[Unclejack]

just been rumaging through my cassettes and found this. i have everyrhing in there from six speed deore to ten speed campag so can anyone help identify the top one/ the six that are shown. i know its nothing flash but its a lot lighter than the usual standard stuff as shown by the comparitivr 28t below. 7 speed xt or something? theres no markings on it at all. thanks y'all.






i'm disapointed noones waded in with a "is it bananarama?" etc yet...
