Double jump on RD

[Malduik]

Hey Peeps

I fitted a used pair of X7 shifters to a training MTB bike yesterday. when i shift it keeps on skipping one gear, i.e. 1, 3, 5 etc.

 

I presume the shifter takes and releases too much cable with each shift.

 

Can i adjust the shifter?

 

(sorry to bug you guys, i've been waiting for 'Zin and the art of MTB Maintenance' for over a month from Kalahari. Apparently the WC is delaying all deliveries nationwide)

 

Cheers

What rear derailleur do you have on there?

[Malduik]

Shimano LX.

Does it matter? (the casette size is the same)

[Mudsimus]

The Sram shifters have a different shifting ratio than shimano. So you need a Sram rear der.

[Malduik]

All the rest LX, so i'll rather get shimmy shifters.

 

Cheers!

No. Just get a sram rear deraileur. That's all.

 

You can still use shimano casette, chain, front derailleur etc

Watch out for some X9 SRAM RD's - I have had two that stick! Must have been a batch fault ....

[stewie911]

How do you mean stick?

Like get stuck in biggest cog?

Sticky X9 RD: The movement up and down is not smooth and hesitates causing crunchy gears - even off the bike you can feel it. Some guy even posted up a utoob of the problem:

Caused me lots of grief. Tried everything to get gears right, eventually nailed it down to this problem, then saw others on the net picked it up as well. I 'upgraded' to X0, sent the one X9 I got from CRC back to them and got a voucher for the full value, other I got locally still with Solomons and 'the rep' but I can see a scrap coming on, there for even just a credit.

 

It's not a design problem: its a manufacturing / batch problem with clearances or something: they should do the right thing and do a recall.

O ok. Bought mine December last year and it's working perfectly. Got a medium cage though

Are you a Sram rep?

Or are you just trying to poison my mind with your crazy Sram talk???

Rode Shimano for 3 years - Changed to SRAM this year (X0 trigger / X9 RD combo) and haven't missed a gear since. Nothing like a picture to illustrate a point:

New bike will have SRAM X0 Gripshift / XO RD combo. B)

If you like the way Sram shifters work above Shimano. you can always just use the Rocket or Attack shifters. These are excellent prices for shifters.

The extra price of X0 is well worth it I reckon. As much as I would like to support local industry, even the cheapest here is just about 2x the CRC price, and about the price of an X9 (which could well be a lemon)

 

The X0 is very well made: and you can take it all apart to service it, the pins on the quadrilateral have circlips on them.
