Un True .. try 'it's not much different than' .. an 8 speed..

Evolution was> 5 standard (120mm), +1=6, 7 was made to fit in 6 speed (126mm), and then 8th was added to 7.


Frame would Be a 120 rear .. the new stuff is requiring a 130 Dropout spread ..


I reccomend buying a New Bike . to get all the bells and whistles you Now want.



turn the old one into a 1 speed .. with a 1 speed freewheel .. on the Hub .[ or fit an Internal gear Hub in a new wheel] ..

there can be a de dishing to move the hub over to be in the center of the dropout.. then screw on a single speedfreewhel
