Torpedo 3 speed hub indexing help please
Dear All,
My wife's Brompton has a Torpedo (Spectro Sachs/Sram) 3 speed hub which no longer seems to index. Am I correct in assuming the indexing occurs with the shifter? If so has the shifter worn out? Or have I got to do something with the hub itself?? I had a quick look to see if I could find any answers online without success. Any ideas? Thanks for your help! Nick |

Thanks Ian.
Yes it doesn't appear to index at all, I'm assuming the lever has had it then? I might see if I can take the lever apart and repair if possible. I just wanted to be sure I wasn't missing something simple and you've helped a lot, thanks! Best wishes, Nick |

You might be lucky - something might have jumped out of place or got stuck rather than broken or worn away, but it's unlikely you'll get parts for it if anything needs replacing. regards, Ian SMith -- |\ /| no .sig |o o| |/ \| |

Nick I think that a broken, very slack, or jammed cable (with enough slack on the lever side of the jam) may also produce that "free at the lever" feeling. When you pull the lever (even if it won't stay where you pull it to), can you see the cable move back at the hub? There were a couple of different levers over the years to go with that hub, but the one that I am familiar with relied on tension from the cable to keep the lever in the index slots. This doesn't address the lever directly, but may be of some help in chasing down the problem or getting it back into adjustment: http://www.sram.com/_media/pdf/sram/...GHS_MY05_E.pdf hth, bookieb. |

Many thanks for all replies.
I fixed it! I took the shifter apart to discover the torsion spring had popped of the ratchet catch so it wasn't ratcheting any more. I popped it back on and it was fixed within 5 minutes. If only all repairs were so simple!! Best wishes, Nick |
