When ‘King’ Kenny Roberts started the trend for drag­ging a knee, kneesliders were lit­tle more than bits of old rub­ber.

Nowa­days, how­ever, you can get leather or plas­tic slid­ers in all shapes, sizes and de­signs. You can even spec­ify ex­trathick wet weather ones and dif­fer­ent com­pounds to suit a track’s abra­sive­ness.

Plas­tic kneesliders are made in a va­ri­ety of ways, but the most com­mon is in­jec­tion mould­ing. Some man­u­fac­tur­ers, if their logo is set into the slider, have it made in plas­tic be­fore­hand to the height of the slider and placed in a slider-shaped mould. TPU (ther­mo­plas­tic polyurethane) is then in­jected around this to form a solid puck. By cre­at­ing the logo be­fore­hand, man­u­fac­tur­ers en­sure their logo will still show when the slider is worn (like a stick of Black­pool rock). In­ter­est­ingly, rac­ers of­ten have the Vel­cro the other way to road rid­ers with the hooks on their leathers and the fab­ric on the slider’s back to make chang­ing them quicker and eas­ier.
