The groundbreaking article about fatigue-resistance testing of bicycle frames — the results surprised even the people doing the test — now in a much-improved new translation from the original German.
Bicycle frame fatigue-resistance testing
Category: Updates
Framebuilder information from Damon Rinard
Another Rinard article updated: his page of links to information, sources of materials and software for amateur frame builders.
Damon’s do-it-yourself carbon-fiber bicycle frame
Damon Rinard built a carbon-fiber bicycle frame in his garage! And we have just updated his pages describing how he did it, including sources for materials and tools. He points out that it’s actually much easier to build a carbon fiber frame than a steel frame.
Spocalc revised
The page for Damon Rinard’s spoke calculator has been revised, with an updated list of online spoke calculators, several comments and links, and better formatting. Now also includes links to spoke-calculator apps for iOS and Android smartphones!
SunTour Perfect, Pro-Compe and New Winner freewheels
New page on SunTour Perfect, Pro-Compe and New Winner freewheels. These are no longer made, but there are a lot of them around and they offer many options including the ability to work with older frames that have smaller overlocknut distance than current frames. We have information on choosing, maintaining and customizing these freewheels.
Cyclecomputer database
Our pages of cyclecomputer instructions have now been brought completely up to date, with links to user manuals for almost every make and model, including GPS. These pages are a unique resource.
Additions to the Gear Calculator
New crank lengths have been added to the Gear Calculator and Internal Gear Calculator, so they can calculate gain ratios for children’s bicycles with cranks down to 100 mm (less than 4 inches).
More hubs in cable-pull cribsheet
Added information on four hubs to the internal-gear hub cable pull cribsheet:
Shimano Alfine 11-speed
SRAM G9
Sturmey-Archer S3X
Sturmey-Archer ASC
Thanks to Jeff Meredith and Michael Wilson for the measurements!
Reorganization of headset tables
Our tables of headset sizes have been reorganized to make it easier to determine which headset can be made to fit which frame and fork. Fork crown race seats can be milled down and head tube race seats can be enlarged. The tables now are in order of head tube race seat size, as the frame is the more difficult and expensive to replace, followed by fork crown race seat size. The tables are used in the article on headsets and several other articles.
Shimano 4-speed hub gears
Expanded coverage of Shimano Nexus 4-speed hub gears — we now have rebuilding information, translated from manuals in German which are the only ones we could find online — complete instructions for both the freewheeling/Rollerbrake version and the coaster brake version. Thanks go to Patricia Morris for assistance with translation.
