SRAM X1 Type 2.1 11SP Rear Derailleur

SRAM X1 11-Speed X-Horizon Rear Derailleur

With the introduction of X1, SRAM brings their popular 1x11 speed drivetrain to the masses. X1 uses much of the same technology of X01 with more price-conscious material choices. In the case of the SRAM X1 X-Horizon Rear Derailleur the only main difference is an alloy cage instead of carbon. Adding all of 4 grams to the design and saving you more of that hard earned cash. Every detail of the 11-speed X1 X-HORIZON™ rear derailleur is engineered for smooth, reliable shifting action—from the larger upper pulley offset to the 12-tooth X-SYNC™ pulley wheels. By eliminating unwanted chain movement, X-HORIZON™ shifts faster, puts an end to ghost shifting and reduces shift force and chain slap. And with CAGE LOCK™ technology, wheel removal and installation are easier than ever. SRAM X1, X01, and XX1 are all cross compatible with each other, allowing you combine parts from each if desired.

Features:

  • Large upper pulley offset automatically adjusts chain gap
  • X-HORIZON™ design reduces shift force, ghost shifting and chain slap
  • 12-tooth X-SYNC™ pulley wheels
  • Aluminum Cage
  • Sealed cartridge bearings
  • 11-speed
  • Compatibility: X-ACTUATION
  • Pivot Design: Horizontal Parallelogram design
  • Claimed weight: 256g

Quicker and more solid engagement.
I have rode xt 11 speed , xtr, x9, and x1 drive train. That being said the x1 group set was the quickest shifting and had the most positive engagement.

In terms of shifting it is all in the feel wanted weather you pick sram or shimano.

Sram is a more race like feel were the next gear is press , bang, boom its there and your keeping your cadence without the lag. But you get the solid engagement knock feel like that of a race car transmission.

Shimano is slower but smoother feel more like that of a luxury car. Its press, quarter pedal stroke, it slides, its there.

What are you looking for a want to be fast and aggresive race car type of rider that wants to bang gears coming into the next section and slay the track leaving dust behind or are you looking to drive that lexus down the highway riding smooth and comfortable as you take the steady cadence and long miles.

Full featured 11 speed shifting
I have been looking at going 11spd on my MTB for some time, and when I finally pulled the trigger, indications were that this X1 derailleur was in the same feature and reliability category as the higher end derailleurs, although not as light. I decided that made this the sweet point in price/performance ratios, and I haven't been disappointed. To a certain extent, setup of this derailleur was tricky, it's very sensitive to B-screw settings, but once that was tweaked it came together well, and has continued to shift flawlessly.

PROS: Easy To Install, Attractive Design, Durable

CONS: Tricky Setup

Accurate, smooth, and rugged
This is my second one, and I'd buy it again. Smooth, accurate, and rugged - it takes a beating.

near XX1 performance at reasonable price
i have XX1 on another bike and concur with the reviews that say that the performance of X1 is pretty much same. you get forged parts here vs cast with GX so durability should be better. X1 is the price performance sweet spot level IMO.

PROS: Great Shifting

BEST USES: Racing, Mountain Biking

SRAM X1 good buy
Love it so far. Just make sure to read install directions and guide the cable correctly right before its clamping location.

Went for forged over cast aluminum.
It's a good derailleur with forged parts as opposed to the cast parts in the GX line.

Only complaint is the plastic jockey wheels, but that's just my preference.
