More anti-aluminum "facts"
It's all IMVAIO, and open to debate of course. But not Navas-style debate.
It's going to be tough to avoid that when your website make statements like this- "Avoid aluminum frames at all costs." or " All touring bicycles have Chro-Moly steel frames for durability (aluminum frames won't stand up to the rigors of fully loaded touring)." And then later on you give all manner of anti-steel references (what a surprise that most come from steel-frame specialists), as well one from bikexchange.com that "No aluminum is going to hold up as well as steel." Just exactly what is it about a bicycle that can't take advantage of many of the useful aspects of aluminum, but an airplane can? Why aren't we worried about planes falling out of the sky? Opinions masquerading as fact are dangerous things. The fact that's missing from your pages is that any of the commonly-used frame materials (steel, aluminum, ti & carbon) can be used to make a great, long-lasting reliable bike, or a dog. It's not the material, it's how it's used. It's especially wrong to scare people about the fatigue issues with aluminum, since that's a design issue that's easily dealt with (by simply building it in such a way that its fatigue limit wouldn't be approached until the frame is ridden a distance that would greatly exceed the point at which a high-quality steel frame would suffer a failure; in general, my rule of thumb is 35-50,000 miles for the steel frames I've seen over the past 30 years). But nothing I'm pointing out here is news. The relative durability and desireability of the various frame materials has been hashed to death repeatedly by knowledgeable engineers who know something about the structural properties & issues... right here in this newsgroup. In each case, I explain in detail the actual reasons than manufacturers choose to make certain changes, as well as the rationalizations they use to defend those changes. I explain why, despite the cost savings, many people believe that these changes are undesirable. This is not true; you're still claiming, despite evidence to the contrary, that a threadless headset costs less to incorporate on a bicycle than threaded. You also state (on your website) that "Unfortunately, except on very high end bicycles, the steerer tube is cut to the minimum possible length at the factory." This again is *easily* verified as being untrue. You can drop into either of the nearby shops on Foothill Expressway and see that at least one major manufacturer sends out all of their bikes (inexpensive & high-end) with 4cm of steer tube between the headset and stem. And in your Compact geometry section, you state that they're done to reduce the number of sizes to 3 or 4. This ignores the number of companies that offer just as many sizes (6, 7 or 8) in "compact" frames as they do for standard ones. The truth? If anybody can handle the truth, for most companies, compact geometry is all about style. They look different, some people (not me) think better. If a manufacturer incorporates compact geometry but doesn't reduce the number of sizes, there is no cost savings. You offer some good, solid information on your site, but it loses credibility when it strays into opinions that aren't based on fact. A sensible re-working of the threadless headset section would point out how adjustability is offered in both threadless and threaded, and how to take advantage of such options (and make sure they haven't been precluded by, for example, cutting the steer tube on a threadless bike so short that there's very little room between stem & headset. In the section on compact geometry, you should point out the importance of sizing based upon not only "height" but also top tube length, and how, if a brand offers only sm, med & lg, you're not given too many choices! --Mike-- Chain Reaction Bicycles http://www.ChainReactionBicycles.com "Steven M.

If a manufacturer incorporates compact geometry but doesn't reduce the number of sizes, there is no cost savings. Assuming the company was making bikes with level top tubes before switching to compact, they probably coughed up a substantial new investment in the compact designs, testing, tooling, training, marketing, etc. making the "savings" actually a loss (or investment depending on your perspective). |

It's going to be tough to avoid that when your website make statements like this- "Avoid aluminum frames at all costs." or " All touring bicycles have Chro-Moly steel frames for durability (aluminum frames won't stand up to the rigors of fully loaded touring)." Don't you wonder why all of the true touring bikes (admittedly there are few left) are still chro-moly, i.e. Trek, Fuji, Koga-Miyata, Bruce Gordon, etc. If even Trek sticks with steel, there is obviously a very good reason for it! And of course you are well aware of the reasons. The Trek web site sates (of the 520): "FRAME: Welded Cro-Moly built to endure the demands of fully loaded touring." And then later on you give all manner of anti-steel references (what a surprise that most come from steel-frame specialists), as well one from bikexchange.com that "No aluminum is going to hold up as well as steel." I do not give any anti-steel references. I could not find any such references. And of course there is no reason why a steel-frame specialist would make anti-steel comments. Just exactly what is it about a bicycle that can't take advantage of many of the useful aspects of aluminum, but an airplane can? Why aren't we worried about planes falling out of the sky? Oh no, we're back to the airplane analogy, and planes falling out of the sky! I think that the airplane analogy must be in the sales training materials of some bicycle manufacturers (come on, admit it, you wouldn't come up with this analogy on your own). It's a poor analogy, as most analogies usually are. See: http://www.anvilbikes.com/story.php?news_ID=16&catID=3 "When discussing aluminum, someone always brings up airplanes. Airplane design showcases what aluminum does best: acceptable strength and a low relative weight. But, aluminum's lack of a fatigue limit is one very good reason why there is stringent monitoring of dynamically or cyclically stressed aluminum structures." And you do recall the incident in Hawaii where an Aloha Airlines Boeing 737 suffered a structural failure. This was an inter-island plane, which had an abnormally high number of compression/decompressions, which fatigued the aluminum skin, causing stress cracks that propagated from rivet locations. Of course the solution here was not to make the airplane out of steel, it was to increase inspections, and limit the number of stress cycles. In short, we _are_ worried about airplanes falling out of the sky due to metal fatigue, and we monitor it closely now. You inspired me to add a section about the airplane analogy to my site. Opinions masquerading as fact are dangerous things. They certainly are. Almost as dangerous as marketing implicature masquerading as facts. This is not true; you're still claiming, despite evidence to the contrary, that a threadless headset costs less to incorporate on a bicycle than threaded. What evidence? Everything I've read on this subject indicates that the threadless headsets were adopted because they lower overall costs, because besides eliminating the manufacturing cost of threading, they allow one fork to be used on many different frame sizes, just as compact frames reduce the number of frame sizes that need to be manufactured. I know you're in a difficult position as a Trek-only shop, and that you feel obligated to defend the market direction taken by Trek. References to aluminum and titanium dogs were no doubt intended to be amusing, but are not. Steve Bicycle Recommendation Short List http://nordicgroup.us/bikerec |

The only valid reason I can think of for choosing steel for touring is that the frame can be repaired by just about anyone with a welding torch. The Trek web site sates (of the 520): "FRAME: Welded Cro-Moly built to endure the demands of fully loaded touring." A steel frame that's stiff enough to withstand loaded touring is going to be heavy, certainly heavier than a equally stiff aluminum frame. I suppose the manufacturers have learned that some extra weight is no big deal to the loaded touring customer. I have an aluminum Klein Navigator (a "true" touring bike) that weighs in at 23 lbs, and it handles the rigors of loaded touring just fine. -- terry morse Palo Alto, CA http://bike.terrymorse.com/ |
