This stem is beautiful-will you be using it with a carbon handlebar? What is the stiffness of this thing?

Great looking stem! I have always liked the looks of the few polished alu stems that are out there. I would leave it like it is if the color works ok with the bike its going on.

Alu bolts on a stem......I think not. Only on the steerer clamp if at all. I think you would be hard pressed to find anyone here that uses alu on the face plate!

That's what i was just thinking. Alu isn't strong enough to be used for stem bolts. Use titanium instead.
For if life, in the desire for which our essence and existence consists, possessed in itself a positive value and real content, there would be no such thing as boredom: mere existence would fufill and satisfy us.

First of all, Nice work!!! Definately a piece of art! It'd be interesting to see how it holds up. I'm by no means an expert but it looks a little thin in the clamp area around the front of the handle bar. Hope it works out for you! If it does we might be begging you to reproduce it :wink:

Very nice CNC work.

but have you tested this design for strength? You're not going to mount it on your bike and just go riding are you?
