Theory Downtown Seatpost

This seatpost has a 27.2 mm diameter, which is a common size for many BMX frames. However, you should verify your frame's specific seat tube diameter before purchasing, as some models may require a different size.

The two-bolt design allows for much finer control over your saddle's tilt. By adjusting the tension between the two bolts, you can dial in the exact angle of your seat for better comfort and stability compared to the often limited adjustments of single-bolt systems.

This seatpost is designed for standard metal railed saddles. If you are using carbon rails, be aware that the clamping mechanism may exert uneven pressure, which could potentially damage delicate carbon components.

The 350 mm length is fixed, meaning you cannot extend the post beyond its physical length. You can, however, cut the post down if you need a shorter length for your specific setup, provided you leave enough material to safely secure it within your frame.

No, the aluminum construction is specifically chosen to balance durability with a lightweight profile. It is robust enough to handle the rigors of BMX riding without adding unnecessary bulk to your build.
