As one of the most noteworthy releases of 2018, Rotor's 13-speed hydraulic groupset certainly wowed us with its innovative features and exceptionally tidy execution.
Jack reviewed the 1x13 groupset earlier this year, awarding it an impressive four out of five stars, thanks to Rotor's mission to add more useable gear ratios, its modular design and top performance.
We caught up with Rotor's Lori Barrett at Sea Otter 2019 to talk us through some of the more techy features of the novel groupset.
