"Who Knew" show Trek bike construction
Did someone catch Marshall Brain's show the other night
that feature Madone bike construction? It amazed me how a lot was still done manually. I was also amazed at a statement one of the Trekkies said when describing the stress test (referring to a Madone frame) that if he left the frame for a year it'll still be there on the setup - being stressed with no cracks, stress points, etc. Also they showed how the seat tube "flexes" for comfort; is this your (owners') experience? |

Frames are tested beyond the threshold of pain produced by normal users. Otherwise Trek would be otta business. the stress testing machine(s) are built by the machining dept from designs drawn by a stress testing engineer. It's quality structure built to repeat the same motions over and over thousands of times and measure what's happening. That's more or less what we see here in RBT. Once in a while someone will 'claim' to have a broken carbon fork or even rarer a crack in the frame. the forks tended to be off beat brand forks sold at discount. All those I saw were road bikes, no outsight $$$ carbon MTB. like when I see a Lightspeed itsa big deal, never see a plastic MTB. I grew up when plastic was an inferior substance. I am amazed at cateye and crankcrick grips resin plastics. Buy a Nadone? Nodway. cheap plastic. waht's the point? I will stay up for the Baboon GP, marveling at plastic F1 cars. And whattsiname that ran over the japanese slug in Kentucky or Ohio. GOOD LUCK DC! |
