Specialized Road Kit (SWAT) compatibility


Is someone here familiar with the Specialized SWAT (road kit)? I am wondering if it is compatible to my Shiv TT bike (2017).
The original ‘Fuel Cell’ fitted near the bottom of the frame is missing the top part and I’m looking for a good replacement.

The follow-up question I’ve got about the SWAT Road Kit is what the maximum length of a tires’ valve can be to still fit within the kit.

Thanks in advance!
