Rated 4.8 out of 5 by 107 reviewers.
Rated 5 out of 5 by Who needs Saint?! I got this mech to upgrade from 1x9 to 1x10 setup on my long travel hardtail. Fitted it yesterday works like a charm. The build quality is really good, setup was effortless. shifting is spot on. and it looks the muts nuts too. Don't get Saint save your money get Zee instead! 19 August 2014
Rated 5 out of 5 low price, great value Used this since 3 months on my Enduro hardtail, 1x10 configuration with Raceface 30T narrow/wide chainring. Precise shifting, only a little hard. Chain never went off the chainring. Great product for low price, highly suggested!!! 19 August 2014
Rated 5 out of 5 by Can't get better than this Only thing that could be better is if the jockey wheels had bearings not bushes. But for the price who can complain. 17 August 2014
Rated 5 out of 5 by Silent but deadly ! my first foray into clutch mechs ...wish i had bought it earlier ...silent solid shifting and zero chain slap or noise 14 August 2014
Rated 5 out of 5 by Good matched this up with a XT shifter and a XT cassette with a Hope T-rex 40 tooth added to it and a 32 tooth Hope retainer ring up front and no chain device of any kind. Haven't dropped a chain yet and shifting is smooth. If you are thinking of running a similar set up on a full sus bike check to see how much chain growth your frame has. I've got a SX Trail and it's at the limits of what it can cope with any thing more and you might be better of with a medium cage. 13 August 2014
Rated 5 out of 5 by Четкость переключения! Отличное соотношение цена качество,простата настройки. Брал комплектом переклюк и манетка Zee под 1 звезду спереди, все отлично встало, работает на ура. При установке пользовался электронным мануалом Shimano.Спасибо CRC за оперативную и качественную работу. Всем удачи! 12 August 2014
Rated 5 out of 5 by Fantastic Brilliant little mech, Doesn't skip (if set up correctly) clutch mech works really well, doesn't bounce around, 11 August 2014
Rated 5 out of 5 by Perfecto para 1x10 Lo he instalado en mi transmisión 1x10 con piñon 11-36 y es una pasada, los cambios son rápidos y precisos, un muy buen cambio a un precio super competitivo, ademas con el sistema shadow+ la cadena prácticamente no toca con la vaina eliminado roces y ruidos al bajar. Fantástico lo recomiendo. 10 August 2014

Which one?

Hi, I was wondering what the 32-36t stands for, is it for links on your chain or what else could it be? Thank you!

Its teeth on the cassette. If you have a wide range cassette (most mountain bikes do) the biggest cog will have 32, 34 or 36 teeth

Answer: 
Hey, it refers to your cassette range - 11 teeth at the small end, and 36 teeth at the big end.
The 23-28t close ratio is what you'd have on a downhill bike - not friendly at all for pedaling uphill!
If you're riding anything other than a downhill bike, then chances are you've got an 11-36ish cassette (it could be 11-32, 11-34 or 11-36 - it's just saying that the cage will reach all the way up to a 36 tooth gear), so get the wide ratio option.
Be warned, however, that this mech will only work on a 1x10 set-up. ie. you can only have one chainring up front on the cranks, If you have a front derailleur at all, then this won't work - just get an SLX mech in this case.

Answer: 
The '32-36T' stands for 32 to 36 tooth. It's the wide ratio version of the Zee derailleur, which will accommodate rear cassettes with large sprockets of between 32 and 36 teeth. So if you're running, say, an 11-34t cassette, your largest rear sprocket is 34t - so you'll need the wide ratio mech. If your cassette has a large sprocket of between 23 and 28 teeth (generally a pure downhill setup) go for the close ratio.

Answer: 
Yes with a but. You either have to get one that has the slightly longer bracket or get a normal one and change the bracket yourself. The picture is of the new bracket details.
Any dealer in the UK that is stocked via Madison can get the part for you (Shimano part no. Y50Y89010)
When you change it, please ensure that you remove the E-clip before attempting to remove the hex bolt.
Once you have the appropriate bracket version of the Zee mech it will work extremely well on your Stinky as it has on mine for nearly 2 years now.

Answer: 
No; SRAM mechs use a 1:1 ratio cable pull, while Shimano runs 2:1, so a SRAM Shifter will not work with a Shimano rear derailleur and vice versa. You will have to use a SRAM rear mech with a SRAM shifter.

No. SRAM shifters have a different pull ratio to shimano, so they are not interchangeable. You will need a 10 shimano shifter.

Answer: 
That's exactly the set-up that I have, and having run the Zee shifter first, I can tell you the Saint shifter is noticeably better - shifts are snappier, lever feel is lighter but more positive, and you get the double-downshift. I'm running an SLX cassette, and overall the shifting is at least as good as my previous 10 speed Sram X9 shifter/XO mech, with a much lighter feel.

Answer: 
The Zee mech is designed as to be used with a single ring only.

You may be able to use this for a double but the ratios would be very restricted. The maximum front ring size I would recommend would be 34 and a maximum of 32 on the rear.

Answer: 
No as the gap changes between 9 and 10 speed and it would never mesh correctly,shimano also changed the pull ratio on 10 speed so you can't even use 9 speed shifters on 10 speed mechs.

Answer: 
No, that won't work at all. You'll need a 10 speed cassette and chain - something like the SLX stuff I've added.
However, you might be able to run the Zee mech with a 9 speed shifter - provided there's enough clearance in the cage for the wider 9 speed chain.
