Since there were so many custom parts and designed elements on with the Oregon Manifest design competition entry that I worked on with Geekhouse Bikes (see geekhouse/aarn: oregon manifest utility/cargo bike [bicycle]), I decided to put together a post with a few shots of the raw dropouts. I went by the machine shop the other day and the machinist had made an extra set of these for me.
On the final build, these dropouts were slotted from the back - much like a normal track dropout - but originally these were a modification to a 5mm allen head dropout that I designed for Marty prior to 2011 NAHBS. I designed simple front and rear dropouts that both used a stainless steel carrier which allowed for a flat head cap screw to be used with hubs featuring internally threaded axles. These didn’t make it to the show for a few reasons (the customer didn’t like them)
- so I’m going to ghost-of-done these onto my blog.
[edit: drawings removed - I guess they are going to go on a Geekhouse soon - Stay tuned for that]
So, anyway, the OR Manifest dropouts were standard 20mm track nut versions of these dropouts that never got made. Plus, the tabs were designed so that they could be slotted right into the exact diameter and bend radius tubing that was used for the “stays” on the manifest bike.
The rear end of the manifest bike was a little more rigid than Marty had expected, so it just made sense to slot them from the rear when the bike was being built - especially considering that they were not designed for full-width axles.
Just some ghost-of-done stories before Halloween for everyone. I’m just going to keep referencing this until everyone is on the same page.
