Stolen Calibre Bikes: UK Frame-Number Check (Free)
Last updated
Quick answer
Calibre frame numbers are stamped on the underside of the bottom bracket. Calibre is the Go Outdoors house brand, known for value mountain bikes like the Bossnut, so it has a strong used following and theft profile. Run the number through Cyclesite's free lookup for an instant UK check against a stolen-bike registry and rider-filed theft reports.
Where Calibre stamps the frame number
On the underside of the bottom bracket shell on the vast majority of Calibre mountain bikes. As a Go Outdoors own brand, the original Go Outdoors receipt is the cleanest proof of ownership, and it should match the stamped frame number.
Calibre on the UK used market
Calibre built its reputation on high-value mountain bikes such as the Bossnut and Line, which sell strongly second-hand and are a recognised theft target for the spec they offer at the price. Confirm the frame number against the Go Outdoors paperwork before buying.
