Sheldon’s Journal and an anniversary
Sheldon started keeping an online journal on November 8, 1998. He posted synopses of his thoughts and activities, comments on books, films, TV shows, and music both live and recorded. He wrote his final note on the day he died, February 4, 2008, 9 years ago. The first page, from 1998, links back to a “1975 Retrospective,” which links in turn to a “1971 Retrospective.’
He used the photo here in the 1971 retrospective — a selfie — from 1971. Sheldon was way ahead of the crowd with selfies!
Update on direct-pull brakes (“V brakes”)
Sheldonbrown.com makes a point of providing information which is hard to find elsewhere and which will help keep older bicycles working like new — or better. Shimano Parallel-Push V-brakes have a very nice feature in that the brake shoes approach the rim squarely rather than rotating, with the risk of damaging the tire or diving under the rim. Reader Paul Rintoule has kindly sent in information on how to refurbish Shimano parallel-push direct-pull brakes to stop them from squealing, even though Shimano parts kits are getting very hard to find. This information has now been added to our page about direct-pull brakes.
Raleigh Twenty page expanded
Our page about Raleigh Twenty bicycles has been expanded with two new sections, about the hinge and the rear rack. Find out why the humble and disdained Pletscher rear rack works great on a Twenty, and how to make a replacement for a missing hinge key.
