@pushkar, Since Kinekt comes in 350mm or 420mm length, I'm wondering which you are including in your bikes since they are the same price. If it's 350mm is there a reason why? I would think that 420mm would give people more options, but I'm not sure. Thanks in advance.
Depends on the frame size and comfort. Here is abroad guidline
You need the larger seat post in the following scenarios
1. If you ride size small frame and have in-seam over 31 inches
2. If you ride size medium frame and have , inseam over 33 inches
3. If you ride size large frame and have , inseam over 35 inches
4. If you ride size XL frame and have , inseam over 37 inches
