We at Synergy Cycle believe that the Cento bib-short represents the highest price-value for a cycling short designed for cyclists who spend a lot of time on their bike.  The comfort and durability that they propose is unlike anything else available in the market for the price.  If you ride more than 4000kms/year, you're wasting your time and money with other bib-shorts.
