In this episode of Nerd Alert, we discuss the merits of Ratio Technology’s new 12-speed conversion kit for SRAM 11-speed levers, as well as the pros and cons of wireless technology for Shimano’s next-generation Dura-Ace Di2 groupset. We then have a chat with the folks at Cadex and discuss the challenges of positioning a high-end “in-house” brand against established third-party aftermarket labels. Finally, we finish off with another round of “Ask a Mechanic”. Moral of the story: don’t take mechanical advice from Caley.
