Flyboy - Quit while you are behind. You don't need to make individual posts for every single comment - just one post. You can do multiple quotes if you want, but even that you don't need to do. Just say your bit and move on.
A good rule of thumb is that when someone calls you a ***, simply agree and change the subject. It has been established that all bike riders are ****, especially ones who are pompously proud of the city they live in or the websites they run and it doesn't matter if they are married and have kids... they are still ****.

Aluminum is not brittle.. It's not like a rusty cracker or something. The deal is that by definition, steal is stronger than alluminum; but when you're talking about cranks, that really doesent matter. I have profile race cranks, I am a very big guy and have had them for over three years. I broke one cranks arm once, but I sent it back to them and had a new free one in under a week... its garunteed for life, so why get heavier cranks. As long as the cranks are designed well for your purpose it dosent matter steal or aluminum, especially if they're garunteed for life. Differences in flex and all that dont really effect street riding, if thats what your doing, it may play into racing where flex may win you or loose you a race, but not really freestlye riding. Philly, what what.

Steel also has different flavors that make it stronger, but more brittle, or weaker and less brittle. 4140 for example is stronger than 4130, but it is more brittle which makes it less suitable for frame building, but better for axles and perhaps cranks. Frames, forks, and bars really need a tiny bit of flex to survive the rigors of street use.
I rode a GT Show for a little over a year. It was an aluminum frame and I rode it the same as I had any other frame. In one day, the frame developed a crack. By the end of the day, the frame had developed about a dozen more cranks and broke in a completely different area than where the original crack appeared. When aluminum fails, it fails pretty much completely. I wouldn't trust aluminum on street, even if the cranks will last a year or two, when they break, I probably wouldn't have any warning. Chromoly is much more likely to show cracks and give you at least a little warning.
Besides, Profile cranks kick butt.

That is right, when aluminum decides to take a 'break' you'll be the one who's taking a break for the next three months. And also BMXTRIX, doesn't cromoly bend before it breaks?

Yeah, they definetly do! If my new Redline Monster cranks ever break, I'm going straight to Profile! I mean how can you beat that lifetime warranty?!! Oh by the way, I did finally get my Monster cranks in the mail... and they are as cool as a new car interior!! Nothing like a new crankset huh? No, but really, they look awesome and I think they'll definetly last me awhile.

Chromoly doesn't necessarily bend before it breaks. Typically this has to do with areas where 4130 is welded. Welds increase brittleness due to the intense heat/cool down cycle that goes on around the steel at that point. With cranks, it is very unlikely that chromoly cranks will break in the middle of the crank arm. It is much more likely that they will break right at a weld due to brittleness. Cranks not only have welds at both ends, those are also the major stress points for a set of cranks so likelihood of breaking them there increases.
Heat treating and stress relieving can all allieviate brittleness though. Use of 4140 can also help reduce breakage due to increased strength.

However, the pedal bosses on aluminum cranks invariable suck; if they have a threaded steel insert, it generally ends up threading out, and if they have threads cut into the crankarm, they often end up stripping or crossthreading.

you started this thread asking the question"are chromoly cranks stronger then aluminum?"how would you know that you like chromoly better than aluminum if you never rode either.

Ok metal is not somthing to argue about. Chromoly is stronger than aluminum. THeir are places where Aluminum is better to use. Likewise for Chromoly. Some people will say they like alum. cranks better. Others crml. What material your cranks are is quite pointless to argue about. If you ride well and your cranks dont bend than you have found your cranks.

I have cromoly cranks on my bike right now, I just wanted to know wich was stronger! So before you start off again on your little persecution bit, get you facts straight.

i have had both profiles and primo powerbites and they are both strong enough for the masses. Its the design of the cranks that make them strong.
personaly i dont like the profiles because they never stayed tight, once they get lose and you ride home the arms are f**ked, they will never be the same again. the powerbites on the other hand have pinchbolts so there are three bolts holding them tight, its a fit and forget design, never had a problem (my cranks have a steel insert for the pedal thread)
Now that sounds like an insult!
You must have lead a very shelterd life, this is humor. Take it on the chin with a smile, give some back and get over it. LIGHTEN UP

I have PRIMO Hollowbites that havent given me and trouble ive had them since Christmas this year and they are only 1 ounce heavier than the Profile cranks that everyone has....but i have never had trouble with them so far.
