I find myself standing on the edge of the great swirling weight weenie vortex and feel it pulling me in...
We bought our tandem about a year ago amid a lot of pondering. Wanted something we could ride for exercise and get to doing some century rides. Figured someday we would enjoy doing a bit of bike touring. Maybe travel with the bike. And it is our first tandem. So we had to balance the bling factor and money with what we really needed or was prudent to spend. As much fun as a $10k tandem might be it felt/feels just a bit extravagant. So we chose a Co-Motion Primera Co-Pilot. Figured we could ride and enjoy and if things worked out maybe add a few upgrades in the future.
We have enjoyed the bike and it works pretty well for us. We did add a Thudbuster ST to the back end. Biggest downside is at 43 lbs it is not a lightweight.
So the other day one of my dream upgrades dropped into my lap. I picked up a very lightly used Gates carbon belt drive for half the new price. But I will need new cranksets to go with it. I could of course pickup up a set of FSA Gossamer cranks for $430 or the much sexier FSA SLK carbon cranks for $1080 which are about 175g (6 ounces) lighter. That seems like a pretty big step in $$$ versus the benefit but they would look really cool on the bike
So on a bang for the buck basis what upgrades and and in what order would you do here with a motivation towards reducing weight/increasing performance?
