Hello all...My first post...I have a late 70's early 80's one speed 26" bike that I am converting to a 3 speed...the number of teeth on the pedal sprocket is 44 and the rear is 19 teeth...with the 3 speed hub installed it will have 44 teeth in front and 18 teeth in the rear...will this work or do I need to add more teeth to the rear...There is a slight hill to go up to get to town...any suggestion would be helpful...thanks, 1.75
