2 by 9 is my setup for long distance gravel riding, I like how you can just drop a gear in the front to climb a hill instead of shifting multiple times on a 1by
Thank you so much for this video! I went full nerd and made my own spreadsheet from what you guys used. Now I can accurately see the difference between 1x and 2x setups before I buy/swap for different races/rides. What I've generally found being a key difference between these, unless you buy an absolute dinner plate of a rear cassette, is weight. Overall, 90% of the time I'm using my 2x setup for all my general rides. Then the remaining 10% of my rides with my 1x setup (with 51t rear) when I'm going on rides that have extreme climbs of 20%+ gradients.
IMO the best cassette to have in the back is either 11 x34 or an 11x 36 9 or 10 speed. 11 to 13 speed chains are narrower. They will wear out faster. So I'll stick with my 9 or 10 speed 2 x setup I have a 8 speed 11x40 paired with a 44/32/22 triple. I sometimes forget I have the additional chainrigs when climbing. My only issue is instead of being in the middle of the cassette I find I am using gears from 11-18 more just to maintain a good cadence. Added to this is I am using friction shifters which allows me to move through the gears quicker and sometimes I over shift. Climbing is much easier now. Moving through the gears is much faster and simpler
1 by is only acceptable on the MTB, there I switched to a 36 teeth chainring because the end speed in the city was too low and I constantly driving on small cogs which are dying faster. I don't believe the 1x is more efficient because the newer 2x are really centered towards the sprocket. Look at the new grx. This things works like swiss clock.
With 12sp, it's quite easy to go 1x if you live in a flat area. I live in a valley with huge HC climbs. But if I'm not climbing, I'm always in my big ring and don't ever touch my 33t on my 10-33 cassette. I have a 56t 1x on my TT bike and only use my 34t(11-34) for overpasses if I hit a red light near the bottom
@@veganpotterthevegan yes it is, I also got 1x on my TT. But these gravel 1x have MTB cassettes which are not great at flat roads, you are seldom at best cadence since the gaps between cogs are so big.
@user-rl3ef4ju9k they don't use a mountain cassette. Live on flat roads? Use a 10-36(11-36 for shimano) or a 10-33(11-34) and you'll have good gear gaps.
@@veganpotterthevegan Shimano GRX 1x set uses 10-45 or 10-51 XT-cassette. Sram XPLR uses 44T cassette but they also offer road 1x with up to 33T cassette. Anyway, I like to have that small chainring for the occasional 10% or more gradient, I can deal with the extra weight of ring and derailleur on the flattish roads ;).
@user-rl3ef4ju9k you don't have to use GRX or XPLR at all. Their longer caged RDs will clear up to a 42t cog with many hangers. I train with an 11-34 on my TT bike and have a ton of b-screw left with my AXS rear derailleur. It can clear a 36 easily with where I need to set it just to avoid having the cage hit the spokes. This is with a 56t chainring for my TT bike. On my road bike, I run a 32/48 with a 10-36 and I'm really only using the small ring on very long climbs. If it's a 10% kicker, I'll stay in my big ring.
You are wrong because 2x is faster at that, but 1x is better at trails because you dont need heavy gears so you can just use a granny chainring without worrying about range or your front mech getting clogged
2 by all the way, 1 by makes no sense for a gravel bike. 1 by was created for MTB that endure lot of shocks and frequent changes, to prevent chain drop. Gravel bikes dont experience what extreme MTB does. These gigantic one by cassettes are expensive, and heavy, because of the multiple materials required to get them to an acceptable weight (steel, aluminum, titanium, carbon). 1 by also requires the necessity to sweep across a large amount of cogs in various situations. And of course engenders large chain angles. Snicking up and down your front chain ring at an intersection or before a climb is so easy comparatively. And lighter. And less expensive Fashion trumps common sense though unfortunately. Producers will continue to flog them and dummies will continue to buy them :)
No. 1x is loved by people who want the smallest number of movable parts on their bike. Fact is I don't need 20+ gears with 5 of them being equal. I just need a slow gear for the hills at like >1.2, to a fast gear that'll get me close to about 40km/h ideally. Not many in between needed. I also don't need carbon, fancy shifters, wheels, brakes... If I had that many hills around me I'd probably get an electric bike or just get off and push instead of wasting energy.
Absolutely love my 1x set up. The simplicity adds to the joy of riding. Wouldn't have it any other way.

Too much jump between gears for me on a 1X. I like specific cadence which is best with 2X

2:55 there are actually a total of 5 gears that are close leaving only 12 gears in total. So you could achieve the same thing with a 1by no?
2x is perfect for long rides. Perfect!

All the disadvantages for 2x are not an issue for most folk with well maintained bikes.
The main disadvantage is the rider itself 😂
I'd frankly like an XC bike with a 2x crankset and 11 gears on the rear wheel.
Just today ordered 2x for my new frame set. Our roads are pretty flat and smooth so speeds are high and need close ratios like on road bike.

2x always! How is this even a discussion?!
1x seems best for people going up/down on trails all the time so they're either going fast or slow, so big gear jumps aren't a big deal.
You are wrong because 2x is faster at that, but 1x is better at trails because you dont need heavy gears so you can just use a granny chainring without worrying about range or your front mech getting clogged
How much top speed do you lose going from 2x to 1x?
very little!
@@BOB-su2kd Just bought a new bike, it's 2X!
Champlin Rapid
In the end , I will never give up my 53/11 high gear.....so I'll choose 2× in anything but a mountain bike, or a casual commuter
@@DejanOfRadic im impress you run that gear all the time.
It all depends how many bike can you fit at home 😂
I still prefer my bikes with a Triple, and my piano with 88s 😊
2x end of story

Love 1x on my gravel bike. I'm definitely 1x on my mountain bike but if I were forced to have 2x on one of them, it would be my mountain bike

Wrong !
