Yea the barends are totally sick. Its awesome how you machined the back of them so that they can act as the outside lockring for odi lock on grips. That is definatly a great idea that needed to be implemented. big thumbs up for sure!! I guess you got a run of pedals and stems done for the upcoming season?

can you make a 35mm reach, 1 1/8 and 31.8 clamp?

VERY VERY nice stuff btw
you couldn't make a stem with an internal steerer clamp and 31.8 bar bar. At 35mm, there would be less than 5mm between the steerer and the bar.

Nice so that makes it stronger then the 7000 series aluminum right?

Try again. 7075 is way stronger than 6061. The only reason bikes are made from 6000 series is cause it is easy to buy and easy to weld. There is no good reason why a machined part should be made from 6061 unless your getting cheap. &075 is twice the price of 6061.

A Cannondale(who uses 6061 T6) rep said that after the heating process and it is dipped in a special coolant, it is stronger then 7075. And 6061 is lighter then 7075 after heating process.

BS. Here's the pecking order for common stuctural aluminum. 6061, 2024, 7075. There is a reason you see very little 6061 on commercial airplanes.

The weight is so F'in close that there is no way you could tell the difference. Both alloys are 95% alum. How would the heat treating process change the weight?

Don't believe anything a rep tells you.

Exactly!
Each series varies slightly in weight and density and the hardening is done by solution heat treatment or solution heat treatment and artificially aged so the weight would never change.
The reason why most people use 6061 is the cost, 7075 is almost twice the price per lb.
But 7075 series aluminum has almost twice the tensile strength of 6061-T6 and its a little bit harder to machine as well as keep from discolouring, mainly from Zinc which is the major alloying element in that series.
