Cheapest way to convert 1x9 to 1x10

[Demodude]

Hi guys, I'd like to do this switch without spending a ton. Current setup is a SRAM 1x9 on a Spec Enduro. The cassette is 11-34 so I'd like the 11-36, which 10 speed cassette is least expensive. Also thinking about the type 2 rear dérailleur .. Any help is appreciated..

Am I correct that the items needed are:
10 speed chain
10speed cassette
10 speed rear der
10 speed rear shifter (w cables)

Ie: the front chainring can stay, correct?

Or you could get the Shimano HG-61 12-36 cassette and keep it 9 speed...that'd be the cheapest

Holy crap, that is cheap! I love mtbr, thanks. Is there any problems using shimano cassette w a SRAM rear derailler and chain?

[wschruba]

None whatsoever, have fun.

Will this cassette work on a non 29er hub? I have a 2011 Cannondale Jekyll 4 MTB. Not quite sure what kind of hub it has. Product description warns not to use on hubs other than M529 or M629.

Hubs are not 29er/26er specific. So yep, it'll work.

Just watch your chain length. If the original chain was just long enough to fit 34 teeth, 36 might be too much.

[Sickmak90]

How much of a difference do you all think the 32/36 combo would make vs a 32/34?

I was considering a 1x10 setup also, but this is definitely cheaper and much easier.

Will do. With my largest chain ring removed and replaced with a bash guard, it shouldn't be an issue I pressume.

That is good news. Thank you!

I am running 1X10 with a 12-36 on my Quiring hardtail, and a 1X9 with a 12-36 on my IRD Tempest hardtail, and there is really no difference. The only place you want to be careful is if you are running 3X9, as according to Shimano, on the 22t granny and the 36t cassette, you can blow out your hub (which I doubt will ever happen).

You must not weigh 240 pounds. Shimano freehubs are built with exploding pawls. Good thing they're cheap. Disclaimer: I've never used the micro-ratchet freehub

I usually weigh around 210#, but I haven't used craptastic Shimano hubs in YEARS

Aren't the SRAM 9 speed rear derailleurs limited to a max 34 tooth ring?

I am running 11-36 on a medium cage X0, and it has been flawless.

What is it on the derailleur that would limit the cog size that it can accommodate? I'm serious... I don't know the answer but it's relevant because I might put a wider range cassette on my wife's 1x9.

I've always gone with the shortest cage option for my 1x9 setups and they've worked very well. Shorter chain, slightly more chainring wrap and better chain tension are all wins. Right now I've got two - one is an XO short cage with an 11-32 and the other is an XO with a 12-25.

[Demodude]

So, I recieved my 12-36 off eBay and mated it to a short cage SRAM x-9 rear derailler and can say that everything works flawlessly. I'm so happy I didn't have to shell out $300 for a new shifter, cassette and derailler

[41ants]

Bump... Will this setup work with an sram short cage rear derailleur

Should work with no issues if you get your chain length right.

...snip...

The location of the top pulley/cog on the derailleur "arm". A large cog eg 36 can hit the top pulley. Adjusting the B screw can help. Usually manufacturers are conservative in the max size recommended and you can go 1 or 2 teeth bigger on the cassette. It is also possible to get smaller cogs/pulleys.

[cyberavner]

Another thing to try is replacing the B screw with a longer one (if the adjustment is maxed out).

[Demodude]

I took off the 12 cog and replaced it with an 11 tooth from an old cassette. So I effectively have a 9 speed 36-11 cassette- winning!

This is a great thread.

I have a quick question on my chainring.

I have a 2013 XXL Rockhoper comp 29er and I changed the chainring setup from a 3 X 9 to a 1 X 9. I am running a 38T e-thirteen chainring and 11 - 34 sprocket with th seat pole mounted e-thirteen chain guide. After researching a little and riding for 4 months now I feel that the 38t is not the most efficient chainring. I live in Miami FL and the trials I ride are 50% flat and 50% man made hills and drop offs.(Look up Amelia Earhart Park Miami FL)

What chainring would you all suggest I switch to for my type of terrain? I was looking at a 34T but I want some advice before I purchase it.

FYI I am 190 LBS and 6 foot 5.

Thank you
