Quick Summary

The FOMTOR 27.2 mm x 350 mm adjustable bicycle seatpost is a bike seat post for riders who need the stated size and an adjustable head. The product is positioned for mountain bikes, road bikes, BMX, and several other bike types named in the description.

Use the stated diameter and length as the first checks before choosing an offer. The adjustable head is a meaningful feature when seat angle matters for your setup.

Key Details

Detail Product information and buyer relevance
Brand FOMTOR. Brand identification helps separate this seatpost from similar-looking alternatives.
Product type Adjustable bicycle seatpost. This is the main part the buyer should match to the bike.
Diameter 27.2 mm. Check this against the bike’s seatpost size before buying.
Length 350 mm. Length matters for fit and insertion depth.
Head Adjustable head. This supports seat angle adjustment.
Intended bike types Mountain bike, road bike, BMX, downhill bike, track bike, MTB, DH. Compare this with the bike type and mounting setup you have.

What to Compare Before Buying

  • Diameter: Match the 27.2 mm size to the bike frame’s seatpost opening.
  • Length: Confirm that 350 mm suits the amount of post you need inside the frame and above it.
  • Seat angle adjustment: Check whether an adjustable head is the feature you want for your saddle setup.
  • Bike type: Compare your bike against the types named for this model.

Compatibility, Size and Fit

The main fit check is diameter. This seatpost is sized at 27.2 mm, so the bike must accept that size. The 350 mm length is another important check because seatpost length affects how much of the post is available for your riding position and frame insertion.

The description names mountain bikes, road bikes, BMX, downhill bikes, track bikes, MTB, and DH. Use those labels as a guide to the intended bike styles, but still confirm the size and mounting fit for your frame.

Before You Decide

Confirm the 27.2 mm diameter, the 350 mm length, and the adjustable head before choosing an offer. If your bike uses a different seatpost size, this version will not be the right match.

Additional Fit Checks

Beyond diameter and overall length, confirm the frame’s minimum seatpost insertion requirement and whether the post’s head clamp accepts your saddle rails. A listed bike style alone does not establish fit for a particular frame and saddle.
