The Scott S20 is a high-performance bicycle known for its lightweight frame and excellent climbing capabilities. The frame design is similar to that of the S30, with notable enhancements in components that justify its higher price. One of the significant upgrades in the S20 includes the Shimano 105 crankset, which offers better performance and reliability than the Truvativ crank found on the S30. The hubs and rims on the S20 are also superior, providing less drag and better wheel stability compared to the Jalco rims on the S30. Additionally, the S20 is equipped with Shimano brakes that deliver enhanced stopping power compared to the Tektro brakes of the S30, making the S20 a safer option for riders. The overall weight of the bicycle is competitive, often around 7.2 kg with certain wheelset upgrades, contributing to its nimble handling and stiffness. While the ride may be a bit harsh on poor surfaces, it remains a solid choice for both casual and competitive cycling enthusiasts.
