My bike is a 2 year old, less than average mileage, 18 speed tension grip (not Shimano) shift type, dual spring and was never a problem. In a moment of madness I decided to make it an index shift and was informed that by changing the right hand grip it would become an index shift.
The grip shift is a Shimano index type but the other parts are not. Now I can only fine tune it so far. 1 - 6 will give me all 6 gears. When I go from 6 to 1, I only get 6, 4, 2 and 1.
I have tried everything; adjusting stops; re-tensioning cable; another grip shift; grease cables; fine adjust thumb screw; take it to Halfords; take apart 6 speed cassette and change ball bearings.
I have also noticed a play on the cassette when free wheeling but the experts tell me that it is normal. I have not noticed it on other bikes.
Any suggestions would be welcome. My options are to go back to tension shift or change component by component until (if ever) I get it right, starting with the cassette and chain and finally the rear derailleur
