Can a dropper seatpost be effectively utilized on a mountain bike with a steep seat tube angle, and if so, what are the potential drawbacks and benefits compared to a traditional seatpost? Would a dropper posts ability to lower the saddle height compromise the bikes overall handling and stability, particularly in situations where a more upright riding position is desirable, such as technical climbs or slow-speed maneuvers? Are there any specific frame design considerations or component compatibility issues that need to be taken into account when installing a dropper post on a mountain bike, and how might these impact the overall performance and functionality of the bike?
