Hi from Montreal,
We are still riding our single bikes on trainer as winter here is far from being over. We should pull out the tandem probably around mid-april. We bought the tandem late last summer so we only rode it 6-7 times. We still have things to learn but I can say that both my wife and I are really pleased with the tandem. Hopefully this year we will have more time for tandem rides.
I got few questions regarding tires size for tandem. But first some data. I am weighting 165 lbs, my wife 125 lbs, the bike 38 lbs and with water bottles, some tools and a lunch, the total weight is propably close to 340 lbs. Right now the tandem is rolling on specialized armadillo 700 x 28 tire inflated at 125 psi. With those tire, the flat spot look to be around 5/8-3/4 of an inch. Because of that, I am a bit affraid of snake bite. I don't have much experience with tandem so I don't know if this size/kind of tire is appropriate for us. Is it worthed to go with a larger tire. How speed is going to be affected with a larger one. May be another type of 28 will be better? I am a bit confuse, tires are not cheap and last thing I want is to have a collection of tandem tires in my garage.
One more thing I have observed is our speed. I was in the impression that tandem were much faster than single road bike. Well it is faster but not what I expected. May be because my wife and I are not yet fully synchrone. I don't know, but downhill speed are just a bit faster than a single. Could it be the rolling resistance of the armadillo??? If you have some comments on all this it will be well appreciated.
Thank you to all for your help. Have a nice day.
