The cycling industry has seen major technological advancements in 2025, with significant developments across various sectors. Larger wheels, specifically 32″ for mountain and gravel bikes, have moved from niche to mainstream, with brands like BMC testing prototypes in competitive settings. Despite initial resistance, the UCI is considering allowing this new wheel size in competitive racing, and full-suspension models are expected to debut soon.
Electronic drivetrains continue to dominate, with SRAM, Shimano, and Campagnolo all launching new products. SRAM has expanded its offerings with affordable versions of its high-end drivetrains, while Shimano has introduced fully wireless electronic systems for mountain and gravel bikes. Campagnolo has also entered the electronic space with new groupsets. Interestingly, SRAM has also released new mechanical drivetrains, signaling a continued interest in cable-actuated systems.
In road cycling, the UCI has introduced new regulations to limit aerodynamic enhancements, mandating minimum handlebar widths to enhance rider safety. This move marks a significant shift in the focus on aerodynamics in competitive cycling.
