Shimano’s Dura-Ace R9300 surfaces as 13-speed, semi-wireless at the Vuelta

Cyclingnews reports a prototype Shimano Dura-Ace R9300 groupset has been spotted on Alpecin-Premier Tech bikes at stage 1 of La Vuelta a España. The photos indicate a 13-speed rear cassette and a redesigned shifter with a protruding thumb button, with a semi-wireless setup (shifters wirelessly communicate to derailleurs via a battery in the frame) rather than a fully wireless system. The leak suggests a new freehub body will be required, alloy cranks similar to current designs, and potential 1x compatibility, though exact cog sizes and final specs remain unconfirmed.

Hammerhead Karoo 3 Hits Year‑Low Price During Prime Day Deal

Amazon UK has slashed the Hammerhead Karoo 3 to £303.49 for Prime Day, the best price of the year for Cyclingnews’ top-rated navigation computer. The Karoo 3 is praised for its smartphones-style touchscreen and strong navigation, and it’s positioned as a compelling competitor to Garmin’s Edge 1050 (which is discounted to around £633–£680). The Prime Day deal is UK‑only and limited by stock, with the sale running as part of Amazon’s four‑day event from June 23–26. Deals affiliates noting the price may not last long and prices can vary by retailer.
