Can I customize the components on a Cervelo Aspero without voiding the warranty or affecting the bikes performance. Specifically, Im looking to upgrade the crankset, chainrings, and cassette to better suit my riding style, but Ive heard mixed reviews about the compatibility of aftermarket components with the Asperos frame design. What are the limitations and potential pitfalls of customizing this bike, and are there any specific components that are known to work well with the Asperos unique design. Ive seen some owners swap out the stock wheels for lighter, more aerodynamic options, but Im skeptical about the benefits of doing so, especially considering the added cost. What are the real-world benefits of upgrading the wheels on the Aspero, and are there any other components that can provide a similar performance boost without breaking the bank. Im also curious to know if anyone has successfully installed a different groupset, such as Shimano or SRAM, on their Aspero, and what kind of modifications were required to make it work seamlessly.
