Thumbs up Re: Aluminum Frame or Steel Frame?

... Thank you for the heads up. I have a Trek 4300, it has Alpha Superlight Aluminum Frame. As Trek calls it. I was thinking about buying another to motorize. Wasn't sure at all before I asked. But now that I have a better picture of the materal aluminum. I'm going to pass. Heli Arc isn't cheap, Let alone getting into retempering the Aluminum. And as far as the 3/16" X 9/16" thread holes I spoke of, there is no way you can. As it is, it appears to me now, these riveted in place theaded holes, are a weak spot in the structure of the aluminum. I've used electric Arc and brazed many years. Only ever watched someone else with Tig err Heli Arc.

... Steel it is ~~~
