Calibre
Calibre is the in-house brand for outdoor sports giant Go Outdoors. Its bikes are known for their impressive value for money and intelligent spec choices.
Calibre’s award-winning Bossnut shook the industry in 2015, showing just what a sub-£1,000 full-sus bike could do. Since then the brand has continued to push the boundaries, making high-quality frames with decent components more accessible.
Calibre's bikes mainly fall within the realms of mountain, adventure and road, and we’ve reviewed many of them very favourably.
