ISIS standard?
- Thread starter SOil
- Start date
are you making new/old technology bb's 
?
?
Chris King's website has a bunch of stuff about it, including drawings and the specs.

Yeah outdated technology would be more appropriate.SOil said:
Yes it is, you dont think the outboard stuff will totally replace it soon? There is no reason to run isis. No advantage...unless you like loose cranksSOil said:
:mumble:
what planet have you been on newb?SOil said:
Aliens from planet outboard bearings told me.SOil said:

while the thread is about cranks there is alot of bb talk in there...it is pretty representative of the industry direction. I dont think anyone would argue with me in the fact that isis is on its way out, outboard is...well..."in"
I'm really not sure what you are on about...
I'm fully aware of the use of ISIS spline and other interfaces used in the past and present, having worked in the bike industry for several years.
The reason I was looking for the design standards, is because we are considering manufacturing (isis) cranks, hence needing the engineering drawings for the ISIS drive standard, in order to model them.

gotcha i was just curious why someone would begin developing them now?
goodluck

Do a google search. The engineering drawings are out there for free download.
ISIS has it's issues. Mainly short bearing life. The form of the spline works, however, the size of the spindle requires that the bearings be very small.
This shouldn't affect crank manufactures though. I suspect we will se more of the Truvative approach. They have a new ISIS BB with outboard bearings. They aren't reverse compatible with thier old cranks, but it's a step in the right direction.
