How much speed difference between Big Apples and 23mm/35mm tyres?
So I'm thinking about building a bike with Big Apple tyres, I currently run 23mm tyres on my road bike and fixed gear and 35mm on my hybrid.
I was wondering how much of a speed hit I would take with the Big Apples.
My thoughts are that it will be minimal as I should be able to go over rough surfaces without slowing at all.
Want some opinions of hands on experience though!
So how fast do you ride? Fatter tires have more frontal area and consequently more aero drag. The faster you ride, the more important aero drag becomes vs. other factors.
For a guy like me there might not be any speed difference.
I mainly ride two bikes right now. Road bike with 700c26 and Trekking bike with 26"X1.75 tires. My impression is cruising speed is similar. The heavier fat tires take more effort to accelerate - away from stops and up hills. At the speeds I ride, aerodynamics of the tires don't count for much. And yes, I don't have to slow down for gravel or dirt or bumps as much on the fat tires. I run the skinny tires at 100 to 110 PSI and the fat tires at 45-55 PSI. Fat tires are definitely a cushier ride. Ride times over the road (same loop) are a bit longer for the fat tires
My average speed varies between 13-16mph over 9.5miles. Top speed around 25-28mph. The bike is going to be a fixed gear too.
I just checked my bike log. Same 16 mile loop. Average speeds: 13.4 MPH on the road bike. 12.7 MPH on the fat tire bike. Loop is all paved road in fairly good condition. Less than a 5 minute difference for 1 1/4 hour ride time.
Sounds excellent, thanks. I'd probably see a speed increase or the same speed due to the roads I have to travel on - they are really poor quality!
The Liteskin version might gain you a few tenths of an MPH. It would have a thinner, finer sidewall. I have not tried them myself, I was merely considering them.
I find that Big Apples are efficient at slower cruising speeds and esp over rougher roads and cobbles. At higher speeds, narrow road tyres win out.
The longest ride Ive done on BA's is about 30miles. They are a nice city tyre but I don't rate them as rapid mile-munchers
