Vallie Components - bicycle part and accessory design

I've been in contact with Sam @ Tree Bike Co about their 9 keyed spider, designed by Phil Wasson of Super Rat Machine works. Sam is still undecided about whether or not to make that part 'open source'. Still, I've gone ahead and continued optimizing the design for use on a fixed gear.

Its hard to cut down a 10mm thick pie plate and have it both strong and light.
I've changed the look around from the previous Tree inspired design, to a more conventional 5 sided look. Material has been removed where it makes the most sense.



Its funny that I've been so inspired to work on a project that wouldn't really be for me. I don't ride my track bike in this manner, so this part may never go to production. My BMX is for stunts, and my track bike is for training. Just who would I be making this for?

The community.
The people that are pushing bicycles beyond their intended capabilities.
I like those people.

Here it is, The Vallie Components Blog. Not much content yet, but I'll be updating it as I come up with more ideas.

I've been busy working on a spline drive Bash guard chainring spider recently.


I hope Tree is receptive to this idea. (I had to reverse engineer their 9 keyed spline insert from high resolution pictures on the web)

It adresses the problems encountered when running Profile style 48spline 19mm spindle cranks on a fixed gear bicycle. The traditional single bolt does not hold up to the torques generated in both directions due to cranking and backpedalling.
This also has a giant bash guard on it, for the grinding crowd.

...more to come later =]
