Update to Shimano 7-speed hub gear page

Shimano Nexus 7-speed internal-gear hub with Rollerbrake

Our Shimano 7-speed hub page is now updated to fix the links which broke when Shimano redid its Web site. We have also added information about new models, and made a few improvements in the text. All of our pages about Shimano internal-gear hubs are now up to date.

We have updated our article about Sturmey-Archer 4, 5 and 7-speed internal-gear hubs to reflect changes in hub availability and new documentation.

Shimano 4-speed IG Hub Page Updated

Shimano Nexus 4-speed page updated — in our continuing quest to keep up to date with Shimano’s ever-changing Web site, we’ve updated the links and related information on Shimano Nexus 4-speed internal-gear hubs

Shimano 8-speed IG hub update

Sheldonbrown.com provides a forwarding page whenever we consolidate or move material. Not so Shimano, which broke all our links to its technical information. Sigh. We have just repaired our page on Shimano 8-speed internal-gear hubs.

Done with updating the Cyclecomputer/GPS Database…for now

We’re done updating the cyclecomputer and GPS database — this is the Internet’s most complete listing — except that it never is complete, as new models appear and old manuals are unearthed. Please feel free to send in information!

Cyclecomputer and GPS database update

Our cyclecomputer and GPS database is undergoing a major review. We’re not all done yet but we have fixed a number of bad links where manufacturers dropped support — thanks to the Internet Archive and our backup copies. And then there are the new models…many of them. We thought that cyclecomputers were passé, what with the advent of GPS, but this is still a strong product category. We found a number of new brand names as well.

Upgrading to index shifting

We have a major update to our page on upgrading older bicycles to index shifting. This can be done at a lower cost than you may expect, because there is usually no need to replace the rear wheel! Shifter choices, parts compatibility issues.

Securing your bicycle against theft

We have made major additions and updates to our article on locking and securing your bicycle against theft
