Carbon VS. Aluminum
Hey everyone I posted a few days ago about my Roam 2 and got alot of good tips on what to do now that im trying to upgrade. So far ive been able to rebuild my bike and make sure all parts are up to par. Now im looking into replacing my fork. I never use the suspension part and it seems like switching forks may make the ride a little lighter. I was going to go with aluminum but after hanging at the local LBS Im on the fence about switching to a carbon fork.
Anyone done this and noticed any changes as to the positioning of the bike itself and handling?

You have to make sure the fork you buy--whatever the material--is the same length from headset to dropouts as the suspension fork it is replacing, or your handling and balance will change in possibly unpleasant ways.

TBH never thought of it just because no one brought it up to me as an option. It defenitly be more durable. Do you think with my commute being on mainly paths and roads I ride around 40 miles a day. Would it be worth keeping a heavier fork on? Im debating on switching it just to make it lighter for the most part because i keep about 20lbs of stuff on me + a 9.6lb security chain. Mixed in with my almost 300lb self im trying to get rid of what ever excess weight I can.

AL forks tend to transmit the maximum amount of chatter----high-frequency vibrations---right into the palms of your hands, which can b wearing over time. Steel and CF are a lot more forgiving. And while there is nothing wrong with steel, CF does all the same stuff and weighs much, much less. Unless you want to carry 50 pounds in your front panniers, CF is probably the best choice.

I also always enjoy reading posts on bass guitar forums from people discussing the differences in tone between, e.g., ash and alder solid-body basses. The more imaginary the differences, the more heated the arguments.

If the goal is to reduce weight, then carbon is the obvious choice. Buy a good quality fork and ignore the bs about durability.

Confirmation bias. My favorite track bike has an aluminum frame and aluminum fork. I've done many road rides of over 5 hours on it. No so-called "chatter" issues. It rides exactly like a bike.

Plenty of room for different opinions ... I believe---based on a lot of riding, on a lot of bikes---that a CF or steel fork would be a little more forgiving than an Al fork. No need to toss around derogatory labels, just because you disagree.

got 2 of each and..
+1 on this. With the hills around here buzzing hasn't really been a problem but but carbon and steel handle large potholes much better than Al. (In so far as saving the wrists).

If you are riding on mostly paths and roads there is NO need whatsoever for a suspension fork, I would just get a steel or carbon rigid fork, carbon is lighter of course.
Unless you are are doing aggressive down hill single track racing there really is no need to use a suspension fork.
Which should you get, steel of carbon? depends on how much the bike is worth, if it's worth less than $500 I doubt it's worth putting on a $300 or so carbon fork, if the bike is worth over $1,000 then the carbon fork would probably be the right choice, in between $500 and $1000...hmm, depends on if you want a lighter bike or not, and is you want to spend the money.

I agree that there is no need for suspension when riding on roads and paths...Personally I don't even use suspension when riding singletrack trails. I have two mountain bikes with rigid forks.

Oh, BS. It's not a misleading test. They broke a frame that had failed to break under previous testing and then been ridden for 2 years by a monster for Pete's sake.
Where's your delamination?
The only caveat is that they are testing mtn bike frames, which are built much stronger than road ones.

I rode my MTB on a flat paved trail for 43 miles just to see the difference. I won't say I can prove I lost energy but the senseless bouncing of the front end was annoying and sure made me feel like I wasted energy. But I have no electronic proof or I would say that I did.

--------------------
By the way, Big rider, carbon forks since 1998, never a problem with durability.
Aluminum frames, snapped #1 at 13,000 miles..........snapped #2 at, you guess it, 13,000 miles (plus a few but withing 13,000+ range)
New carbon frame, 15,000 miles so far, no problem or signs of giving out soon.
Aluminum bicycle. Others have told me that alum was no good and that I would explode doing a long ride. In 2005, I did 23 centuries, posted over 7,300 miles that year on an aluminum bike. The people that made those comments have never done a century.

My Trek 7.5 FX has an AL fork. There is a lot of vibration and road noise at the handlebars. Switching to a CF stem and handlebars made a big difference.
I your case, I'd just switch to a CF fork.

Lots of factors to consider including but not limited to: Cost, road vibration, riding habits, terrain that you ride, size of tires you can fit, um I'm sure there are others but cannot think of them right now
I have an all aluminum bike and it has a fair amount of vibration, but not to point that I don't ride it. Also, have a steel bike that does not vibrate as much. Usually I will alternate between the tow on a bi-daily basis.
Would love to have a carbon bike but cannot swing the cost
Carbon fork seems to be a good option, but again, how and where you ride are big factors

Surly Cross Check disc fork might do the job if the axle to crown length is within 20mm. Have two of them on bikes, one steel, the other titanium, and confirm the ride quality is excellent. Not stiff and not lazy, but just right.
