Cannondale HollowGram Seatpost

This seatpost has a 31.6mm diameter and a 400mm length. You should verify that your frame is designed for a 31.6mm post before purchasing, as this is a standard size but not universal across all mountain bike frames.

Yes, the clamp design is versatile and fully compatible with both round and oval rails, including carbon and metal options. You can confidently mount your preferred saddle without worrying about rail compatibility.

This model provides 170mm of travel, which is generous for cross-country riding. This range allows for significant saddle clearance on technical descents while keeping the post lightweight.

The reflective rear decal is a subtle but effective safety feature for low-light conditions. While it doesn't replace a dedicated rear light, it does provide an extra layer of passive visibility when headlights hit it from behind.

While engineered for cross-country performance, its robust full-carbon construction is built to handle the demands of aggressive descents and technical terrain. It balances weight savings with the structural integrity needed for varied trail use.
