[@yaterlynch6477]

Glad I’m not the only one who went back to 2x10. The chainline and stretched out rear derailleur on 1x always drove me crazy. I prefer 2x xtr/xo mix for marathon racing and all day rides.

[@akifhossain2587]

That's also the reason always makes me confused to shift in 1x, while using both higher & the lower sprocket seen so much stressed in 1x

[@justdude8115]

I like my double with 36/22t chainrings. On the road I never switch to smaller chainring, and on offroad I never switch to bigger. It's damn perfect setup.

[@ImHar2]

For me too, the best setup is 2 X 10, I don't change it for anything, I never go back to 1 X 11 again. The 2 X 10 covers both flats and roads as well as mountains.

[@deusexaethera]

1x12 will go down in history as a mistake.

[@yaterlynch6477]

@@deusexaethera yep…range, chainline, terrain, etc was an afterthought. They were so focused on making a single chainring work that they whiffed on the rest of the system. The 1x11 (32x42) low gear is proof. And 32x10 is spun out on open sections especially marathon races.

[@cesarecannavo1134]

Great video recension Paul, many thanks.. I am new in your great Canal. I have learning too much.. I are one older bike mechanic that to beginning from disc brakes, I stopped fitting bicycles. Practically 10 years later, I would like to assemble the new frame and fork set myself. Your videos have given me a lot of confidence. However, the part where you mount the chain, I saw that you shortened it without having measured the length. Basically the front chain was on the new 30-tooth sprocket. At the back it was on the 11-tooth sprocket. The most absurd thing for me was that on the pantograph of the rear derailleur (Shimano XT part), there is no longer the pantograph adjustment screw, and in addition you only put it under tension with your hands, pulling it a bit and putting it under tension. At one time I remember, you used to pull it with pliers to put it under absolute tension. Greetings from Switzerland. Goodbye (*_*)

[@PaulXchannel]

Thanks for watching.

[@ianraybetron4300]

I've gone back to my 2 x 9 system from a 1 x 11 system because of cross chaining and fewer gears. My chain started creaking on the largest cog...thought it to be dirty...only to realize that it creaked because it is cross chaining...putting strain on its individual rivets. Though its only 9 speed..11-34 with a 38-24 front...my drive train is more stress free than my 1x 11-46 set-up.

@@radiocontrolled9181 or... 2x7 vs 1x12 :)

[@mattjns]

@@radiocontrolled9181 I see you’ve wandered through a bunch of comments leaving your 2 cents. In response to your statement here, no, you don’t really have 21 gears with a 3x7 etc. On paper you might think you have 3x7 = 21 gears, but in reality, much less. Consider that: "twisting" the chain. For example the front big gear and the rear big gear affects the yield of your pedaling and also the life of the chain, so you won't do it too often, I know you get that grinding sound on your Tourney, I know it. 😉 And some of the combinations front-back are so close that they are practically redundant you end up having like 8 or 9 actual speeds.

[@radiocontrolled9181]

@@mattjns My drivetrain is very smooth because I keep it clean, lubed and well adjusted. It works perfectly and is quite silent too. Yep, it's not 21 gears true. But I can safely tell you that I use 16 of them regularly with no grinding or issues. The cross chaining issue exists for the 3x and moreso for the 1x. There was a time when this cross chaining subject was very popular and very much discussed and debated. But abracadabra! once the marketing gurus came out with the 1x 'invention' ..... Puff!! It vanished and they no longer mentioned it. Why? Hehhe not because it vanished but because it''s not in their interest now to speak about it anymore 😉 But it's still there and in some cases even more pronounced than with 3x drivetrains.

[@mattjns]

@@radiocontrolled9181 Good to hear! Well I guess that’s you opinion I’m happy for you to have it. I recently swapped over to a 1x11 on my mtb. I had a 3x7 that I ran on the middle ring 95% of the time anyway. The no frills / quick shifting on trails on a 1x is no joke. And I’m curious why a lot of people think chainline angle is extremely exaggerated on a 1x ? I mean, yeah, maybe a little. My mtb is literally upside down next to me in my living room (my wife’s away, I’m not stupid 😉) I had my old 7x cassette in my hand holding it up to the 11x just prior …….and I mean, the largest sprocket is almost in the same spot. Maybe the 11 is like 5mm closer to the spokes? Tops? Anyway, works for me. I also love the clean look of a tidier bar setup and no front derailleur. That’s just me. 👍🏼

[@user-du6op6qx5s]

[@tsongvlog4128]

Woooww😍 I wish I have it that too.

[@battistaverardi1240]

I've done the same conversion. But Just recently I went back to 2 in the front and ten in the back. In my opinion it keeps the chain more symmetrical or straight when you can switch between the gears. I find that one in the front and more in the back keeps the chain at more of an angle. I just have a better feel when you can keep the chain straight by switching from small to big and vice versa. In my view one in the front is just fad and you can never beat the " old school". But each to their own.

[@abdelrhmanyussef4143]

I agree with you, the small gear in front with the big gears in the back 1,2,3,4 and the bigger one in the front with the smaller in the back 5,6,7,8, i believe its make the chaine less tension that way.

[@johndef5075]

Me too. Now I have the range of a 52 tooth cassette with much tighter ratios. Like it better and not noticing slight weight increase at all.

[@radiocontrolled9181]

Of course! I never swallowed the media marketing bullshit lies that going from 20 gears (2x10) to 12 (1x12) is an 'upgrade'. Vice versa it would make much sense of course , , , , but most people are fed lies and they swallow them like a fish swallows its bait. I will stick to my trusty old school 3x7 which shifts super smooth with a cheap Tourney derailleur. Just converted the rear wheel from Freewheel to Cassette coz I kept bending/breaking the rear axle.

[@rollinrat4850]

1by is ok for really rough trail. However, if you know how to ride or shift, you know to keep the chain in large numerical size gears to keep the chain wrapped up. If you do more than one genre on your bike such as riding paved roads to get to trails you will inevitably have either too low gears or too high a range of gears. Not only that, the jump between each gear makes it difficult to obtain an efficient spin at many different speeds. One by costs more for less and wears out components faster.

You do NOT need a chain guard as the rear derailleur has a clutch.

[@3Dmaking]

LOL shortening you chain like that is the recipe for ripping rear derailleur off or bad shift quality. You need to RTFM 😉 If you a on a limited budget you should have considered choosing the SLX rear derailleur and the XT shifter as you’d get better functionality at the cost of a bit of extra weight. I fully understand that the choice of rear derailleur and shifter you made looks better.

You use a tork wrench on the bolts for the chainring but not on the crank arm and no grease on the pedals thread. That's a little weird. But i like how you made your own bolts.

Call me crazy, but for a budget upgrade, I like prev gen SLX 11sp + new SLX derailleur and Deore m5100 cassette: the range is the same, parts are cheaper, and the Deore 11-51 cassette is lighter than the Sunrace CS-MZ800. You have one less cog in the middle but to be honest, I've ridden the SRAM SX Eagle and this SLX/Deore mix and I don't really miss the extra cog and the shifting is even better than SRAM SX Eagle.
