Using the Shotgun Pro seat is easy. First, make sure your bike has a standard 1 1/8 - inch steerer and there's 10mm of clearance under the stem. If your bike's stem is shorter than 50mm, you may need more under - stem clearance. Install the spacers provided, which replace 10mm of standard steerer spacers. When it comes to the seat post, ensure there's 14mm of available space as it fits dropper posts and common sizes. To attach or remove the seat, it's lightning fast. Remember, the adaptors for Trek Knock Block and Scott Syncros headsets are sold separately, and the seat won't work with bikes that have a quill stem. For maintenance, keep it clean after rides and check the attachments regularly to make sure they're tight and in good condition.
