I am new to this forum, this post was interesting, now for a little history. My wife and I have ridden a road tandem for quite a long time together now. We have had four tandems a KHS, Cannondale, Trek and the Co-Motion supremo we ride now. We are in the process of having our fifth tandem frame set built, it will be a new custom Co-Motion Robusta.

The Bontranger tandem specific race lite wheel is designed for tandem use and it is not for single bike use like the regular race lite wheelset. The Tandem specific race lite likes a 25mm to 28mm wide tire due to it being around 19mm wide from braking surface on one side to braking surface on the opposite side. The 28mm wide tire will actually have less roling resistance at 120 PSI and corner better, support more weight, ware better and give a much better ride. A person has to pump up a 25mm tire to around 145 PSI to get about the same rolling resistance as a 28mm at 120 PSI on a tandem with a harsher ride. A normal 25mm tire in my opinion can be a little narrow on a road tandem application in my opinion. The Continental Ultra Gater skin is a great tandem tire and we have had no tire failers in three years now with them, they are bar none the best tandem tire on the market.

I think the choice of a 28mm gater skin was a great choice.

Good luck,
