Frequently Asked Questions (FAQs)
1. Do bike suspension seat posts work?
Yes, suspension seat posts work by increasing the flex of the seatpost, reducing the transfer of road vibrations and dampening impacts from bumps and potholes. This results in a smoother ride and less physical fatigue.
2. What is the disadvantage of suspension seatpost?
The main disadvantage of suspension seatposts is their increased weight compared to regular seatposts. The suspension mechanism adds around 300g of weight, which can make the bike heavier and potentially affect fatigue on long rides.
3. What size are suspension seatposts?
When choosing a suspension seatpost, it should have the same diameter as your current seatpost, typically 30.9mm. You can go smaller in size, but you will need a shim to ensure a secure fit.
4. What are the benefits of suspension seatpost?
The benefits of suspension seatposts include increased comfort, the ability to sit for longer periods, reduced lower back pain, improved capability for narrow-tire bikes, and performance that is not affected by weight or height.
5. What is the difference between carbon seatpost and suspension seatpost?
While carbon seatposts offer vertical flex on big bumps, suspension seatposts provide even more deflection and excellent damping abilities for both big and small bumps.
6. What are the disadvantages of a full suspension bike?
Full suspension bikes can be less durable due to more moving parts and the potential for damage if not set up correctly. They may not handle hard impacts as well as hardtail bikes.
7. Is it bad to bottom out bike suspension?
No, it is not bad for suspension to bottom out on the biggest, hardest hits. Suspension is designed to go through its full range of motion without detrimental effects or risk of damage.
8. How do I choose seat post size?
To determine the size of your seatpost, remove it from the bike frame and look for the stamped size just below the 'Minimum Insert' line. The size will be a three-digit number, such as 26.8, 27.2, or 31.6.
9. What is the most comfortable suspension setup?
An air suspension is considered one of the most comfortable and load-bearing suspensions, which is why it is used in top-of-the-line luxury and sports cars.
