My S-Type with extended seatpost fits in that case without removing the seatpost (I do have to remove the saddle) so I'm curious as to whether the extended seatpost not fitting is a model-specific thing.

I do find the bike is a bit of a squeeze in the short dimension (side to side on the upright bike) and the case 'top' has some give in that direction; I (once) found a brake cable had been crushed between fork and stem, which probably means it had something very heavy stacked on top. I rotate my Ergon grips so they lie 'flat' in transit.

Otherwise it's slowly getting more and more battered and the latches are finicky, but has basically protected the bike over dozens of flights.

And I think I may have Ozonation's definition of "cycling enthusiast" as my signature.
