's say a steel fork would really improve my commute (brick roads, good pavement, bad pavement, random obsticals thrown into the street, really deep random pot holes), where could I find one for under $100? I looked into the Surly steamroller fork, but I'd like to find one with zero rake. Thanks.

If you call up Tony at IRO, he might be able to sell a fork from a Mark V. I have no idea if he will, just an idea.

I don't know why I would want to switch, that's why I asking in the first place (like why did the cannondale have a allum frame + steel fork?). Plus, my current fork basicaly has no rake, so anything with rake will slacken the geometry

Call me stupid, but I'm pretty sure your fork has some rake. Maybe not 70s touring bike rake, but it has to have some.

Yeah, most if not all straight blade forks have the fork blades (legs?) at an angle from the steerer. so they're straight but still have rake. Mine is like that, too. Now we know that, we only need to figure out WTF this thread is about.

ok..
Why do canndondale track bike have steel forks - why did the designers choose steel over alluminum or carbon fiber?

For applications like forks where repetitive stresses are high (in both frequency and amplitude) steel has fatigue limit and aluminum doesn't.

By "has a fatigue limit" Scooper (Anvil) mean that there exists a stress level under which the material can tolerate an unlimited number of stresses. (=> a steel frame can last forever if not rusted or crashed, an Al frame can't. Sooner or later it will crack even with normal use)
BTW, Anvil say that Ti frames are heavier than Al, only just lighter than steel. Way outdated info. The current lightest production frame is Ti afaik, and Ti is certainly a lot lighter than Al.

LóFarkas has it right. Please read the definition of fatigue limit. The OP asked why Cannondale uses steel forks on aluminum frames. I believe my answer to the question is correct.

They haven't used the steel forks for at least 6 years on their trackbikes. ("Major Taylor", "Messenger" and "Capo")
