This product is for our previous models of Fender Blenders with round seat posts. If you have one of our older models, we upgraded our seat posts a few times. The older model does not have a groove and used a clamp with a 34.9mm inside diameter, while the new round seat post has an anti-rotation groove and uses a clamp with a 38.6mm inside diameter.

In order to figure out which style is compatible with your bike, you will need to look at the area beneath the clamp on the frame.

Does it have a screw hole?


YES screw hole = newer style



NO screw hole = older style

Is your Fender Blender Pro seatpost sliding poorly?
