Unless really really hilly I prefer to use the bent: Rotator Ti Pursuit. It is far more
comfortable and not enough slower to make me want to switch. I do ride a DF
bike on certain group rides. The Cheaha Challenge has cerca 10kft of climbing,
but I skipped about 2500 of this by omitting the central 12miles of the 102 and
doing only 89mi. That is the R side pix. The other pix is from the Leaves of
Lincoln century in south central Tn, very scenic century.
