What to Compare Before Buying
- Seat tube diameter: This post is 27.2 mm, so the frame must match that size.
- Post length: The stated length is 350 mm, which affects fit and adjustment range.
- Offset: The 0 mm offset is a key setup choice for saddle position.
- Insertion depth: The minimum insertion length is 90 mm, so check frame clearance before purchase.
- Saddle adjustment: The dual-bolt micro-adjust cradle is the main setup feature to compare if fine positioning matters.
What Else You May Need
You will need a compatible bike frame that accepts a 27.2 mm seatpost and can meet the 90 mm minimum insertion length.
Before You Decide
Confirm the 27.2 mm size, 350 mm length and 0 mm offset before choosing an offer. Also check that your frame can accept the stated 90 mm minimum insertion length, since that is central to fit.
Compatibility, Size and Fit
Also check that the seatpost cradle accepts your saddle’s rail type. The listed size, length and offset do not establish compatibility with every saddle rail.
