Guide to Top Stay Length

Which Top Stay is right for me?

Short Top Stay – Use the below as a general guide:

  • with regular (or larger) bike frame sizes (>54cm)
  • 100mm or more visible seat post
  • no dropper post fitted to your bike
  • riders who want maximum aero benefits

Long top Stay – For riders who feel they will need a little extra space behind the saddle when using the AP20 Trunk tp Bag:

  • for smaller bike frame sizes (<54cm)
  • less than 100mm visible seat post
  • if you have a dropped post fitted to your bike
  • saddle positioned far back on its rails
  • if you plan to carry items on top of the bag (e.g sleep mat strapped to the bag)
