Stoker feels too cramped, so looking for a new tandem.. any help?

Hey tandem folks

After trying different stems, seat posts and handlebars, my stoker just doesn't like the cramped position of our Dyno Crestline tandem. She can't lean forward enough to take the weight off her rear, so after about 5 miles, even with a suspension seat post, she's not a happy camper. So we're selling the Crestline, and I've been looking on Craigslist for a replacement. Right now there are two I see that are in our price range, but I'm not confident that we'd be happy with either one

The first is a 1992 Gary Fisher Gemini.. looks nice the rear seat post measures 17" which doesn't sound promising since we want more space for the stoker.

The second is a mid 90s Trek T-200.. it looks to be nicely equipped but it's a 700c bike with drop bars.. I don't own any other 700c bikes so I'd prefer to stick with 26", but maybe this one might be designed for the stoker to be more stretched out?

Does anyone have any experience with either of these tandems or have any other advice about how to improve stoker comfort? I tried a laid back seat post and a suspension seat post but neither one really helped.

We used to own a Gemini tandem. The handlebars were the bullhorn type and came up alongside my hips; if I shifted from side-to-side, my hips touched my stoker's hands. I don't think it would have the room you're looking for.

Thanks, I found an old ad for the Gemini and they touted the wide bullhorn bar as a feature that allowed the stoker to get more forward. I was thinking that it might cause issues like the one you described.

think you are looking at the wrong data , its the rear top tube length you need to be comparing.

Are you able to ride either or both of the bikes? That would be the only way to be sure.

The recent Cannondale road tandems have a long stoker cockpit--too long for many.

The Trek T50, T100 and T200 have the same frame. In period test reports, they were noted for having long stoker cockpits.

We have a T50, and love it. Here are three listed on SF Bay Area CL:
trek t 100 double cross two person bike
two person bike
TREK T-200 TENDEM BIKE

The IBIS tandems of the late 1980s/early 1990s have a very long stoker cockpit; longer than out Trek, and have ISO559 (26") wheels.

Frantik -

Can you measure the rear top tube (from center to center) of the bike under complaint and post it.

With that all of us can put the ruler to the 2bikes around us and post those which have a longer cockpit.

yes but a shorter seat tube is likely to mean a shorter top tube

the distance from seat post to seat post is approximately 25"

indeed, but often it is hard to measure a bike over the internet

also the stem isn't pointed toward you on a single. i would only use the measurement to compare with other tandems

'95 Ibis Forte = 27 inches (center to center) between the seat posts

2012 Rodriguez Trillium that was built custom for us is 28.5 inches on the same dimension

You didn't mention what type of different bars you tried, what about "bull horn" shapes? They tend to be significantly wider than drop bars, and I find I (as the stoker) can position them farther forward as compared to drop bars because they clear the captain's hips/legs better.
