Wow, the the hell do you guys do all day when I'm not home, sit on your damn computers all day.

My day starts around 5:30 or 6 in the morning. I have a bunch of mail to check before I go to work, plus I try to check the good bits on here. At work, I have access all day, and I work from about 7-5. After dinner, I usually have some stuff to do online, along with 3 websites to maintain. So yeah, I'm pretty much online throughout the day. When they hire another offsider for me at work, I'll get to leave at a reasonable hour and ride after work.

Beerman's a geek? Never would have guessed. I work in transport, so I get to dodge trucks and trains all day. And fork lifts too.

One question, what is that?

14mm hollow axles are actually stronger than solid axles, the reason being that it's harder to be a tube than a rod.

Now how exactly does that work? If I were to take a piece of PVC I could bend it over my knee, but if I filed it with sand and tried the same thing, I bet I couldn't bend it.

PVC is inherently weak. But a 2 foot length of PVC pipe is still stiffer per pound than a solid PVC rod.

The olny point I was trying to make was that by filling something hollow with something, that it made it stronger.


You are a dumba*s.

Ooh, so i'm guessing you knew all along how a hollow piece of metal can be stronger than a full one?

Well, would your frame be any stronger of you filled it with sand? And would that improve the strength/weight ratio?

The sand was just an example, but if you made a frame out of Metal(not hollow), then yes it would be stronger, which is what started this question. I was not wundering about the strenght to weight ratio, because all Beerman said was that Hollow axle are stronger than full axels. He said nothing about strenght to weight ratio.

A frame made out of solid bar would be very weak. Forget about the weight. A solid rod will always be weaker than a hollow tube of the same diameter.

ive come to the conclusion that getting a totally new bike is the way to go im thinking about a haro backtrail X3

I'll point out that I don't tell people to buy them just because I bought one. It's the other way around. I suggest them because they seem to be a decent bike for the price. It may not have all the name brand parts, but at least it's spec'ed out with durable components. I'll post a photo of mine after I finish taking all the crap off it.

Now go vote (http://www.bikeforums.net/showthread.php?t=149118).

reviving an old thread and not starting a new one

anyway i chose to get an eastern element and it has a fit press BB or something like that.. i was wondering if brands make cranks this size and if so which ones?

i am also thinking of getting sun big city rims good or bad idea?

You just buy the Mid BB bearings to fit on your spindle seperatly most of the time. I'm not sure if any cranks yet come with Mid bearings.

As for the rims, get a Hula Hoop rear if your hard on your bike/bikes, if not, then I would suggest a Odyssey Hazard Lite.

All Profile and Odyssey cranks with American bearings work with the Mid. Just don't use the cups.

US bb was used by many companies so they coud use cheap 1 piece cranks on thier bikes. mid is the same size bearings as the sealed bearing in US bb's but without the cups so it is smaller. its to save wieght i geuss. they have like a litte raised lip inside them that stops the bearing going right through the bb and they just pop fit in.

correct me if im wrong about anything.

can some one tell us about the euro and spanish bb's. i have no idea.
