I recently emailed them and asked about their chamois differences, and this is the reply I got, with a nice pic for comparison, you may find it useful.steveadore wrote: ↑Sun Jul 18, 2021 11:31 pmIf you disregard the price, fabric, and constructions differences, which one would you choose between the Gregarius Ultra and the Dottore (X) purely based on comfort and long-term durability (both for road and MTB)? I have the Ultras and quite like them and I wonder if I should buy a second pair or upgrade to the Dottore. I don't race and the compression on the Ultras is plenty enough for me. The Dottore is tempting, but the older L1 version lacks the Dyneema C Cup interface of the Ultra, and the X version, is about 40% more expensive (but it has the Dyneema panel). I'm not sure I would like the straps of the Dottore though (I'm quite happy with those on the Ultra, where the front is similar to Assos S7). And some have mentioned that the chamois pad on the Dottore is thinner than the Ultra. Lastly, someone also complained about the Dottore fabric pilling after a few hundred kms (I can't remember if it was the X version with Dyneema or the L1 without). Any comparisons would be really appreciated. Thanks.
"All our bib shorts have similar chamois regarding the thickness and only differ in a few millimeters. Our newest chamois and regarding thickness, also the thickest is included in the Gregarius Ultra and the Gregarius Cargo. It is called anatomic, is super molded and adapts to the body and also has a better breathability (then the one we are using for the Dottore) due to some perforation. The UNIQUE bibs do have a different chamois as well, this is the most breathable, because it has a different fabric in the front, which guarantees the most breathability. Also the Dottore and the Dottore X differ in the chamois. The Dottore X and Dottore have almost the same chamois, but the chamois from the Dottore X is sued and from the Dottore not. Also the not sued one is used for all the tights.
On the left upper corner you can see the chamois we use for the Dottore classic and all the tights. The right upper corner is the chamois from the Dottore X. The left corner below is the UNIQUE chamois and the right corner below is the newest anatomic, which is used in the Gregarius cargo and Gregarius Ultra and which I would recommend for your special needs." Bike24.com has a sale on some of the shorts now btw.
