Tarmac SL2 with Zipp 303's - 13.7
Tarmac SL2 with Williams 30 Clinchers - 15.3
Cervelo P3 TT bike - 17.8

I only have 1 Tarmac, I just wanted to show the difference between weight with race wheels and the wheels I use in training. I'm hoping to do a few upgrades next season and get the bike down to 13.2
