Hey there!
Question regarding which tyre is faster/more efficient.
I have a Zipp Firecrest 404 25mm @95psi (Clincher). I also have a Zipp Super-9 21mm @100psi (Tubular). Both 11 spd.
I rode the disc for the first time today, as I normally ride the 404, and felt as if I struggled to maintain speed/momentum.
Thoughts?
