Our hardtail tandem Cellecs is ideal for long-distance touring in mountain and gravel terrains. The 120mm front fork ensures a good suspension at the front while its rigid rear triangle maximizes power transfer for smooth and fast rides, making it perfect for both off-road trails and touring.
At Campmajó, every tandem is fully customizable—from geometry and components to paintwork. Build your perfect ride with premium components from our trusted partners, including FSA, DT Swiss, SRAM, and SQ Lab, among others.
In all our rigid models we offer the option of a low rear step through, free of charge. This is designed to make the tandem fully accessible and comfortable.
