Did some checking and found nothing beyond 38.

BITD it seemed standard for manufacturers to fit 38's on everything...even machines with 65cm frames!

Tip -

if you reach a point where you have several choices i would take Philippe over AVA and PIVO for their strength.

some AVA & PIVO models lack adequate reinforcement in their centres.

shall keep an eye out for you and post here if anything interesting encountered.
