Shimano 8-speed Internal-Gear Hubs

Posted on February 20, 2015 by John

Major revision to the page about Shimano 8-speed hubs:

Shimano Nexus hub

Shimano Nexus hub

— Added information on new hub models and fixed the many links which Shimano broke when it went to its new organization of technical Web pages.

— Linked to a number of documents Shimano abandoned. They’re available in the Internet Archive.

— Located other orphaned information where I could find it elsewhere on the Internet.

All in all, I’ve brought the information on each model of hub together in one place, to the degree possible with what I could find. Please let me know about errors and omissions.

Derailerless drivetrains

Posted on February 11, 2015 by John

New article, derailerless drivetrainswhite_hub250: How to choose frame and rear hub for a happy combination on a bicycle without derailers: a fixed gear, singlespeed, internal-gear hub, coaster brake bicycle — and how to adjust the chain tension. This article compiles information from the articles on fixed-gear and singlespeed bicycles. but adds to it and puts it in one place. Most issues with all derailerless drivetrains are the same, but there are important differences to note, there is new equipment to cover, and there are additional techniques to describe.
