I cant help but laugh at the bike companies that are advertising investment cast dropouts, head tubes, BB shells, and what have you as a good thing.....LOL. Thats probably the oldest and weakest way to produce metal parts. Parts are lighter due to all the air, hence weakness, and can have serious porosity which will not appear until the part fails if its internal. Old style components that are stamped (forged) are much stronger. No wonder new parts have to be 1/2" thick...LOL. Yeah, you can get nice artistic details in the parts....its also way, way cheaper to do, thats why new bikes have them. Billet or forged is the best if you want strength, and durability....cast is just one more way for them to reap profits at your expense, and then market it as a good thing.....its not.

Oh gee,another thread to bash NS bikes and it's design,not surprising at all.

Well it seems that so many are quick to say that NS bikes are vastly superior in every way.....show me how....investment cast parts=fail, Hi-tensile steel=fail, Small <weak> Euro style BB=fail. I could go on...these are just a few metallurgical actualities not my personal hangups...these are facts. So how are they superior again?

Seems to me you have a theory but are lacking the evidence to back up you claims. If your theory was true we would see lots of broken frames. Not saying you are wrong but if you are going to make grandiose claims against bike companies who are actually producing a product (and you are not making anything) you had better bring it. Your "everyone knows" argument is without facts and until you have supporting facts it is merely opinion. How about we start with your "metallurgical facts" and you metallugical credentials...

I once saw a person ride a RL20II off a curb and snapped it in half.

Huryupanbuy · 2012-11-25 3:34pm

How is a euro bottom bracket weak? It's almost the industry standard for new school race bikes...I actually can't even think of a company with a current race frame that makes their race bike with something other than a euro bottom bracket...That covers race bikes. Now for dirt/street riding bikes...I imagine the reasoning behind them having a bigger bottom bracket(spanish/mid), is to accommodate the bigger bearings for the bigger spindle. That's only my opinion...I'm not a professional.

But what about the race cranks with a bigger spindle? Outboard bearings...

dedmann · 2012-11-25 3:41pm

picture of said weakness and failure.
i think that most frame breakage is from heat street from over lapping welds. the investment cast is 1 continuous butt weld. no? not better?

C'mon guys, just leave him alone.

This BMX thing isn't easy when you are 41.

Yeah, easy to understand.

JC82 · 2012-11-25 4:14pm

Id like to know how many companies are using investment cast pieces in frames? Because i dont think its all that many.

The only one I can think of off hand is We The People /eclat.

Fly bikes is also using it on their frame and forks.

This.

I don't get what's so terrible about Euro BBs. I have a Euro BB on my custom trail/park FBM and have/have had several other frames with them as well. The only issue I've had with the bearings was after it got caught in a massive downpour and somehow water made it into the bb shell causing an inboard bearing to seize, but that could happen with any size/type of bb shell. As long as you're not doing huge drops to flat, a 19mm Euro BB should hold up just fine.

I wonder how many sand casted Ferrari blocks and parts are failing?
