Zoom Suspension Seat Tube for Mountain Bike, Aluminum Alloy Seat Post
Meet the Zoom Suspension Seat Tube for Mountain Bikes — a high-strength aluminum alloy seat post with an internal shock absorption system designed to smooth your ride on rough trails. The outer tube uses durable aluminum alloy, delivering reliable performance ride after ride. A small, precise screw beneath the seat tube lets you subtly adjust stroke rebound speed, so you can dial in the feel to match your weight and riding style. Compatible with 27.2 mm or 31.6 mm frames and available in a 350 mm length, this seat post also includes a variable diameter sleeve to fit frames with diameters of 28.6, 30, 30.4, 30.8 and 33.9 mm. Note: size and weight are measured manually and may vary slightly.
Benefits & Tips
- Internal suspension absorbs bumps for a smoother ride and reduced saddle discomfort on rough MTB trails.
- Use the rebound adjustment screw to fine-tune stroke feel — slower rebound for a cushier descent, faster rebound for lively pedaling.
- Variable diameter sleeve broadens compatibility, letting the seat post fit multiple frame diameters (28.6–33.9 mm) for versatile mountain setups.
