Looks pretty good. Please share your next attempt - curious to see how much you'd save on a nice light pad holder.

Couldn't you replicate the cut out on the opposite side of the mounting bolt? And ditch the unnecessary hardware!

Did cut the weight in half here but without the pad holder bolts... which i think i dont need. If i put the brake pad in right when i brake i just tighten it on.

Yes i think if i drill those 2 holes a bit bigger and then dremel it out again i’ll be saving some 2 grams over the 4 pads. I’m still going to try this but i think i will lose some strength of the brake shoe.

Brilliant, better patent that one!
I guess there's worse hobbies than making a bike light? Right?

I can confirm that is extremely user friendly, fast to place the watch and take off, weights nothing and I can’t barely notice that it’s there

It works really nicely, Xpedo XPR cleats with chopped off sides so I could use the threads, two titanium bolts drilled from inside and flushed with the outer side of the cleat for a flat surface to glue the rubber on top.

Setup is paired with a set of XPedo R-force pedals.

No issues without the top bearing cover?

Good catch, I’ve being biking for a long time without star nut and cap, no issues at all

Here is a cheap pedal mod I did. Bought a cheap SPD pedals for my road bike, same as the ones I have been using on my MTB without any issues (I prefer SPD even for my road bike). Stock at 260 gram.

Converted to one sided by simply unscrewing one side of the clipping mechanism then filed away as much of the remaining alloy...30 minutes work...and achieved 216 gram...cheapest weight saving I have done.

That's pretty cool, especially with the Ritchey 1-sided SPDs discontinued!
