I SO wish that Cannondale would have gone with a traditional round seat post instead of the goofy teardrop-shaped one, because it really makes it difficult and limited to replace that thing!!! Grrrrrrrr. I absolutely despise my stock seat post/clamping system on my Synapse and would love to replace with something that is easier to adjust...but not many reasonably-priced choices out there when you're limited to a teardrop-shaped opening in the frame.
