ProsNeat and functional

This is the perfect solution to adding bottle cages to a frame without bosses. As long as the frame has round profiled seat or down tubes this works really well . It is similar to a front mech clamp . Neat hinges . Stainless steel bolts . Added to my road going fixie frame .

Hello,

Does each item come with 2 adapters (as shown in the image) or one?

Thank you.

Hi
Thank you for your enquiry. This item is sold as a pair so you will receive two adapters should you order.
