Seido is the off-road brand of the Cologne-based bicycle and component manufacturer Bombtrack. The Seido Tab 3.8 mm handlebar tape was specifically developed for gravel riders who want not only good cushioning but also good grip. The surface is made of microfiber, which has been supplemented with grippy silicone.
The thickness is 3.8 mm, the length 230 cm - important for gravel handlebars, which are often significantly wider than "normal" road handlebars. The silicone tabs make the tape very grippy both with gloves and with bare hands, whether in wet or dry conditions.
