I don't know you, and I trust you're well aware of the risks (stress risers!) and weaknesses created by all the holes you've drilled... However, this post still makes me feel like a mom: I'm concerned for your safety! I remember the 90's, when folks were doing this with Campy parts and other bits to shave weight. Almost all the drilled parts eventually ended up cracked at a stress concentration point created by the hole. If you're light in weight and light on the pedal input, maybe this will be OK for a bit? Sure looks nice, thought! Bruce!

Could you perhaps thread the crank holes and have multiple crank lengths? Very nice. Could you perhaps thread the crank holes and have multiple crank lengths?

I remember the drillium years and also remember a friend laying in the middle of the road, dazed, with a crankarm still strapped to his foot. :) Of course, at least you won't fall over! It may be a long walk home, though! :D Pretty cool, though, I must admit! Dennis T Careful there, Bruce!

Bob neglected to mention that the 13.7 lbs is from the trike starting at about 36lbs! It sits at 22lbs, 3oz right now, with some lighter front wheels coming from PowerOnCycles, and a new carbon rear der in place of the drilled Deore XL der. That, alone, is worth over 100 grams, or about 1/4lb! When everything is done, it will be well under 22lbs. Clarification!
