rapidfire shifters seized/stuck?
I went out for a ride today after not riding it for about 2 years and
I think the cycle gods have decided to punish me (I guess thats karma!!) I have a mountain bike with stx-rc rapidfire shifters (early 2000's I think, individual shifters without brake levers) with XT derailluers. My bike was stored in a dry shed so rust is not the problem but the thumb levers to shift up to a bigger chainwheel do not seem to be engaging properly. I had left the front derailluer on the midlle chainring and the rear in the middle of the cluster. I could shift between the granny and middle ring on the front but pressing the thumb lever down further/again to get on the big ring did not seem to engage inside the shifter and move the derailluer over. The same seemed to happen on the rear, I could only shift to a smaller cog than where it had been left and back up to it but I could not shift up to a bigger cog. I thought it may be due to cable stretch but tightening the cables made no real differencs. My guess is that the little pawls inside the shifters have got stuck and are not moving freely enough to enagage. Has anyone had a problem like this before after prolonged storage of a bike, I am thinking of trying to spray some lubricant inside the shifters first before resorting to anything more drastic.

Yeah, a bit of the ol' CRC/WD40 should sort it out. I had the same problem
with an el-cheapo Repco. -- www.ozcableguy.com www.oztechnologies.com "Darryn" wrote in message ...

There is a little pawl that can potentially come loose, but as suggested by OzCableGuy, a blast of WD-40 is the first step. You might prefer a silicon spray if you've got one, but just about everyone has WD-40 floating about somewhere. Otherwise STX-RC of that era aren't that hard to pull apart and fiddle with, within reason. IIRC it's a 4mm allen key to remove the dust cover, after which it should be fairly obvious what's out of wack. -- Dave Hughes | "Reading computer manuals without the hardware is as frustrating as reading sex manuals without the software." - Arthur C Clarke |

Cheers for both responses, luckily I have silicone spray somewhere in the back of the car for work purposes so I will give them a hit tomorrow. Hopefully it fixes it otherwise it looks like I am generation behind as far as components go, had quick look on ebay today and the majority of the shifters are all for 9 speed stuff :-( Cheers |
