We rode from Bluemont Park in Northern Virginia down parallel to I66 on the Custis Trail, for me a
challenging ride of many short hills and down slopes requiring lots of shifting. All the way to
Rosslyn, then a Quizno's, and the bus back.
The wide range (24 / 35 / 51) x (34 / 24 / 20 / 18 / 16 / 13 / 11) gearing worked pretty well. On
the varying terrain I was able to keep "hooked up" as pitch and speed changed continuously. This is
I think 657% range. The front is a mite touchy with that big jump. Harris recommended an R443 FD and
it seems just right. A few tuning issues...
The cassette version is 34 / 28 / 23 / 19 / 16 / 13 / 11 and may soon be installed on a Lightning
Thunderbolt if I can resolve a few issues.
This gearing may not be for you. I think it is better for riders with limited power, as have I. If
you can push and spin, you might not like those wide (though regular) jumps.
