You're going to have painfully large gaps between ratios. That, and there is no way on this earth I'm putting a 40t dinnerplate on the back. Might as well leave on the spoke protector.

I run an 11-32 on my do it all bike, and the gaps aren't that bad compared to the 11-28I have on my other bikes. Don't forget that we're at 11 speeds now!

11-28 will be used on race wheels. I think those ratios are fine.

for spring (although it hurts to leave Campy...) I really can't see a reason for not doing it, especially for crit racing.

If no one has said it yet, I'm saying now. Give it two years and it'll be as common as 2x for amateur racing.


Why? It's heavier than 2 x 11 and more chain friction. I just don't see the point for a road bike.

For gravel and cross no issue.

I don't see that. You're missing half a shifter, a cable, an outer, a derailleur, a chainring and maybe a drop catcher . That more than makes up for a few larger cogs out back. Would be interesting to see the two side-by-side though.

If you have Strava, I did a mid-speed group ride yesterday on a 1x setup: Oval 40t front chainring, 11-28 11sp cassette, 30mm tires: https://www.strava.com/activities/439543479/analysis

Never ran out of gears, but would have preferred the 11-32 cassette on the one short 15% climb we had.

Had to briefly spin 110rpm for top speed. I'm ok up to 125rpm for a short duration.

In the flat "Armstrong Style"-Segment I was pulling the group at 300+Watts (the rider right behind me was getting 240-250W from his P2Max) with a slight rear wind, and I was on the 13/14/15 cogs (3rd/4th/5th fastest gears).

Gearing: http://ritzelrechner.de/?GR=DERS&KB=40& ... 2.6&UN=KMH

My conclusion: Don't overgear! And maybe have 2 chainrings (44 & 50) and swap depending on the course.

SRAM Force 1
Rear Derailleur - Medium 261 grams
Cassette 11-36 366 grams
PC1170 256 grams
Force 1 Crankset - 50T 679 grams

Total 1,562 grams


Force 22
Rear Derailleur - Short 178 garms
Front Derailleur 79 grams
Cassette 11-25 231 grams
PC1170 256 grams
Force 22 Crankset - 53/39 697 grams

Total 1,441 grams

Force 22 lighter by up to 121 grams. Running an 11-28 on the Force 22 would bring the gap back a bit as would a chain catcher at 10 grams and front derailleur cable but still a clear win to Force 22 on weight and 11 extra gears.

As someone who lives right next to the beach with ZERO hills near me, I like the idea of this setup though as of right now I am running a 42/54 paired to a 12/25.

If I had a friend that was just starting in cycling I would suggest this groupset as it easier to understand and less to work on.

121g for the ease of one ring? Fine with me, you can make that up elsewhere no issues, or ignore it; hardly the difference between 1st and 2nd place.

If riders have difficulty with front shifting then this (1 x 11) is a good groupset for them.

Probably not, normally it's the rider that makes the difference between first and second place in a crit. I'm not trying to talk you out of it simply responding to you disputing that the 1 x 11 was heavier.

Sure, I guess it's relevant to this forum.

I have just made my winter bike with a Rotor QX1 48 front ring and a standard Shimano RD. This paired with a 11-28 cassette in the back. I love it!

FYI, 48/11 is exactly the same gear as 53/12.

I don't see you adding weight for cables / housing of front der on the 2x11 setup?

Where are you getting the weight for the Force Cranks 2x11?

Fairwheel did a crank test and the Force 22 cranks are quite a bit heavier than you show

Sram Force22 (2014) 782.3

Competitive cyclist says 715g Actual weight for 2015 version?

So you get to save 120 grams in a place where it gives you the least benefit. Sounds like a great idea.

The benefit is a much better looking, easier to maintain bike.
