Shimano's latest version of it's ever popular 105 groupset which will be seen on 2024 model year road bikes. Aimed at the mid market and keen amateur road cyclists, Shimano has updated the groupset with a number of features which keep it as the groupset of choice. Sam Gupta explores the similarities between this groupset and the electronic Di2 equivalent, as well as the updates and changes that make the groupset such a good choice.

Shimano has also launched a brand new 12-Speed GRX groupset. This update ushers 12 speed gearing across the entire GRX range of components, with updates to both 600 and 800 series of components. The gear ratios on offer has also been updated meaning the new parts really bring the fight to Sram. What do you make of both new groupsets from Shimano?
