40t upgrade. Yay or nay on 16t as well?

iscariot how is the 1x working on the Slayer?

Just got back from another ride. So far so good. The 42t shifts great both on and off the ring. The 16t has very occasional hang ups but it functions okay. I'm still thinking that the 16t performance will degrade faster than the rest of the cassette due to faster wear. I'm looking to put the shimano 16t on. I think that's a better long term solution both for shifting and for durability.

As far as riding performance goes, I currently have the 30t NW up front, and with the 42t out back, the gear inches are about the same as the 24t granny with the 36t rear I was running in 2x mode. I only lost 1 gear inch.

When I hit the 42t for a technical climb or a long steep gravel road slog, it performs so well that I don't notice a difference between 1x10 and the 2x setup I had before. If I end up having to push up a section now, I would have had to push up that section before.

The cool thing is that I'm actually cleaning more climbs than before. Completely psychological. I figure I have 1 less gear inch so I better really hoof it up this climb. And I end up making a lot more climbs because of the extra effort I'm putting in.

There are several times where I would like a 32t up front, as I've spun out on descents. There are times when I'd like to throw in a few strokes here and there, and when I do, there nothing to push on. Right now it's not a big problem. I have a feeling it will be more promenant once I get shuttling (next week) and start riding resorts once stuff starts to open up.

tl;dr

Overall, definitely worth it so far. Long term is still to be determined.

cool glad to hear. I'm keen to swap over, might wait till its time for a new chain ring though.

The most accurate way to do this is to remove your rear shock, and cycle the suspension/linkage.

Take whatever point in the suspension cycle that uses the most chain length and add a link or two from that. Then its impossible to run out of chain and bind your derailleur.

Monkeyed around with this a bit yesterday. After removing all the air in the shock, here's where I wound up under full squish...



I think that should work out okay. Adding one more link put way too much slack in it when the chain was on the 11 cog. Shifts are clean in the stand and rolling along the street. Hoping it works on the trail now.

Sorry to be the bearer of bad news but some of the problems you've encountered are likely because of the short cage derailleur. You can't run a short cage, they don't have enough range. You can away with it with a 11-36 cassette but 11-42 is way out of it's range. You need to run at least a medium cage for consistent performance. Long might be better but I wouldn't want to do that myself.

I'm using the 40, not the 42, and have seen plenty of photos floating around from both OneUp and twenty6 that are using a short cage. I'm still on the fence. Going to spin it around a bit more and see what happens.

I've seen guys using the short cage Zee and making it work.

FWIW I'm using a med cage X9 type 2 (clutch). I don't know if I mentioned that or not.

Don't know if you tried this, can't tell from the pic. So... Shift the chain up to the 40t/42t and reduce B-tension until you get rubbing (between the pully wheel and the big cog) and it won't shift. Then back it off a half turn or so (To clarify: add about a half a turn of b-tension so it is just about to rub, but isn't actually rubbing).

This will give you max chain wrap around the cassette, and will put the rear der in a better position when using the 11t cog. You might have to make a slight secondary adjustment when its on the 11t cog.

Haven't read through this whole thing, but anyone go with a Canfield 9t microdrive as well? That'd be so enduro!

Not running this personally, but it is doable with a med cage SRAM clutch derailleur.

Still sounds like a stretch to me as I recall my short cage was near maxed out just with 11-36, but I did like the short cage. Sounds like you've done your research though, carry on, and good luck getting it sorted out.

[iscariot]

The more I ride it, the more I like it. As the season progresses, I'm getting more fit and therefore stronger at climbing. I will likely give the 32t NW front a try soon (currently running 30t NW front).

Sooooo Im back to being stoked again. Ordered the RAD cage from one up and it definitely solved the shifting problems with my XT derailleur and the 40t add on. Fucking stoked to ride again.
The install video was pretty straightforward and went really smooth. I can see how it could be very intimidating but I was able to do it no problem and I have zero pro mechanic training.

The for the heads up, I'll order a rad cage. Shifting has been good on both of my one up 42 setups, but I like the idea of running a regular orientation on b screw.

Anyone find that running a longer chain for extended range (using 42t) adds enough extra slack to the system in the smaller cogs that they need a front chainguide? I've tried adjusting the clutch but the shifting just gets really stiff.

B-tension adjust fixed that for me without the need for running a guide with a RF NW up front.

Basically dial out the b-tension until the bike won't shift into the biggest ring in the cassette because the upper pulley wheel on the derailleur is making contact with it. Then add b-tension a quarter turn at a time until the pulley wheel just clears the big cassette ring. This will move the derailleur forward relative to the rear axle, and take up the chain slack when in the smaller cogs of the cassette.

Had X01 on my enduro and really liked it. Just got this kona process and had a bin of parts left over from another bike, so I ordered up the one-up full setup (42,16, rad cage) and really dig it for the price of upgrading an existing drivetrain. Doesn't give up too much to the 11 speed, and I like shimano shifters better so I'm stoked.

B screw is out as far as it can be (w/Rad cage). The clutch can't get any tighter before shifting deteriorates. I wonder if the Sram XX1 NW ring is getting worn out after 1300 miles.

Congrats on your new bike. That Process looks siiiiiiiick.

I wore out my XX1 ring in 300 miles of pacific northwest spring riding, the chain barely showed any wear. I replaced it with a Blackspire NW ring that seems to be more robust and has lasted much longer, thought the conditions have been better. The one draw back to a 1x system is the front ring takes all the wear.

How did u know it was worn?

I had a horrible grind noise under load, in the stand it couldn't be duplicated. I Checked everything else it could possibly be first. Finally I took the ring off to clean it and inspect it. It was obvious at the point and was more visible from the inside for some reason. The leading edges where worn in pretty bad. I think its laying around still I will go see if I can take a pic.

[Eluder]

Here is from the back, way more obvious on the non wide teeth.

Wholly moley, I hope I don't have that problem. I just picked up an XX1 rig Friday and almost have that much mileage on it already. I ride a shitload and don't want to be replacing stuff left and right.
How often do you guys replace your cassettes and chains on XX1's?

[Eluder]

Cassette and chain still are great. I only use the aluminum 42t when I need to. I figure it would be the first to go, but it does have the most wrap so that helps.
