Nordenmark Adventure's Light map holder offers an alternative for those wanting to give it a try. For MTB orienteering, adventure racing, or bike touring. This option is light and simple at 170 grams and with only one clamp to the centre of the handlebars.
An update on an old classic. Nordenmark's Gold map board takes all that was best of both the Extreme and Classic models. Combines a light-weight frame with a quick-remove mount. At 400 grams, it's 100g lighter than the Extreme. It fits both regular and oversized handlebars. The map board holds maps up to 22.5cm by 30.5cm.
