Seat Strut Clamps work hard to bring your bike several benefits so that you can sit back and enjoy! Many people get them just for the peace and quiet they provide, but the greatest advantage to Seat Strut Clamps is the dramatically stiffer seat support. Since there's no play in the tubes after you've installed these clamps, the back of your seat will be much stiffer, improving your bike's handling and often noticeably improving your pedal efficiency at the same time!
These clamps are compatible with any bike that uses telescoping tubes that are either 1/2 to 5/8 inch, 5/8 to 3/4 inch, or 3/4 to 7/8 inch.
Bikes/Trikes with 1/2 into 5/8 Tubes: Bacchetta, Burley, Sun, Longbikes, some older Rans models
Bikes/Trikes with 5/8 into 3/4 Tubes: Newer Rans models, WizWheelz/TerraTrike pre 2012 models, and Barcrofts
Bikes/Trikes with 3/4 into 7/8 Tubes: 2012 and newer TerraTrikes and other larger rear strut machines
It does not matter whether the larger or smaller tube is on the top or the bottom. The clamps work either way.
