- Seat tube fit: Confirm the receiving seat tube size on the frame and compare it with the size you need from the set.
- Length: The stated 60 mm length may matter where insertion depth or exposed post length is important.
- Material preference: The adapter is aluminium alloy, so buyers who need the same material should check that this suits their setup.
Compatibility, Size and Fit
This set is for bikes that need a seat post size conversion between 27.2 mm and one of the listed larger diameters. The important check is the exact seat post and seat tube size on the bike, because the wrong diameter will not give a correct fit.
It is relevant to road bikes and mountain bikes MTB, but the size match matters more than the bike category itself.
Before You Decide
Confirm the exact seat post diameter, the required adapter size and the 60 mm length before choosing an offer. If the bike uses a different diameter, a different adapter size will be needed.
