Lapierre Spicy gearing issues

Hi all

First post, been riding a while but only just started tinkering with setup!

I have just bought a 2010 Lapierre Spicy 316 that has had its setup changed a little and I am having problems with it jumping/missing gears.

Here is the current setup:
SRAM X0 Shifters
PC991 Chain
SRAM X9 Mech
SRAM PG990 Cassette
Shimano SLX 3 speed with middle chainring removed

At the moment, when changing through the gears it jumps on the second and third smallest cassette chainrings and wont stay in gear. After a bit of messing around, I noticed that the shifters only appear to be 8 speed, however I though SRAM only did the X0 in 9 or 10 speed?

Would this account for the gear jumping?

My specialized road bike has a 8 speed cassette, so I swapped the wheel across (which was quite amusing) and it changed up and down the gears pretty smoothly. Could this be a shifter issue?

Sorry if this doesnt make much sense, tried to be as clear as possible!

Thanks...Andy

    How are you coming to the conclusion that the shifter is 8 speed?

    Which x9 rear mech?

    Running a 3 ring crankset with the middle ring missing will also cause issues.

    Hi, thanks for the reply.

    I am coming to that conclusion because there are only 7 clicks when changing gears (gear im on then 7 up or down).

    Rear mech just says SRAM X9 on it and 1:1 Actuation Ratio. How do I tell what variant it is?

    I am looking to add the extra ring to the crankset, it had already been removed.

    Thanks

    I would say the gears are totaly set up incorrectly.

    SRAM came straight out with 9 spd on their triggers.

    Slacken it all off and start again.

    I have just had a check of the cassette and found that the 3rd chainring is the wrong size for the cassette. It should be a 14T and is a 13T. Would this be enough to cause the problem?

    The 7th cog (1 biggest size 9 smallest) could be 14T or 15T

    There are a number of versions.

    Sounds like there are a few issues. Someone has just thrown on their old spares to sell the bike and kept all the good bits.

    Which is exactly what I'd do. And what the missus gets, but she has the torque of a mouse so stuff works better for her. Second-hand is a mine field if you don't know your stuff.

    Missing middle ring and incompatible components are not a good sign.

    do you need the triple front chain rings as you could swap it for a single narrow/wide single ring and chain device maybe?

    I'd be tempted to re do the gear indexing as a start and then take it from there.

    There's no need for a chain device with a narrow wide ring.

    It's a cool thing to say though
