Let's take a look at 700c vs 26 inch wheels for bicycle touring. I've ridden both for thousands of miles all over the world on bicycle tours, and here's my opinion on what's best.
700c vs 26 Inch Wheels for Bicycle Touring
The subject of which is the best wheel size for bicycle touring can lead to heated discussions that often ramble on for several days in forums and Facebook groups. The 700c vs 26 inch wheel debate can sometimes be as passionate as the cycling helmet one! Over the course of several long distance cycling trips around the world, I have come to my own conclusions which is the best size. Based on 40,000 kms bicycle touring, I've concluded that 26 inch wheels are the best for bike touring. Here's why…
Difference Between 700c And 26 Inch Wheels
What really is the difference between 700c vs 26 inch wheels. Really? Obviously, one is slightly bigger than the other one, that goes without saying. But what else is there? The answer to this from a technical point of view, is that 26 inch wheels are stronger. As touring bicycles carry quite a bit of weight in terms of luggage and of course the cyclist themselves, this is important. Considerable strain on the wheels, especially when cycling over rough roads, will lead to broken spokes with weaker 700c wheels. Trust me, I've been there and done that!
But don't 700c Wheel bikes go faster?
I'm going to say yes on this one, I think they do. I don't have exact figures which are scientifically proven, but I would say you could average a km or 2 an hour faster on a 700c touring bike when compared to a 26 inch one. This is only on sealed roads though. I believe that a 700c wheel bike wouldn't give the same advantage over rougher terrain on a fully loaded touring bike.
But what about wide tyres?
Being able to fit fatter tyres on 26 inchers is also a trait that makes them the best wheel size for bicycle touring. Whilst skinny tyres are required for high speed road racing, they are less than desirable for bicycle touring, especially on rough roads. Fatter tyres will give better grip, and this is most noticeable on sandy sections. Again, when I cycled through the deserts of Sudan, although I managed it on 700c wheels, life would have been a lot easier with 26'ers.
700c vs 26″ Wheels Decider
The real decider in the debate between 700c vs 26 inch wheels for me however, is the availability of tyres and inner tubes. 26 inch wheels are simply the most common wheel size found throughout the world when compared to 700c. This means that buying tyres, inner tubes and even new rims should they be needed is much easier, especially in less developed countries. I learned the hard way when cycling England to Africa on 700c wheels, that I would have been far better off on 26 inch wheels. I couldn't find any new inner tubes or tyres for over 2000 miles, and ended up getting new tyres and inner tubes flown out to me at a great expense. Seriously!
700c vs 26 Inch wheels conclusion
So, short, sweet, and to the point. In my opinion, the best wheel size for bicycle touring is 26 inch, and indeed this is the wheel size I have chosen for my current expedition bicycle. I'm certainly not saying that I will never throw a spoke again, or will be able to find spare tyres in every country I cycle through, but overall, having 26 inch wheels for bicycle touring makes far more sense than having 700c wheels.
