I am a 260 pound stoker. (spinning three times a week to try and lose the weight) My wife and I are about to order our first tandem, (Joint Venture). I am confident that the front wheel is strong enough to handle our weight. I have concerns over the rear wheel. (700c wheel) Looking at wheel prices it looks like a new rear wheel would add another $500 to the bike cost. My questions are these: Are there any 400+ tandem teams out there. What type of wheel do you use. Our initial rides will be mostly on flat, some what smooth asphalt. Do you think the wheels can handle this until I can upgrade the rear wheel? What type of wheel would you recomend.
