Mountain Bike Magazine is a free subscription with IMBA membership with it's parent magazine Bicycling Magazine. I don't know if MBM is available on news stands these days. For most years MBM seemed to be written by road riders unfamiliar with mountain biking with only novice knowledge revealed in articles. Around Y2K the quality of expertize was raised to heights no other US magazine had while the staff was lead by for 2 or 3 years by Zapada Espinoza, but Zap was fired in 2003 for some unapparent reason, maybe his unusual appearance didn't fit in the Bicycling Magazine boardroom. But in the last year the quality of technical articles has risen again. Maybe there is an experienced mountain biker heading up the staff again.
In the current April 2010 issue is an article on carbon fiber. The most informative I've ever read. It is also on the MBM web site broken out in a number of more lengthy articles than the magazine carried. Click on this link, or copy and paste this to you browser: http://mountainbike.com/carbon (it routes to a page with a series of photos of Giant bicycles carbon fiber production).
On that page in the list of "RELATED" articles is one called "Black Magic: The Truth about Carbon Fiber" where Ibis carbon fiber frame design engineer Colin Hughes is quoted briefly on page 5 of 6. Link: http://www.bicycling.com/article/0,6...1967-1,00.html
There is also an article called "The High-Modulus Carbon Myth Debunked" stating that the term "Ultra High Modulus" is falsely used by some manufacturers. Ibis has posted that there is use of some Ultra High Modulus in the Mojo SL to increase stiffness but most of the fiber is more common High Modulus for durability. Ibis may not reveal all their secrets, but they do not lie, as implied by the article.
