spent a year trying to find one with cannondale corporate help- gave up and just found one in canada recently- i bought the 50-50 nexus cannondale 2 years ago and love it - own about 10-11 cannondales now- all high tech stuff unlike these- but these are turning out to be favorites-there is someone from new york selling a new 50-50 still- scarce as hens teeth
good luck- my search was worth it
