The Concept Behind Silice Rohloff

Rider Fit & Sizing


This Silice Rohloff is a custom Size Large and is ideally suited for riders approximately 180–195 cm tall, depending on cockpit configuration and fit preferences.


In its current setup, the bike is equipped with a Thomson Off-Road drop bar, which features a relatively long reach. With this configuration, the bike will fit best riders around 190–195 cm who prefer a longer and more performance-oriented gravel position.


We can also adjust the cockpit to better suit slightly shorter riders. By swapping to a Salsa Cowchipper handlebar (68mm reach), and if needed swapping to a seatpost with 0mm offset, the bike becomes a very good fit for riders approximately 180–185 cm, offering a more compact and comfortable gravel riding position.


As always, we are happy to discuss fit in detail and make small setup adjustments to ensure the best possible match for the future owner.
