Which would be better for me on a 27.5 and SRAM eagle, on one hand, I have a lot of torque with eagle gear and a 32t but I almost never use my 2 largest cogs, I also been kinda wishing for more range on the bottom gears, would a 34t be the way to go or not?

Edit: also anyone have experiences with burgtec rings, they look really nice, but I been unable to find anything about their quality

A 34 tooth chainring will give you more top speed.

My friend wanted to change his 30 tooth to 32 chainring on Shimano set up. His
LBS couldn't get hold of original Shimano part so supplied him with Burgtec and he is happy with it. I saw it while out for a ride, looks good and was 25% more expensive. Can't comment on quality as he only fitted it yesterday.

They do lots of components so checkout reviews on their other stuff for an idea of how good they are and Burgtec seem a popular brand, in the U.K. anyway.

I would want a 36t if it would fit your frame. I run 36t with an 11-40 cassette and sometimes wish I had one more higher gear. You should be able to climb anything with that 50 in back.

I would recommend no bigger than a 34. With eagle you'll still have tons of range for the fast descents and have the bailout gears when you need them climbing. A 36T will negate the low climbing gears of eagle. Ya you'll have great top speed but if you're not severely lacking on that side then the 34 should be your sweet spot. Most everything I ride minus lift access is all long steep climbing right from the trailhead. I swapped from a 32 to a 30T and it's the perfect balance for me. If you're rarely using 1st or 2nd gear your balance with a 34T should be money.

Voler-1 is not using his 2 biggest cogs, going from 32t to 36t will have a similar ratio in his 11th cog as he has now with his 10th. He still won’t need the 50t, but will be able to go very fast with 36t front and 10t back. My smallest rear cog is 11, and like I said, I sometimes run out of high gears but not low, climbing gears.

Make me wonder how anyone was able to climb with 1X back when 42t was the biggest cassette.

I’m running the GX Eagle drivetrain and just purchased the 34t chainring (currently running a 32t).

Would I need to add chain links?

Usually not unless the chain is already setup too short

Been saying this time and again, Eagle is bloody pointless, can't see why anyone needs a 52t on the back regardless what chainring you run, had xx1 eagle on last bike never used the last two gears either, stopped following the trend on the new bike n switched back to 11 speed n much happier, lighter, cheaper and XTR shifts smoother than eagle anyway imo. At least the marketing clowns hopefully won't be adding even more gears any time soon though with gearboxes on the horizon... Sram just seems in a dick measuring contest against Shimano, upping gears and tooth counts to say they have more range and all the sheep are falling for it. Couldn't be more happier switching back to 11 speed, coil shocks and 27.5 wheels... Take your latest and greatest air shocks, million percent range and wagon wheels elsewhere because I don't need it, in fact I rather not have it even if it was cheaper than what I run now.

its definitely got its place, more range is always welcome, you can always increase the chainring size and get better top speeds. using the 52 gear with 32t chainrings is there for weaker climbers, as not everyone is a great climber.

My RM Altitude came with a 32t chainring, and the original chain worked fine when I switched to a 36t. I bought a new chain because I thought it would require a longer chain. Four years later, the new chain is still in the box and the original is still working fine (drivetrain is Shimano XTR).

you might try Sheldon's gear ratio calculator. Enter your current setup numbers, pay attention to which gears you're using now and their drive ratio, then enter the new chainring and see how things line up Smile

Lucky man, I will wear out a chain in less than a season.

Depends what you ride. Eagle comes in pretty useful if you have several thousand feet of vert on a transition. Even for a strong climber you want to save your legs for the down.

I'm living in the Netherlands and we hardly have any hills here, heaps of MTB single-tracks ( more than 20 trails between 8 Kms and 23kms long within 25mins in the car) my Sram eagle 1275 10-50 cassette has got heaps of wear (buurs on the tooth ramps) on the 16, 18 and 21 tooth gears. I've ordered a new light carbon Roval sl wheelset and a fresh new sram 1299 10-50 Cassette and xx1 chain I nearly never use the 3 largest low gears on the eagle cassette so to mitigate the excess wear on the cassette cogs 16, 18, 21, should I swap the standard 32 tooth eagle chainring for a xx1 36 tooth? My idea is that my sweet spot for 90% of my rides would then be in perhaps gears 21, 24and 28 which if I'm guessing correct would mean less wear on my rear cassette as there are more teeth to greater disperse the friction and wear thus extending the life of my drivetrain. To be honest I find myself changing gears so unnecessarily often around the 12-18 kph speed it's like the ratios are annoyingly close together that rolling over peaks in a pinch climb I nearly always double click 2 gears up sometimes 3 gears as I transition from climb end to begin a slight downhill in undulating terrein. Would having a larger chainring also stretch the gear ratios a little? It would be great to hear your opinion.

My bike came with a Sram NX 11-50 cassette and a 34t ring. I had the same issue with not enough high gear. Recently I upgraded my bike to an E*thirteen Helix R Cassette (9-50t 556% range) and a 32t ring, this setup gives me plenty of high speed gearing, as well as a nice climb gear. Another combo that is nice is a Sram 10-52t cassette with a 32t ring, although the 52t can be a bit overkill.
