What does seatpost offset do?
However, whilst you can always cut a seatpost that’s too long, you can’t add to the length if it’s too short. Seatposts can be zero offset, or come with layback. A zero offset seatpost will place the saddle directly above the clamp – though of course you can adjust it forward and back on the rails.
How do I know what size seatpost to get?
To find out the diameter of your seatpost, you must remove the seatpost from the bicycle frame and look for the size, which is stamped just below the “Minimum Insert” line toward the bottom. The number will be a three-digit number (such as 26.8 or 27.2 or 31.6).
What does a zero offset seat post do?
Apart from shortening reach, the other thing a zero offset seat post does is to place your knee more in line with the crank. For those with a bad knee it can help. A zero offset seat post is a much better option than moving your saddle too far forward and losing the flexibility of the rails to dampen bumps.
What is offset offset?
Offset is the distance between the centerline of the seatpost tube, and the centerline of the clamp area. Shims are often available to adapt a too-small seatpost to a too-large seat tube.
What is the best offset post for a mountain bike?
Zero offset posts are really best suited to MTBs that have slack STAs. Fewer people all the time take any stock in the idea that femur length and the resulting knee over pedal measurements are relevant to producing the proper rider position. It’s better to have the rider properly balanced over the saddle and ignore KOP
What determines the size of a bicycle seatpost?
The size of the seatpost is dependent upon the internal dimensions of the seat tube of the bicycle frame. They come in various diameters, lengths and offsets. Offset is the distance between the centerline of the seatpost tube, and the centerline of the clamp area. Shims are often available to adapt a too-small seatpost to a too-large seat tube.
