Will n 9 speed front shifter work with a 10 speed front dérailleur. Specifically a 9 speed gripshift?

9 speed shifter can be used with a 10 speed derailleur - no problem.

Just adust the limit screws on derailleur accordingly.

 

However what do you mean by "will 9 speed shifter work with a 10 speed shifter"???????

Hmmm, you can only use one at a time - hahhahahaha!!

Cool! I see you fixed the typo error - LOL

 

In connection with gripshift question- yes - should work fine, however try and keep same make of groupset parts,ie. use Shimano with Shimano, Sram with Sram. The shifting ratio with Sram and Shimano is sightly diffent, so could cause jumping of chain in certain gears.

Thanks for the advice. Post fixed.

 

I want to stay with gripshifts. I run a X0 shifter with XTR derailleur.

 

On my new bike I want to go 3x 10 but with gripshifts. I have heard the new SRAM 10 speed gripshifts will only be 2x10. This way I can keep my X0 3x front with a XTR 10 speed dérailleur front

The XO shifter with XTR RD may cause a small problem. If you can live with a chain skipping a gear normally near top gear limit, and sometimes low gear limit then go for it.

I cant remember the correct ratio for the groupsets but for sake of explaining the problem Shimano works with 1:1 ratio and SRAM works with 1:2 ratio. So in some gears it will work perfectly but eventually the ratio catches up and the chain will jump a gear.

 

Hope this helps.

Front Derailleur, I think, shouldnt be a major problem,I think it should work (not 100% sure) its the rear derailleur thats gonna give the problems

I will go SRAM shifter and derailleur on the back. On the nine speed the SRAM XTR combination works very well on the front. I know the back is not compatible.

<p>I have the same question for a road bike. As far as I know, a 9-speed shifter would have 9 &quot;shifts&quot;, therefore you can use it for a 10-speed cassette, but then you will only be able to use 9 gears? 10-speed shifter would work for both 9-speed and 10-speed cassette?

 

Also what about the rear derailer - it that linked to the shifter? And chain between 9 and 10-speed is also fine, I assume?

The derailleur will do what the shifter tells it to do, so as long as there is enough space between the limit screws you should be able to get just about any derailleur to work with any shifter. This will apply to both front and rear. The shifters need to be compatible with the cassette. Don't mix 9 and 10 speed and also check which brands are compatible. The derailleurs obviously have to be able to cope with the chainring and cassette range. Chains can be used backwards ie 10 speed with 9 and 9 with 8 etc but rather use the correct width ones.

The derailleur will do what the shifter tells it to do

I don't think it's quite as simple as that.

 

To get perfectly indexed shifting, every click of the shifter needs to move the RD by the cassette spacing amount e.g. one click moves it 4.55mm for Campag 9 speed vs. 4.12mm for 10sp.

The movement per click is determined by the shifter pull ratio (the amount of cable the shifter pulls in or releases per click) and the derailleur throw ratio (the amount the RD moves for every mm of cable movement).

 

There are three scenarios for mixing components:

1.) Shifters have the same pull ratio, different derailleur throws. As an example, both the 9sp and 10sp shifter could move 1mm of cable per click. The 9sp RD then moves 4.55mm per 1mm while the 10sp moves 4.12mm per 1mm. In this case, you would need to match the RD speed to the cassette speed. 9sp shifter with 10sp RD would give 9 clicks and you'd have to set the limit screws to avoid the top or bottom sprocket. 10sp shifter with 9sp RD would give 10 clicks and you'd set the limit screws to stop it overshifting at one end (effectively cancelling a click).

 

2.) Shifters have the different pull ratio, same derailleur throws. The 9sp shifter could move 0.91mm of cable per click, while the 10sp moves 0.824mm. Both shifters then move 5mm per 1mm of cable pull. In this case, you would need to match the shifter speed to the cassette speed. The derailleurs are essentially identical (the jockey wheels might be different).

 

3.) Shifters have different pull ratios and throws. The 9sp shifter could pull 1mm and the RD moves 4.55mm, while the 10sp pulls .824mm and moves 5mm/mm. In this case, whether you get perfect shifting would depend on the exact ratios.

 

It's possible to get a functional drive train with mixed components, but there's a chance that you will get excess noise and possibly skipping at the ends of the cassette.

A front derailure is not 9 or 10 speed.

 

It is either Two or Triple ... that is it!

The shifter is usually unchanged, but the FD cage width usually changes with the speed due to different change widths.

 

My experience is that I got slow front shifting using a 9sp FD with a 10sp chain, while I get good shifting but a lot of chain rub with an 11sp FD and 10sp chain.

Murphy rules again. I wrote this whole explanation and then found a site that explains it better:

It seems that, within brands, shifting correspond roughly to my scenario 2.

Did you have to bring 11spd into the mix! ;)

is it just me or was all that november chat all wrong. like totally wrong?

 

AFAIK for shifters and derailleurs

sram + shimano fd is compatible

Rd is not at all.

 

speeds refer to the sprocket. and don't forget tha powerlinks do too
