Shimano Revoshift repair My bike has a grip shift (Shimano revoshift) which isn't shifting through all 8 gears.  Even with the gear cable removed (it recently broke) it will only shift through half of the gear numbers and some blanks.  It is almost as if the number dial has slipped around the shifter.

It still sort of works ok but I can't use all of the gears.

Is it just a broken shifter that needs replacing or is it something that can be fixed?

Thanks in advance for any advice.

It depends on how much you value your time. Taking one of these to pieces and putting it back together again is do-able but may not give you the fix needed, whereas, buy the new part and it might save you time.

To give it a go, type in 'revoshift' into http://techdocs.shimano.com/techdocs/index.jsp and pull up your manual.

And personally, if I were you, I would give it a go.
