Back on topic: this is a great drive train study and very useful info for any of us who are considering the new IFI wheels.
Thanks and props to 1114!  |
There was a thread a few months ago about aluminum sprockets, in which Tyler described how 1114 cut their sprockets on their CNC mill (Infact, I believe the example he showed was this exact sprocket
)
As to the wheels themselves, the rookie team we mentored last year used them, and their problems stemmed from the wheels loosening themselves unless you use loctite. The problem is when you use loctite, you break the press fit of the PEM nut into the side plate, and you have a useless wheel. Having a locknut now should resolve that issue nicely.
