What to Compare Before Buying
- Seat tube diameter: Match 27.2 mm, 30.9 mm or 31.6 mm to the frame opening on your bike.
- Length: Compare 350 mm and 400 mm against the height and position you need.
- Saddle fitting: Check whether the adjustable head works with your saddle rails and setup.
- Insertion depth: The safety line mark shows the minimum insertion point, so confirm the frame allows enough seatpost to remain inside.
Compatibility, Size and Fit
This seatpost is intended for bikes including road bikes, mountain bikes, BMX, fixed gear bikes, downhill bicycles and rail bikes. The key fit checks are the seat tube diameter and the length you choose. A 27.2 mm post will not fit the same frame opening as a 30.9 mm or 31.6 mm post, so measure carefully before ordering.
What Else You May Need
You need a frame that accepts the chosen seatpost diameter and allows enough insertion depth to stay above the minimum safety line. The saddle must also be compatible with the adjustable head fitting.
Before You Decide
Confirm the exact diameter and length before choosing an offer, then check that the frame can take the seatpost with the minimum insertion line respected. Make sure the adjustable head suits your saddle setup and intended bike type.
