Assos strives for peak comfort with new Mille FT Summer Bib Shorts GTO C2

Building on the ever-popular Cento shorts, the GTO is designed for the unique demands of long-distance riding.

It’s not often that a bib short comes with the claim to “destroy conventional short construction”, but as Assos’ new Mille GTO bib are being billed as the pinnacle of the Swiss brand’s total comfort line, perhaps the hyperbole can be forgiven.

So, what’s so different about these shorts? Firstly, there is the use of reversed stich lines and a reshaped chamois, with the intention of “eliminating friction and genital pressure whilst providing matchless muscle support”.

But alongside this, Assos has developed a new textile, dubbed “Losanga”, which the front panel of the shorts is constructed from and is designed to “eliminate pressure against sensitive areas”. The rest of the short is primarily made from Ossidia, which was first introduced with the Mille GTS bib shorts, and uses a “wrap-knit composition made with ultrathin yarns for muscle supporting compression.

In addition to that, the chamois benefits from Assos’ new Twin21 System and is made of three separate multi-density layers. The first, called “microShock”, is 11mm thick and makes up the foundation of the insert, designed to provide the majority of the shock absorption. Next is the “filterFoam”, which is a lower-density matrix foam designed to absorb microvibrations and minimise moisture buildup – thanks to its open cell structure. Finally, the “3D Waffle” sits against the skin and is designed to “increase breathability and eliminate excess weight”.

A staple of Assos’ attention to detail, the iconic “kukuPenthouse” has now evolved into the “sundeck superlight” and is designed to provide even better “support [to] the male anatomy and … maximum ventilation”.

The continuing fashion for shorts with longer lengths does mean it can be difficult for shorter, skinnier hipped, riders to find a set of bibs that don’t finishing irritatingly low on the knees. Happily, the GTO is available in two leg lengths, standard and long (+3cm), giving riders the choice of just how modest they wish to be.

Starting off riding mountain bikes on the South Downs way, he soon made the switch the road cycling. Now, he’s come full circle and is back out on the trails, although the flat bars have been swapped for the curly ones of a gravel bike.


Always looking for the next challenge, he’s Everested in under 12 hours and ridden the South Downs Double in sub 20. Although dabbling in racing off-road, on-road and virtually, to date his only significant achievement has been winning the National Single-Speed Cross-Country Mountain Bike Championships in 2019.
