A quick summary of the latest Bike Tech:
This month's issue of Bike Tech (April, 1984, V.3, No.2)
contains articles on Rim Design (8 pages) complete
with strength and rigidity measurements for 12 popular
alloy rims. A further article discusses how resiliency
of rims is important (i.e. their ability to yield to
excessive load, yet recover). Overall the articles
probably raise as many questions as they answer, but
they are informative for those interested in bicycle
technology.
An additional article covers frame geometry for rough
trails, a discussion of the design decisions to be made
when building a frame for trail use. As an example,
shorter chainstays put more weight on the rear wheel
producing better traction.
The letters section continues the discussions on
particle blasting of frames, Ed Scotts new brakes, and
destructive frame testing; all subjects of earlier articles.
Bike Tech, for those of you who are not familiar with it, is a
small (about 16 pages, small print, no ads) technical journal
on bicycle engineering put out by Bicycling. Sample copies
and subscription info from Bike Tech, Emmaus, Pa. 18049'
With the usual disclaimers, I am but an interested reader/subscriber
of the journal.
