I run 28/50. But not for tech climbing reasons. Its just my uphill recovery gear for when i want to conserve and extend my ride time/distance. 52 would be fine.

I cant say the 50 spins like i dropped my chain. Its still useable. But im moving 255lbs.

I would like to try shimano next time for the hyperglide+.

Fwiw. The 11 spd i took off is identical to the 12 but with a 50 added. So i got exactly what i was looking for.

 

The 50t cassette is still available as an option.

 

I have no use for 52t in the back. Faster to walk.

 

It is not faster to walk. This is bad information. If you were climbing up Old post to the top from Scorpion, it would be better to keep spinning at 3 mph. You aren't going to walk that climb at 3 mph with bike in tow.

It's a shame you post this because you race and you know that sometimes it's faster to Run with the bike , but even the act of dismounting and mounting costs lots of time. Anyone who has looked at a cycling computer while walking knows It's faster to stay on the bike.

Increasing from 50 to 52 is only a 4% increase, you are unlikely to even notice the difference. The whole 52 thing is just so they can claim bigger range than Shimano.

 

You are over thinking it. The bigger issue is, can you balance with your baby on 20% grades while going so slowly that you are in - 28/50.

Steep grades pitches are usually not what causes the use of a granny gear, it’s long climbs of a challenging grade.

I prefer my 9-46 e13 cassette shifting and spacing to Eagle xX1 10-50. I run both with XX1 chain and GX eagle mech and shifter. I do about 5k miles per year on my MTB and ride hard, but I shift properly and don’t tear apart my cassette in that manner. I can usually get them for around 200 with online coupons.

I live in the flat lands of Ohio. I have 30x50 with nx eagle. We have lots of short,steep, rocky roots hills here. Being a perpetual beginner since 92 I appreciate the pie plate in the back. On top of that my quad still hasn’t come back after knee surgery over a year ago.

I’ll spin the hell out of that 50 tooth and still wish for a 28 tooth in front. Half the time I still don’t make a climb just because either I don’t have enough momentum, or my right leg is just smoked. I’m tempted to see if a 28x52 would work.

I want to ride much harder trails on the east side of Ohio. Much longer climbs with steeper hills than the west side. I’ll need conditioning of course, but I’ll still need gears.

 

Weak old farts like me love the 28x50 gearing for recovery on long hills. While 28x10 on the other end is adequate for what I do on the trails, I do ride on pavement a fair bit to access the trails and for that I wish I had as much as 32x10. While it's not worth the cost to switch if I were getting a new bike I would put on a 30T ring with the new 10-52 Eagle in preference to to my older 28/10-50 set up.

 

You would be super happy with the e13 9-50 cassette if you have XD

I'd buy the Leonardi NPU (the one with only 1 gear in Al) 9-48 cassette. Shifts beautifully, better gear spreads than Eagle and a wider range.

I can hustle at 3mph up a 10% grade no problem.

 

No you can't....

Not this hill, or any of the others around here that are on the 80 mile route we are gearing up to do This fall.

Those minutes add up.

Also, I'd rather not wait on you walking while I'm riding with you. If you are off the bike, you are cooked and aren't "hustling" anywhere.

I ran a 28/50 on an Epic for a 24 hour race. At the end of the day I was still on my bike going sub 3MPH on the big climb "Dam Climb" (9% for 1.3 miles, pitching up to 20%) passing people who were walking.

I might try the 52 next time around on my E29. I am running a 32 right now up front, thinking about getting a 30 but I do actually use the top end of the 32 on occasion (especially for some high speed jumps at the local park). The 52 might be better to allow the 32 up front and still get that little more for the harder climbing.

 

The poll should include the new Shimano 54T (divisible by 3 therefore not a 52, or 53)
CS-9120

 

Any time you change gearing, you have to change how you ride and how you utilize gears.

50 to 52t up front isnt enough of a jump to change the front ring up one size, so it works best if you existing whatever front ring and 50t rear is juuuuuuust a hair too hard. You'd find the 52t perfect. Or you're kind of on the edge of it being too low, you can pair the 52t with the next step up in the front.

 

We climb canyons, multiple in one day, often each climb is a 1000 feet and riding 30 miles means 4000 feet of climbing.

I did a 32 oval and the 10-50 for a year, and then went to a 30t oval. At the end of the day that 30t made it easier to climb the rocky rutty 1/4 mile steep grade.

Lots of BS over 2t on a rear cog, Id add one when I wear out my 50, the 2t wil be welcome since it changes so little

 

Has SRAM fixed the chain riding up on top of the teeth with the new 52T cassette?

 

That is an error in setup/adjustment. Probably need a tighter gap with the B-tension.

 

I run 34 with 10-50 and 2.35" 29" tires.
It's fine. There's definitely climbs where I've go really hard for some sections thought (but i like the 34 on the fast downhills). This because if i dont I will lose grip.

That said, having just a little more with the 10-52 would be fine too and probably a bit more versatile. The gap doesn't bother me because when I'm on the last cog it's because the climb is super hard anyway and I'm not spinning at 100rpm, more like 50 or 60. This means that worse case scenario, i'd be spinning a tad faster which is anyway .. better.


All that to say, I think the 10-52 is micro-optimization but it doesn't mean its a bad cassette. If you've a derailleur that can handle it and money is no object, i'd just get it - specially if you have big grippy tires. Else, not a big difference. Heh I'd almost get the 10-52 just because copper looks cool.

 

I run a 34 on front and never use the 50 on the rear on the trails I ride. Why on earth would I want a 52 tooth in the rear...it's heavier and shifting isn't as good? For my trails and my power, the 10-42 11speed cassette was the best for me.

 

if you ride on flat trails and you like your setup you don't need to change at all. The weight diff is ridiculous so that's a non-factor. Like I said before, as an upgrade other than micro optimization or cool looks it doesn't really make all that much sense (specially that you've to replace the derailleur in theory). As new bike though, I don't see any down side.

 

It is only a known issue if you don’t have it adjusted correctly. 😄

 

Thousands of miles and probably near a million feet of climbing on Eagle, I haven't had that problem.
