- Seatpost length: The stated length is 350 mm, which matters for insertion depth and saddle height setup.
- Suspension travel: The seatpost has 35 mm of travel, so compare that amount with the level of movement you want at the saddle.
- Adjustment range: Swappable elastomers, springs and preload adjustment affect the feel, so check whether that style of setup suits your preference.
- Bike type: It is positioned for gravel or road bikes, so make sure it matches the bike you plan to fit it to.
Compatibility, Size and Fit
This seatpost is a 27.2 mm x 350 mm model. That makes size the main check before buying, because the post must suit the frame’s seatpost diameter and still allow the saddle height you need.
The constant saddle angle through travel is part of the design, but the main practical decision is whether the 27.2 mm size and 350 mm length suit the frame and riding position.
What Else You May Need
To use this seatpost, you need a bike frame that accepts a 27.2 mm seatpost. If the frame takes a different size, a different version is needed.
Before You Decide
Check the frame’s seatpost size, the 350 mm length and whether the 35 mm travel suits the ride feel you want. The swappable elastomers, springs and preload adjustment are part of the setup, so confirm that this configuration matches your preferred saddle feel before choosing an offer.
