    Hi all!

    I’ve been into bikes since I was a nipper but never bothered to try to understand them. I’d usually sell a bike if the the gears started slipping!

    September 2007 saw me buy a new Specialized Rockhopper disc 2008. It’s a great bike and has got my enthusiam for riding back. After taking her up some hills over the last few months the components have worn considerably, culminating in the back brake pads wearing down to the metal and the chain slipping like mad. After getting a book and reading online, I worked out how to tune up the gears. I bought a new 9-speed shimano chain. I went through the motions, carefully lining up the gears on the adjusters, but couldn’t get the cable tension right in the middle gears for them to line up properly. As I slowly clicked the indexed selector I realised that I only had 7 clicks, whereas the cassette is a 9-speed? WTF? Is this right? From a engineering point-of-view this clearly is not right.

    The shifter claims to be (it’s written on the shifter) an LX-M530, which is a 9-speed shifter, but mine only has 7 clicks and doesn’t correspond to the 9-speed shimano cassette I have on my back wheel? The LX derailleur is also a 9-speed.

    This is confusing me. Am I missing something here? Has anyone else experience of this?

    I thought I’d compare my wifes bike (a Giant XTC4.5) as this shares many components, inc gears with mine, and hers is the same!

    Any help would be appreciated with my quandary, sorry the post is so long winded!

    well you’ve got to remember when you do the first click your allready in a gear 😉

    If it was bought as a new 2008 model, it shouldn’t have a 7-speed shifter, as these went out ages ago.

    I’ll stick my neck out and say that you have a faulty 9-speed shifter.

    Thanks for the posts.

    I thought about the gear I was already in after I posted it! But that means it’s an 8 shifter?

    If the shifter is faulty how come my wifes identical shifter makes the same amount of clicks?

    Shall I just buy a new shifter? That’s what I’ll probably do, I usually just throw money at problems! 😕

    Take it to a decent bike shop and get them to analyse the problem. They should help if they sense a sale of a 9-speed shifter out of it. 😛

    Let’s just back track a bit, as I’m

    The bike certainly is 9 speed, and as you say you bought it new, then it surely must have been operating at some point as a 9 speed.


    “SHIFT LEVERS Shimano Deore SL-M530 trigger

    CASSETTE Shimano HG-50, 9-speed, 11-34t “

    You say that the only “drivetrain” component that you have changed is the chain, therefore the bike is still NINE SPEED.

    It’s a while since I’ve experienced problems with shifters that are similiar to this, but I think the problem is with the tension of your gear cable.

    Did you change the gear cable at all?

    Is it seated correctly in the h/bar mounted shifter mechanism, is it correctly tensioned in the rear shifting mechanism near the cassette.

    I want to learn about the components so that I can fix it if it breaks rather than take it to a shop. I’ve learnt a lot in the last few months and I’m keen to continue the curve, however steep it may be!


    Yes, I looked at the original specs and saw that the components are 9-speed everything, that’s why I was confused when I only heard 7 clicks.

    Now, I’ve been trying to tension the gear cable but the cable is quite short so I’ve been having trouble getting a decent tension. I let out the tension alltogether, then pedled the crank so that the gear fell into the highest cog, then I clicked the indexer and it went through 9-clicks, so that’s that mystery cleared! I think my cable is too short so that’s the next thing that’s gonna get replaced.

    Thanks again all, I’ll let you know when I break it next! 🙂

    make sure the screws (the stops) on the rear mech arent wound in too far. if they are, you will probably only get 7 clicks out of it as it wont let the shifter go any further.

    Is the cable outer seated correctly in it’s stops ? I was mucking about with my brakes yesterday, put new pads in the back, couldn’t work out why the cable seemed to be so short. 😳
