Hello all,
This is my first post, and I have a question regarding my tire/tube setup and how it impacts my bike.
My bike's stock tires were Vittoria Zaffiro (700x23) which I rode at 120 psi with Forte standard tubes. The Zaffiro tires weight 340g and the Forte tubes weigh 90g.
I ride in the southwest, and due to constant thorn flats (I'm sure you've heard of our goatheads), I recently upgraded to a set of Continental Gatorskin (foldable) 700x23 tires and True Goo tubes. The gatorskins weigh 230g and the goo tubes weight 180g (verified). However, these tires I've been running at 110 psi, per Continentals recommendations (although the Max is 120 psi).
Since I made this change my bike is noticeably "slower." Slower to accelerate, slower/harder going uphill, and my perception is that it takes longer on flat surfaces to reach top speed.
But, the tire & tube weight is similar for both setups? Vittoria (340g) and Forte tubes (90g) total 430g; the Continentals (230g) and Goo tubes (180g) total 410g.
So, is my bike dogging because of the lower pressure? Or am I missing something else?
Thanks for the assistance! No other changes have been made to the bike during this time-frame.
