Greetings all! I've recently returned to the world of mountain biking and picked up a 2019 SC Tallboy C (R build with NX) and have an opportunity to get a considerable discount on a new XX1 Eagle drivetrain (chain, cranks, shifter, derailleur, cassette). In the interest of full disclosure, the NX my bike came with is perfectly fine for the time being and adequate for my skill level--but I'm not sure if I want to pass on the opportunity to upgrade to XX1 with a generous discount. The kicker here is I can't get the XO1 at a discount but I can get the XX1, but my question is on durability and my ride weight (205lbs). Of all the googling and youtubing I've done, it seems that XX1 and XO1 are constructed similarly with the primary difference being the cranks (hollow for XX and foam-core for XO), yet SRAM markets the XO1 groupset for trail and enduro buffs while the XX1 has the XC label to it. However, SC offers both groupsets for the Tallboy so it's evident they feel confident offering the XX1 on my particular ride. I ride mostly single track trails without any major drops. If I could get the XO1 at a discount I'd go that route, but as I stated earlier, only the XX1 is available and I'd have to pay more for the XO1. Any thoughts on overall durability for my particular application? Many thanks! #1 · Sep 4, 2018 (Edited) Greetings all!

Less weight and slightly better “feel”. I would recommend you ride what you have and replace things as they wear out. The xx1 groupset is nice, but unless your a gram counter or racing it’s just bike bling. Also have noticed the xx1 derailleur needs more TLC than it should. #3 · Jan 26, 2019 I've ridden for a long time and always had Shimano. My first SRAM was on new 2018 Kona in sig. It's GX Eagle (12spd) and like how it shifts but long cage design is prone to picking up debris and I've already had to replace it once at $110. I was shocked how much the 'upgraded' XO/XX versions are. Not worth that much to me so I went with another GX. When drivetrain wears out I'm looking into to 11spd setup Shimano setup due to the more traditional cage design, good reliability, performance and reasonable price. #4 · Jan 26, 2019 I weigh more than you and have been using XX1 for 18 months problem free... don’t worry about the “enduro vs xc” marketing bs. But... if you have NX currently, do you have an XD driver on your rear hub? I seem to remember NX being different. #5 · Jan 26, 2019 I'm a big X01 fan, the stuff is extremely nice and when you step up to that level, you basically get all the quality of XX1 IMO. The derailleurs and cassettes are super-nice. I'm 11spd, but if it's anything like this, the 11spd X01 cassette is the exact same weight as the XX1, only difference is the finish, and the derailleur is very rigid (good for crisp shifts), a definite improvement over the GX/NX levels. Also, those foam-core cranks. I had a set of old XX1 which were foam core, basically the new X01, I beat them to hell for years, including DH racing, enduro racing, park days, slamming into rocks, all sorts of stuff. Over 5 years, they took a lot of abuse. I finally ended up breaking one when I slammed it into a root at high speed. The thing is that these held up to infinitely more abuse than my Race Face Next SL cranks. They are both carbon cranks, but they couldn't be more far apart in terms of how durable they are. Both of my Next sets have failed and that happened in about a year's time. Being a bit heavier or more aggressive rider, you'd probably be well served with the X01. To replace my foam-core XX1, I got the new X01 and moved the good XX1 crankarm to my fatbike to replace the broken Next SL. I'm not sure there's really anything to be gained by going XX1, unless you are looking at dropping a few grams at the cranks and you know you won't be hitting objects much or you want it for XC racing and just to shave every possible gram. #6 · Jan 26, 2019

The big difference is the op can GET discount on the XX1 why wouldn't one go that route. His XC riding style makes perfect sense to get the XX1.

Yup, still waffling. #11 · Jan 27, 2019 I have been thinking about "upgrading" to 12 speed when my 11speed stuff wears out Biggest reason to do the full shifter/derailleur upgrade the next time my cassette wears out would be if I truly believe I need more gearing range. with my 11sp the way I have it geared, the only time I wish I had more gearing is when I am rolling along the road on my way to the trailhead. Sure, if I had a bigger ring up front that would fix that, but then I would be suffering on the climbs more then I want to. So I could go to 12sp with the huge cog on the cassette, be able to then get a bigger ring up front and have the best of all worlds. That would make those 5-10 minutes I spend on the road going to the trail head reduced to 4.5-9 minutes as I can go faster then! Hopefully I can gold on long enough for the new 13sp stuff to come out next year. 1 Reply #13 · Jan 27, 2019 This is for my trailbike build. Currently still on 10 speed, X0 with a 11-40 Praxis cassette with a 34 up front. Don't really need a lot more than what I currently have. A bit more on each end would not hurt. Top of the list is X01 cranks, 11 speed shifter and derailleur, with a (SRAM / Garbaruk / E13 / ??) cassette to be named and a 12 speed chain. This will most likely be what I end up with unless somebody comes up with a good reason why not. Insert Quotes Post Reply
