What to Compare Before Buying
- Diameter: This seatpost is 25.4 mm, so the frame must match that size.
- Length: The post is 350 mm long, which affects saddle height adjustment range.
- Clamp setup: It is for saddles with a clamp, and the clamp itself is not included.
- Fit type: It is described for most old style bikes, so the frame and saddle setup need checking before ordering.
What Else You May Need
A saddle clamp may be needed if your current setup does not already have one, because it is not included with the seatpost.
Before You Decide
Confirm the 25.4 mm diameter, the 350 mm length and whether your saddle setup needs a separate clamp. Also check that the seatpost insertion will stay above the safe line mark.
