Bullbars
These blanks were cut with enough material to accommodate a 40mm stanchion, but are only bored out to 31mm. Future renditions will be way slimmer on the rear end. (Sorry, Brazilians)
Bacon dispenser needs Pez-like flip-cap to regulate flow.4130biker said:
faulty logic. you're assuming one would want to stop the flow of bacon.
Whoa now, this is simply to regulate flow- never stop it! Keep in mind that the standard flow holes are always open.
Shimz regulate flow. And your design has none.
Other than bar flex, you have to kind of keep in mind that any good direct mount/bolt on stem is already doing exactly what you're after.......in theory at least. Even a bolt on stem gets leverage from the top crown and hence stanchions. You'll be transferring a lot of what normally flexes a fork radially (twist) into what's now being fought by the handlebar.......which is now clamped in an area that no bar on the planet was made be clamped in. So that's one area that's not necessarily a fault of the theory of your design, but a potential one with existing available materials. But that reduced leverage comes into play there too. Just keep in mind the tapered walls of most handlebars.Tell me how you really feel.
Just kidding. I actually welcome the criticism. It lets me know what I need to focus on to improve.
I understand the concern about clamping onto the threaded portion of a tube, but there is also a large nut underneath to support the tube in that portion, if that's where the clamp is placed.
I do take issue with the bending/twisting concern. The widely-spaced supports will take much more axial (up/down), and shear (fore/aft) force from pressure on the bar. A standard stem on steerer tube is all twisting and bending on a single tube of roughly the same diameter. The tube wall on the stanchion may be thinner, but your forces are applied in a much less stressful manner. Also, your lever length is reduced on either side. Instead of 2 15" levers applied to a 2" wide structure you have 2 12" levers acting on a 6-7" wide structure.
The weight concern I cannot combat until I have real numbers to provide to you. I will just have to prove that with the next generation.
