THE NEW i:SY XXL E5 ZR F Di2 - SHIMANO'S electronic e-bike gear shift is not only fast and precise – it can also be switched from manual to automatic when desired. Thanks to its integrated servo technology, the Di2 decreases the motor peak load, enabling the Nexus E5 gear hub to be used with a full torque on the Bosch Performance Line CX. Like all other i:SY models the E5 ZR F Di2 model also impresses with cross-series fittings such as disc brakes. The i:SY XXL was primarily developed for tall cyclists (up to 210 cm tall). All parameters have been adjusted accordingly and thus designed to withstand a greater stress load. The total permitted weight is 180 kilograms. In addition to height adjustment, the SpeedLifter Twist also allows the handlebars to be turned 90 degrees with no need for any tools. The pedals can also be folded in with a single click, as with all i:SY models.
