Many thanks to Steve DeOreo for the article scans. I'm having a re-fascination with the drillium craze since coming into possession of a N-Rec rear derailleur that is one of the most drilled and milled derailleurs I have ever seen. This derailleur came with a black anodized S-Rec group I recently acquired. Upon close inspection, the derailleur has been attacked just about everywhere possible. The more you look, the more you see work done. This prompted me to start thinking about the end weight achieved by this process, and the articles just further fuel the flames. I've posted pictures here:
I hope to add both more photos and information to this album in the future, but for now it's a start. I also want to try and see how far this has gone, weight wise. I decided to start by pulling out a box of derailleurs and began weighing them. This super drilled/milled derailleur weighs an amazing 143.5 grams. Here is a further tale-of-the-scale:
C-Rec 1st Gen stock = 209.5 PAT 83 N-Rec stock = 199.5 PAT 73 N-Rec stock = 198.5 No Date later S-Rec = 182.5 PAT 83 N-Rec with Ti upper and lower bolts = 177g PAT 77 1st Gen S-Rec stock = 174.5 Mavic "erector set" (SSC?) = 173g N-Rec black milled/drilled = 143.5g
The only Huret Jubilee I have currently is mounted, so I can't weigh it. Does any know what the weight was? I seem to recall that the drillium Jubilee actually weighed about the same as the non-drilled version due to added support on the cage. Anyone got a pair of those and a scale?
I'm heading out to VR next week and will be bringing along the derailleur for a little show-and-tell. Anyone else attending want to bring something similar for comparison?
