Anyone know of a book that explains all this industry jargin in terms of sound Mechanical Engineering principals. I have an ME degree and want to understand all the BS these bike companies talk about in terms of physics/dynamics.
Thanks. |

One of the magazines had a good article a few months back that talked about a lot of the technical terminology but I don't remember which one it is. Most of the engineering terms relating to suspension and material science are fairly standard. |

Apr 2, 2002 3:53 PM | | The closest thing you're likely to find is a book on motorcycle design. There are several of them. I have Motorcycle Design and Technology by Gaetano Cocco. It's interesting but badly translated from the Italian and full of obvious mistakes. Tony Foale is coming out with a revised version of an old book. It's good that it's revised because a sample passage from the old one on his website had a mistake in it. His site is www.tonyfoale.com.
Some problems I've found with all the books I've looked at are they don't deal with the constantly varying force that characterizes pedalling. They give formulas for steady state acceleration that don't apply to pedalling, although they work for braking. Also I've not found any treatment of chain torque or brake torque on a four bar linkage. |

Apr 2, 2002 5:10 PM | | So if there are any ME bike designers out there with decent technical writting skills you should write this book. I am so sick of hearing BS explainations from variuos people and bike companies with way too many buzz-words. Sombody clear the air please. |

Apr 2, 2002 10:53 PM | | you should be able to tell what's BS and what's not. I'm graduating this June with an ME degree and can tell what isn't kosher 95% of the time. Do a little research and find out the truth. Practically everything you read there lies a marketing person beind it. So, a book would be nice, but it doesn't cover all. Be smarter than that, think and figure it out.

We have the bicycle industry to blame for the no-greasing crank tapers myth for example (pretty much every OTHER industry they teach people that when joining metal surfaces, especially dissimilar alloy machined surfaces, under pressure (whether threaded or in the case of cranks, interference fit), that lubrication of ALL surfaces making contact is needed to get proper torque measurements. Yet in the bike industry these basic mechanical engineering laws get thrown out the window and they invent all sorts of new explanations on how cranks (and ONLY in the bike industry) are assembled to bottom brackets. My favourite is that friction holds the parts together, and that grease causes the TAPERED crank to slide too far up a TAPERED BB spindle (with a 2 degree taper at that) under normal bolt torque on the crank bolts. Somehow elastic deformation of the metal surfaces (which is the principal actually at work) got replaced by surface friction to explain how the parts are held together.
There are also all the morons who throw out words like melt-forging (another term pretty much exclusive to bikes, since its either casting, hot forging, or cold forging!), near-net forging, damping vs dampening (depending on which school of suspension terminology you prefer) and so on. |
