GTO marks the pinnacle of the Assos Total Comfort MILLE GT line - spiritual successor to the iconic CENTO and Campionissimo Bib Shorts. It features the plushest, most responsive, and breathable ASSOS insert to date, wrapped in new frictionless, wrinkle-free paneling. The GTO has two leg lengths: Standard and Long (+3cm vs standard).

With large-muscle support, friction, and excessive pressure remaining critical issues on long-duration rides, GTO destroys conventional bib short construction formulas. Assos reversed stitch lines and radically reshaped the insert to eliminate friction and genital pressure while providing matchless muscle support with tapered, wrinkle-free leg panels that mirror your personal physique.

Note: This listing is for the long version of the GTO bibs - 3cm longer than standard.


  • RollBar one-piece Butterfly panel for proven stability
  • Two lengths: standard and long (3cm of additional leg coverage)
  • ZeroWaist provides smooth transition between body and fabric
  • SuperFlat X-FRAME elastic material supports and delivers limited vertical stretch in the rear
  • SkinGrip Finish raw cut edge with minimal silicone treatment secures shorts without any excessive pressure
  • Mille GTO C2 Insert for maximum comfort and ventilation

Assos MILLE GT Summer Bib Shorts GTO C2 (Black Series) (Long) (M)
Paid $350 for these shorts. Wore them for two seasons. Fewer than 1,000 miles per season on the shorts. The front seam below the belly then came apart. Assos and the vendor (Performance Bike) say it is no longer under warranty and cannot be repaired. The best they can offer is $50 off a full priced replacement. I’ve been wearing Assos bibs exclusively for over 15 years. This is not the quality of product or level of service I expect. I will think twice before purchasing another Assos product.

Measurement Guide:

  • To determine the best size measure the waist, hips, and height and take the average
  • If in doubt, Assos recommends sizing up
  • Waist- Measure the circumference around the narrowest part of the waist
  • Hips- Measure the circumference around the fullest part of the hips
  • Height- Measure height from head to toe
