Looking for a new rear derailleur...
« on: April 26, 2014, 10:47:46 AM »
After this past week of riding I have decided to upgrade and modify my rockhopper a bit... I am going to switch to a 1x10. I would prefer to stay with shimano and want to try a clutched derailleur. I don't need an XTR, so how far down the line have the clutches worked their way? I realize that a new cassette, shifter, and chain will also be in order as well...  Thanks for any info you all can offer...

The Shadow+ RD's go all the way down to SLX.  However, keep an eye out.  I just saw a XT shadow+ RD for $100 on the interwebs.  Clutch RD with a N/W ring is the poo.  If you are currently running 9sp, you can just purchase the RD and keep the rest.  As far as I know the N/W rings will run 9sp.  I have both a Wolftooth and Raceface.  If color is no concern, I'd get a WT, american made goodness.

The N/W Woolftooth ring I have works great, and I am still on 9 speed. No clutch derailleur, still no dropped chain.
I think the 1x10 set ups I have ridden were all great. Clutch RD on a few of those made the bike so quiet it was like a single speed.

Thanks for the info guys! Any recommendations on a chain guide? I believe I will need one that clamps onto my seat post tube and not my bottom bracket. I am thinking I will probably go with a 30T chainring....

Don't need no stinkin' CG when running a N/W ring.  That's the beauty, you're free!!!

Yep- chain guides will soon be museum pieces.  :P  I haven't ridden on anything too rugged yet but I don't even think about the possibility of a drop. 30t here also. Me likey!

So my RF 30t came in last night, and I put it on today. After getting the crank arm re-installed, i spun it without the chain on to check the tracking... the chain ring tracks true, and cranks spin freely. However, the bike has a wiked lil shimmy. Like the drive side crank is heavier than the left. Is this normal, or is there something I should recheck?

when will your crank ever spin that fast?


Never.  Try that with your wheels.  The weight imbalance of your valve stem is enough to set your wheels to shaking like there's an earthquake if you spin them up fast enough.  But you almost never ride that fast and it doesn't make an appreciable difference.


Yes, the drive side crank arm is heavier.  It has a spider to bolt on those chainrings.

Not to geek it out, but your legs will dampen it  out .  The force you introduce in the crank system offsets any inherent imbalance in the rotation mass of the crankset.
