The good doctor

I had to curtail my rise this morning as the rear shifter has stopped working and the cable has gone slack if this helps identift the problem, To start with the lever would not allow me to change up but I could drop down the last couple of gears and then up to the sticking point however it sstopped working completely.
Any thoughts I need this sorting asap.
Thanks
John

Cables sticking in the outers?
Are the outers sitting in their stops properly all the way from the shifters to the mech?
If you unhitch the cable from the rear mech can the mech move freely?0 -
does the cable tighten up when you up-shift?
if not your shifter is bust.
to check the derailleur lift the bike so you can spin the cranks, with all tension off the cable the chain should be on the smallest cog. Now pull the cable and the derailleur should move in toward the bigger cog. If this happens the derailleur may just need adjustment.
Google 'park tools' for a great site for workshop/setup etc instructions.0 -

Hopefully you can retrieve the end of the cable that you've left behind in the shifter. have a look on YouTube for a video of somebody doing the job; also have a read through the instructions on Shimano TechDocs.0
