Shimano Road Bike Groupsets

Shimano road bike groupsets (also known as Gruppo’s) work as a group of components which integrate perfectly to control today’s modern road bikes. Trickle down technology has led to lower range groups, Tiagra and 105, utilising the same technologies and materials as previous models of Ultegra and Dura Ace. Merlin allows you to choose custom options for your groupset, such as crank length and cassette ratio
