Hi everyone! My wife and I used to tandem with an ill - fated GT Quatrafoil. Sadly we gave it to a collector friend and moved away. Never got encouragement from dealers over ordering 650B components -- at the time they were available in Australia but they didn't follow up and give me prices or timelines, so I stopped pushing the issue.
Last week we rejoined the community in that we were able to find a 1994 unused Trek T100 in the correct sizing in pristine condition. I am going over all of the systems carefully, especially to avoid corrosion, as we are 7 blocks from the Pacific Ocean. All of the components are identical to our GT's except I don't remember the stoker cranks as 175 mm. Might have been, not sure. The previous owner handed it over to us with new Specialized Flak Jacket tires, and they do look bombproof. I am excited, but the weather for once appears to be ready to return to its usual patterns, unfortunately. That's okay -- we need to replace the fresh water "lens" we lost during the long, hot draught. And the new tandem will help us witness the lens returning. We will have plenty of opportunity during the winter to "test" my maintenance and check the marsh nearby.
We had a shock seat post for the stoker, and I want one again. We are 10 years older! I wonder if anyone here has an idea how I might determine a correct seat post and shim combination for the tandem. I see the seat posts on the new Trek are indicated as 29.8. Either the choices are lesser now, or the tubeset used in the GT was more in line with available seat post sizes -- I think we used a 30.8 mm. post or something like that. This time, I will try a 27.2, but am unsure just what shim combo to use. Anyone have stories of what worked for you?
I have found the Trek to be stiffer than the GT, and about 2 pounds lighter, incidently. I had also forgotten about the wider turning radii! Dan
