What's a Front Derailleur?

SRAM's Force 1x was quite the revelation for 'cross. While many riders ran DIY 1x setups for years, this was the first truly dedicated 1x group. A clutch rear derailleur and narrow/wide chainrings all but eliminated dropped chains and redundant gears letting the rider focus on the race and not always worry if they are in the right gear. The notion of running 1x has bled over to other disciplines now there is enough range for all of your road and gravel exploits with the before mentioned benefits. Install the Force 1 Type 3.0 Rear Derailleur on your next 1x build and take advantage of the consistent accurate shifting this latest update delivers.

Keeping the chain on the chainrings over the roughest terrain is afforded by the clutch derailleur. SRAM developed its Roller Bearing Clutch technology to aid in chain retention and have made incremental updates as time goes by. This latest version, 3.0, features a smoother torque curve for quieter and more consistent operation and feel. You'll experience a quieter ride free of chain slap and with SRAM's 1x specific X-Horizon technology, shifts require less effort at the lever, with better accuracy, and without fuss under loads. SRAM's Exact Actuation technology means the same amount of cable pull is needed to initiate a shift anywhere on the cassette. That means the same lever response is required shifting from the 11 to the 12 as the 36 to 42.

The SRAM Force 1 Type 3.0 Rear Derailleur has an ingenious Cage Lock function that allows you to place the cage in a position that makes removing and installing the rear wheel easy. Push the cage forward and push the button in to lock it into place. Once the wheel is installed, push the cage forward again and you are ready for action.

  • A 1x specific rear derailleur for CX, gravel, and road
  • Compatible with 10 and 11-speed Exact Actuation Shifters
  • Exact Actuation allows for fast and accurate shifts
  • Cage length versions available for 11-26 through 10-42 cassettes

Rock solid

  • Familiarity: I've put it through the wringer

This is a workhorse of a derailleur. Tough, reliable, smooth in operation and needs adjustment only infrequently. It’s a shame SRAM isn’t offering a 12 speed mechanical version.

Great 1X Derailleur By Design

  • Familiarity: I've put it through the wringer

Earlier this year, about 2000 miles ago, I changed my makeshift 1X (Shimano Ultegra) to real 1X (SRAM Force 1). Many people say Shimano works better, but I trusted my LBS and went to SRAM. They were so right. Shifts are more solid, positive, and accurate. The derailleur stays in adjustment better too. Now that I've lived with the derailleur for a while I can tell you WHY it works better.

#1 SRAM moves 1mm for every 1mm cable pull, but Shimano moves 2mm for every 1mm pull. SRAM can be adjusted more precisely and temperature extremes have less effect.

#2 the SRAM cable attachment point is a large arc shape that keeps cable-to-pivot distance constant through full gear range.

#3 Shimano feeds each shift in 2 steps - half on the push and the other half when returning the lever to neutral. SRAM makes its entire pull in a single large step as the lever is returning, which is a more reliable and positive action.

#4 SRAM pulleys are narrow/wide type, guiding the chain more accurately.

Negatives? With double tap you can accidentally shift the wrong direction, but that is very rare after the first couple learning curve rides. When riding into a very steep hill at night (can't see the cassette) it is sometimes difficult to tell if you are in lowest gear or next-to-lowest.

Winter rider note: Double tap levers are much easier to use with gloves or mittens than Shimano.

Bottom line is that I recommend SRAM derailleurs.

I agree with this assessment. I used shimano for years too and used to tune things up every couple months. Now I've been riding a Sram Force 1x setup and (no front derailleur makes a difference I'm sure) no adjustments needed, over a year later!

Works just fine

  • Familiarity: I've put it through the wringer

I'm posting to make a note that the Sram website says the medium cage can take a 11-36 cassette (rather than max 11-32 as stated here). I've run it that way without a problem.

Hello Randy,

Thank you very much for reaching out and clarifying this detail for us! I'll be sure to pass it along to our copy team and get the description remedied right away, but if you need anything in the meantime, please don't hesitate to reach out at!

1x range.

I've owned previous SRAM Force CX1 derailleurs in the past and stepping up to the long cage so I can run an 11-42t cassette for more range most of the year and still run 11-32t for CX. Looking forward to seeing if the Type 3.0 is stronger or offers any additional chain retention (not like I had an issue with the older clutches).
