I'd be grateful for any advice you may have to offer. I'm new to cycling, having bought a hybrid bike last summer, and I'm starting to struggle on rides of more than 30miles or so as I'm training for a 60mile local sportive
I'm probably just unfit but I wondered about the resistance I'm encountering with the tires that came on the bike. They're fairly knobbly (not as much as MTB) 7000*35C tires. The shop where I bought it suggested I could downsize to a 700*28 tire on the rims I have on the wheels.
I wondered how much effect would it have to go to a narrower, slicker and higher pressure tire? Enough to make it worthwhile or shall I save the pennies for a proper roadbike later this year?
If its worthwhile, any suggestions on suitable tires?
Thanks a lot
