# Bicycle Mechanics - Analysis of Spoke Tension and Other Forces in a Bicycle Wheels

Bikeforums.net is a forum about nothing but bikes. Our community can help you find information about hard-to-find and localized information like bicycle tours, specialties like where in your area to have your recumbent bike serviced, or what are the best bicycle tires and seats for the activities you use your bike for.

More than you may ever need to know about Spoke Tension.....

Conclusion: Not much difference between 2X, 3X and 4X.....

In brief, the conclusion of the study is:

"A typical bicycle wheel is a robust structure with very good fatigue life. Theoretically, the hub/spoke/rim system will work in bicycling applications with very little problems."

interesting paper...
wish he would have done an analisys on a rear wheel with the radial spokes on the drive side and the 2/3/4X pattern on the non-drive side.

I find it surprising that 2x is stiffer than 3x and 4x. It makes sense, but I didn't think it would be a matter of building a wheel with durability at the expense of stiffness (lateral stiffness).

Me to, I haven't used math like that in 45 years.

For those whohave not had enough with the Duke paper or Jobst Brandt, there's also a book being sold on Ebay, The Spoken Wheel, written by an aerospace engineer cyclist. He derives formulas and applies them to a huge variety of configurations. \$12.00 BIN, and there are a few copies.

I think it's great, but well, you know, engineers ....

Anything would be better than the book
