- Use case: The product is described for mountain road bikes, MTB and BMX, so confirm that this type matches your bike.
Compatibility, Size and Fit
This seatpost is meant for frames with a 31.6 mm seat post hole. That diameter is the main compatibility check, since a mismatch would prevent correct installation. The 300 mm length also affects how much adjustment room you have after the post is inserted.
Because it is a saddle tube replacement, buyers should compare the clamp style and saddle hardware on their bike before choosing an offer.
Before You Decide
Confirm the 31.6 mm diameter, the 300 mm length and the clamp style before choosing an offer. If your frame uses a different seat post size, this seatpost will not be the right match.
