# Shimano cycling equipment product launches > Live situation record from CLSTR: https://clstr.news/situations/shimano-cycling-equipment-product-launches > Updated: 2026-09-26T13:29:41.000Z. Sources: 14. Developments: 4. Shimano has introduced several technical updates to its cycling equipment, beginning with the DYNALAST 2.0 shoe platform. Utilizing biomechanical research and 3D foot scans, this platform offers Narrow, Standard, and Wide options to improve stability and allow for natural toe expansion. Following the footwear update, Shimano unveiled the SPD-SLR pedal and cleat system, the first major change to its SPD-SL road standard in approximately 23 to 24 years. The new ecosystem, which includes Dura-Ace (PD-R9300) and Ultegra (PD-R8200) options, features a reduced stack height, lighter cleats, and a wider catch zone. The flagship Dura-Ace model utilizes a new axle design with wide bearings intended to increase stiffness by 11%. Notably, the system features a narrower engagement angle of 10.5 degrees, compared to the previous 15.5 degrees. The SPD-SLR system is not backward compatible with existing SPD-SL components, a change highlighted during the Paris-Roubaix race when Mathieu Van Der Poel was unable to clip into a teammate’s bike due to the differing systems. Expanding on these updates, Shimano launched the RC910 and RC810 cycling shoes, which incorporate the redesigned Dynalast 2.0 last. The design aims to improve pedaling efficiency and reduce forefoot pressure through a wider toe box. In the standard fit, forefoot space increases by approximately 4%, while the wide fit expands space by about 7% compared to previous wide models. The flagship S-Phyre RC910 features a carbon fiber heel shell with an ‘Anti-Twist Stabilization’ system and a Carbon Hollow Core midsole, while the RC810 provides a more accessible tier with a slightly less rigid sole. ## Claims - Shimano has released new SPD-SLR pedal systems at both Dura-Ace and Ultegra levels.
