Aluminium frames
Further to my thinking regarding money spent on bikes, are aluminium
frame road bikes pretty much of a muchness? At the lower end of the scale (sub$2500), I don't imagine that many brands would design a frame in house, as there would be little to no margin in the sale after gruppo's and accessories are taken into account. If considering upgrading a frame, would you need to look at (ballpark) $2k for the frame and fork before you found a 'better' frame that wasn't just bought blank and had stickers slapped on it?

No. The really cheap ones can be (and some of the expensive ones too ...), there's a book that comes out of Taiwan or somewhere (I haven't seen it; but know of its existence) that allows a 'manufacturer' to pick & choose various shapes etc and 'build' bikes by the numbers from the book, but not all 'manufacturers' use it. The bigger name brands that I know of don't. Trek & Cannondale I know don't, they have, at least, their own designers, and all the Cannondales were, and I think still are, but am not sure about the new Synapse's, made in the US *except* the CF synapses! Trek's higher end Al Alloy frames are US made too but the 1x00 series frames are Taiwanese made. I *think* that Inexa use 'the book', but am not sure, I don't know enough about other brands to say. 'made in Taiwan' doesn't necessarily mean thrown together out of the book, although there's a distinct chance that it is.

No. There are good frames at the sub $2k range, and there are dungers. Go testriding, you'll be able to tell. I have a sub $2k Al Alloy roady at home that's been very good to me. |

I too have been wondering about aluminium alloy frames because I am just about to pension off a couple of old 7-speed MTBs and buy another hardtail. In another post about the weight of duallies there was a URL to a Scott bike that has a 7005 frame. I was in the CBD the other day and saw GT and Norco bikes with 6061 frames. Any comment on either alloy? regards, Darryl |

Any comment on either alloy? I'd have to double check to be sure, but it's differences in the non-Al parts of the alloy, and it changes the behaviour of the metal a reasonable amount. Off the top of my head 6061 is a touch weaker, but easier to work. This means you get a slightly heavier bike, but a fair bit cheaper. 7005 needs heat treating after welding, but is a bit lighter. Then you get into the funky custom alloys, like Easton. This is based on some very fuzzy memories, but should give you some pointers for Googlage. -- Dave Hughes | "Until we understand quantum gravity, we're not going to be running Linux on a black hole" - Seth Lloyd |
