Fits Brompton handlebar stems which are roughly 35mm diameter. Perfectly holds a Camelbak bottle or any other drinks bottle that’s 73mm diameter. I have ridden with mine for over 20 miles and it works great! Can be positioned anywhere above the bend in the handlebar stem. Easy to install with just two fasteners (2.5mm hex key). 3D printed in durable PETG plastic and also comes with marine grade stainless steel fasteners to ensure no rust! Postage via Evri to UK mainland or Global Shipping Program. Please check out my other 3D printed Brompton / sea fishing parts. Thanks for looking
