This is a holder for attaching a number plate to the seat post of a road bike or MTB.
Please choose from two types: for aero posts (V-shape) and for round seat posts (O-shape/D-shape), depending on the shape of your seat post.
It allows for smart attachment of number plates during cycling events such as road races, MTB races, triathlons, hill climbs, and enduros.
While zip ties can cause distortion or flapping, using a dedicated holder allows for stress-free number plate attachment.
It looks good in photos and does not interfere with pedaling or other movements.
Please select according to the cross-sectional shape of your bike's seat post.
For aero seat posts with a D-shape, the type for round seat posts will fit.
The weight is designed to be light, around 10-15g, so we believe you can use it without worrying about added weight even in hill climb races.
