Shimano launches 12-speed mechanical GRX and 105 groupsets

In this episode, senior technical writer, Simon von Bromley, is joined by road and gravel presenter, Liam Cahill and Ashley Quinlan, senior technical editor, to discuss the two big launches from Shimano – GRX RX810 and 105 R7100. Having attended the press camp in Portland, OR, USA, Liam shares all the details plus his impressions of how the new 12-speed GRX performs. In the final section, the trio dissect 105 R7100 – Shimano’s first 12-speed mechanical road groupset – and whether there’s enough new tech to justify anyone with 11-speed 105 R7000 upgrading.
