that's 100% bizhouse rip-off, no?no. please keep remarks like this off of the thread please.
i was asking an honest question though.
To answer your question, I designed this stem as simple as possible to keep the weight down a bit. I have never seen a Bizhouse with slotted holes in the sides untill someone sent me a photo after the design and stem were both complete. This was based off a block that would be made simply and have an optional 3 reach design, thats all, and thats what our stem is.
