My man, for the love of everything that's holly, please grease sliding surfaces before installation. It hurts my soul seeing that bushing go in dry.
Auch in Deutschland reinigen und schmieren die Lagerung.
You're right - that was a mistake on my part.
Sweet. I swapped out the stock bolts on my XX1 AXS with oil slick titanium ones from Better Bolts. It looks unique and customized from up close.
I've been considering getting some Better Bolts for my brake bolts. How's the quality on them?
@@UmunhumCycleworksQuality is amazing. Never had any issues with their bolts. I have them on 3 bikes. They offer lifetime warranty but I don’t think I’ll ever need to tap into that.
I’ve done this on my NX and an added bonus I put the xx1 pulley wheels as well way better shifting and I can get it tuned properly.
Yup, huge upgrade for the NX!
Great tip! However, you missed step Number 1: Clean everything!
You are right! Definitely should have mentioned that.
We love a toothbrush and cloth cleaning montage :)
Nice idea..the bushing would certainly make a difference.
😀
I think it does! Thanks for watching!
They have carbon upgrade knuckles n stuff in a kit for gx eagles. Stiffer n lil lighter.
Does this work with axs as well?
The point is that it removes play that develops when the wavy washer wears out. I suppose its a durability upgrade but it won't do anything to improve shifting on a derailleur without that play. The XX1 kit is often out of stock so a new washer would achieve the same thing for another several years, GX b-bolt kits can be had for under 10 bones, even skateboard bearing seals work
You're right, this is definitely more of a durability upgrade. However, I do think the shifting is a little bit crisper, although I don't know how I would quantifiably prove that.
@@UmunhumCycleworks You would have to have access to two equally worn derailleurs of the same type, and then replace the b-bolt with the stock b-bolt on one of them and the X01-bolt kit on the other. Then someone else than yourself will have to mount them on your bike (blind test). After trying both you'll be able to tell if there's a difference. Or even better, let your assistant switch back and forth between them until you have statistically significant results 🙂
Does this work on sram rival 1x rd?
Beware, the replacement kit did not "fit" my SX. I was barely able to install it but the bushing is a little wider than the original bolt and when I tighten it up to 6 Nm the mech was't able to rotate any more. Had a lot of trouble getting the "upgrade" bolt out and unfortunately had to go back to the original.
So I have NX eagle and have always disliked the play in the derailleur. It just slaps around. It shifts fine despite the noise. This is my first Sram MTB group-set. I have always had Shimano. Sram road/gravel is just amazing. No issues.
I was able to source a GX derailleur cheap although, I have no idea how worn out it is.
1) would this upgrade reduce the chain slap/movement on NX?
2) would it be just better to go with this GX. I am thinking so.
Just got with the GX - it's definitely better especially if you're not paying too much.
I done the upgrade on one off my bikes and it just stops side play but under pressure theres no movement anyways
What version of SRAM did you do it to? GX? SX? etc.
@UmunhumCycleworks sram gx ,I was advised to do it when I purchased it and later on I done my sons nx .I found on the nx it made more difference through the gears
Just installed New xx1 bolt today. What I noticed is that there is some play still left as there is like 1mm gap between and it introduces little movement sideways. Hard to explain but hope you understand and can confirm if it’s the case for you.
I have this same exact issue on my 50t GX derailleur. I compared the two bolts side-by-side and the overall dimensions seem the same yet I have that 1mm lateral play along the mounting bolt that you're talking about. I reinstalled the original GX bolt in frustration and am equally frustrated trying to put that split ring back in place.
@@npdcpa it’s so weird that nobody notices that! I’ve been running new bolt but can’t get it switch gears perfectly, yes I can feel difference when changing gear pedalling, but overall it’s more inconsistent.
@@Timotelli Do you have a 50t or 52t (520%) derailleur? I wonder if that is the difference... I switched my 50t back to the OEM bolt which to be honest wasn't a problem until I watched one of these videos. My OCD got the best of me and I wasted money on this stupid "update".
@@npdcpa I have 52t 12 speed GX. Did you try out with new bolt?
@@Timotelli I didn't bother. That 1mm gap just had trouble written all over it. I did try all sorts of combinations of old and new bolt, o-rings, washers, etc and I couldn't eliminate that millimeter.
my GX AXS already came with an XX1 bolt
Yup, this is just for mechanical.
Maybe start with a cleanse every now and then.
Good call haha - I'll make sure to do that next time.
You could have washed that thing while you had it off.
Lol fair point
I appreciate the guide, but there are a few things that are done wrong in here that would greatly reduce the effectiveness of this upgrade.
First, CLEAN EVERYTHING spotless. Youre installing a sealed bush. Any dust in there will destroy the new bush pretty quickly.
Second, it would be a good idea to use some loctite bearing retainer on the bush that sits inside the old housing. It'll remove any play between the new bush and old warn housing, and greatly increase how well this mod works.
Third, LUBE! Everything that moves against something else needs a light coat of grease. I cant believe this guide misses such a simple step.
No offence, but the title is misleading, and the claims about improvement in SX / NX (2:52) are simply not true. This mounting bolt will not improve SX or NX with their composite plastic parts (that will still bend no matter if mounted with higher quality bolt).
Maybe it is just anecdotal, but many people who have done this upgrade on SX or NX have said they noticed an improvement in shifting, but that could definitely just be confirmation bias. Either way, thanks for commenting!
Even if the plastic parts on sx and nx have more flex, this mod still reduces the total play in the system. I don’t really understand your point
That is my thinking as well.@@SeaCowsBeatLobsters
@@SeaCowsBeatLobsters My point is that the flex of the parts in SX / NX is so big (compared to the play on the bolt itself) that you will not notice the benefits of this mod. IMO, for SX and NX the much better solution to increase shifting precision (in terms of "bang for a buck") is replacing the guide jockey wheel with one from a higher SRAM groupset (or using some 3rd party, i.e. SunRace) that uses bearing instead of a metal bushing. That's what I did for my SX RD, it's working much better now, still far from perfect, tho.
The best you can do is switch to Shimano
I do think Shimano shifts a bit smoother overall, but SRAM AXS wireless is pretty awesome.
