Tandem Sizing(6 posts)

My wife and I are considering a tandem. She may not agree with that statement but I do.

Regardless I'm curious about sizing a tandem. All I see is S, M, L, XL sizing. Is the rest done with seat post and stem?

My wife and I are radically different sizes. I ride a 63cm; she rides a 47cm. Is this even possible?

Absolutely it is possible. Most likely you will have to go custom, though. My wife and I are not quite as dissimilar in size as you; I ride a 64cm and she rides a 51cm. But before you buy, be sure that you are able to develop the compatibility of riding styles that is necessary for tandemming. Some couples just shouldn't tandem!

Recognize that the stoker size can be pretty flexible, as you typically have an adjustable stem in the rear, and top tube clearance is not needed in the rear. You should be buying a tandem from a knowledgeable shop (one that sells a number of tandems a year, not one that "can get one for you"). The shop will guide you.

Finding a shop can be harder than it sounds. The only shop I know of around Seattle that sells tandems is heavily geared towards women. I've never felt well treated there. I guess I'll be looking around.

There is a lot more flexibility with tandem sizing, especially the stoker compartment, with the use of various size stems and seatposts. You may not need a custom-built rig, but you do want to find an LBS that knows what it's doing. Cannondales have low top-tubes and small diamonds made with oversize tubes. As a result disparate size riders are fairly easy to fit on their stock bikes. It sounds like you need an XL/S, but you may be okay on L/S. The captain's compartment is what you should focus on to ensure that you are not too cramped. Santanas are nearly all custom builds so if you have the money, you may want to go that route. Lot's of luck.

I have a tandem with my 11 year old daughter. I ride a 66 cm and she's, well, 11 years old and rides a 24" bike. We have an XL Burley Rumba. We had to put one of those $10 head tube extensions on the front for me, but my daughter has no problem on the back. It handles very well and is very stable.
