what is this shifter model
quick query - my son's bike's rear derailleaur shifter is broken
(won't shift at all) leaving said bike in the lowest cog. Here's a (poor!) picture of the shifter http://www.facebook.com/photo.php?p...01&id=620385517 can anyone identify what "model" of shifter it is so i can get a replacement (?) to fix it. Alternatively, is there something "obvious" that I can do to mend it (I am very new to all of this!). cheers ian |

Are you sure it is the shifter - disconnect cable at other end? Could be the cable, or the spring in the derailleur itself. In your shoes I would go to my local bike shop - it won't cost a lot. |

Or a cheap bike. Older designs seem to kick around on cheap models for decades after they have vanished from posher models. Any 5-speed shifter will fit (assuming as Geoff questions it is the shifter and not cable or bent at derailleur at back wheel), a local bike shop which does repairs should be able to help. Worst case, a friction based shifter will work. > Are you > sure it is the shifter - disconnect cable at other end? Could be the > cable, or the spring in the derailleur itself.

No idea, sorry. > > Alternatively, is there something "obvious" that I can do to mend it > Unhook the cable casings where they're attached to the frame stops and make sure they slide freely over the inner cable (pushing the rear mech in/out depending on type will give you some slack, you may also need to screw in the adjusters on the mech and lever). If they don't then pull on the inner cable where it leaves the lever and try operating the lever. Often the cable will be seized but the shifter is OK, so just replace the cable (inner and outers). |
