RSX Front shifter
I have a Dawes Giro 300, the older type with conventional frame and frame
tubes. (circa 2000). It is equipped with Shimano RSX components, and the front shifter has become erratic, obviously the little pawl not catching which is well documented on this group and in other forums. I have done all the recommended fixes but no help so need to renew the component. Last time I took a bike to bits it had friction levers on the front tube, so this is a whole new ball game to me. I don't have a LBS so have to buy online, but the variety and choice is overwhelming. Just what do I look for as a search term. Shimano RSX seems to throw up everything but what I actually want, or am I being incredibly thick. The front is a triple, and the shifter is combined with the brake lever. I'm no luddite, but I can't help feeling the old style gears, friction, no indexing etc were far less trouble, or am I getting old. Thanks for any advice Bill |

I have the same issue which appears to be alleviated for a while by spraying liberally with WD40/GT85 whilst working the system. ...d |

That's about it. I even tried a high pressure air hose at work followed by WD40, made no difference at all. Gotta be a new'un, and it's gonna cost, I can feel it my water!! |

I have RSX shifters (STI) they have worked faultlessly for 7 years, I imagine when they go they go. They are now unobtainable, the current 7 speed alternative is Sora (vastly inferior) about £70 a pair. E bay often have left or right only shifters; could be your best bet. Have you tried Shimano for a replacement tumbler? (although taking it apart is likely to result in a search around the kitchen floor for small bits). But if it's shot might be worth a try. |

Shimano RSX seems to throw up everything but what I actually want, or am I being incredibly thick. The front is a triple, and the shifter is combined with the brake lever. I think you are suffering from obselete bits. At 5 years the bits on your bike are obselete as far as the parts makers are concerned. Yes, you will still be able to find stuff which works, but what was bought back then bears no resemblence to what is in the catelogues now. I'm no luddite, but I can't help feeling the old style gears, friction, no indexing etc were far less trouble, or am I getting old. If wanting a new combined brake/gear lever for the left brake lever & front gear changer, then you'll have to search around for someone with just that part for sale. Most retailers sell the levers in pairs, and you get the right had lever as well. Those levers are complex and expensive. Pretty much any Shimano lever will work for the left, so long as its for a triple mech. For the rear, you need the right number of sprockets (8,9,10). Price depends a bit on quality, a bit on weight, with a law of diminishing returns as the price rises. From £90 per pair, though I would pay a little more to avoid the most budget of models. There is the option of swapping to Campag shifters (significantly cheaper entry prices), but you need to do some research as to which Campag shifters will work with which Shimano mechanisms. Alternatives: Frame tube shifter for the front mech alone, leaving the rear mech controlled by the RH brake lever (and not be in bad company, L.Armstrong was using such on last year's Tour de France). You need to check that there is a threaded boss on the frame for this (it will be where the gear cable swaps from being in the flexible tube, to running down the frame; if you can unscrew/unbolt a fixing you probably have the correct fitting). Almost any shift lever will do for the front mech, though if changing the rear as well, you will need to match the number of sprockets. Shop price for good quality new is around £35 per pair. Bar-end shifters, which fit on the end of the drop bars. They are popular with touring bikes due to their robustness, yet not needing such a big reach as a frame shifter. For just the front, any model will do. If swapping the rear as well, then it needs to match the number of cogs on the back. Shop price for good quality items is around £40 per pair. - Nigel -- Nigel Cliffe, Webmaster at http://www.2mm.org.uk/ |

Just what do I look for as a search term. Shimano RSX seems to throw up everything but what I actually want, or am I being incredibly thick. The front is a triple, and the shifter is combined with the brake lever. First thing, check that the cable runs freely.You'll have to undo it from the front mech end, then push/pull it out a little from the gear changer.If it is a little stiff, then chuck it, and buy a new one for around £3(get the complete cable, not just the inner).If it is stiff, then that may be the cause of your problem. If the cable is moving freely, and you have sprayed plenty of WD into the shifter, then it is likely to be knackered, and a new one will be required. Unlike Campagnolo shifters, Shimano ones are not repairable, so you'll need a new one.Ebay, or look in the ads in Cycling Weekly for a new one. SJS Cycles have a Modolo left hand shifter for £25: http://www.sjscycles.com/store/vIndex.htm?item5621.htm It is different in appearance to your current one, but will work fine, ebay has a few on at the mo.

I have done all the recommended fixes but no help so need to renew the component. Thanks for advice/suggestions. I have just found on the US Ebay a brand new left hand RSX shifter/brake lever, exactly what I want. It cost a bit, but probably not as much as changing everything else to match new levers. http://cgi.ebay.com/ws/eBayISAPI.dll...tem=7213948971 Just in case anyone's remotely interested!! Bill |
