I recently discovered there is a carbon seat post available for the SC which begs the question why wasn't it included as standard. Left me wondering what other corners have been cut adding further weight to the bike. Just doesn't reflect well.

Those saying weight doesn't matter aero is more important. Not sure what aero has to do with the weight, the two are not mutually exclusive. You can be light and aero at the same time.

Additionally when you are going at your absolute limit on a tight undualting, multi lap course I can 100% guarantee weight will make a difference. Yeah the bike goes fast when up to speed but getting up to speed takes a little longer, especially with multiple 180 degree turnarounds.

The wheels, saddle, and crankset have all been changed on mine. Still weighs a ton. I even swapped out the stock stem which was also heavy.
