We pulled the trigger on a set of Topolino wheels last week, they arrived on Monday and i mounted the tires and installed them on the bike that evening.
The total weight of the new wheels with rim tape installed (that is the way I received them) is 698 grams front and 900 grams rear. Total weight with tires, tubes, cassette, computer magnets and quick release skewers is 2567 grams. The Bontragers weighed 3333 grams similarly equipped. I bought the wheels from Mel at Tandems East. They are the new True Black ATR 3.0 tandem wheels.
The bike now weighs 28.08 pounds with two computers and a heart rate monitor installed.
We took it for a 33 mile ride this morning and at about the 4 mile mark I asked my stoker (wife, Chris) if she noticed any difference in the bike. She said that she was getting ready to say something, she said that if felt lighter. We both agreed that the bike feels, lighter, livelier, SMOOTHER, more comfortable and more responsive. It was very comfortable to begin with. (the bike is a 2010 Calfee Tetra).
It climbs even better, there is a steep little hill just after a river bridge that we went up faster than we have ever gone.
So bottom line we like the wheels a whole lot!
