All about SRAM XX1 X01 AXS GX NX SX 2021 transmissions
SRAM XX1 AXS: amzn.to/371zHUp
SRAM XO1 AXS: amzn.to/2SRF28f
About 3 years ago SRAM launched the Eagle group, the first single chainring gearbox with 12-speed sprocket.
It was a huge success right from the start.
The new Eagle technology has effectively heralded the death of the front derailleur.
Eagle's story began with the high-end X01 and XX1 groupsets, followed soon after by the cheaper GX and NX groupsets.
To these groups, last year at Eurobike, SRAM presented the famous electronic AXS.
In this video, in addition to highlighting the differences between the various groups, we will also try to clarify which transmission is best suited to the different types of mountain bikes.
SRAM transmission groups have different costs, dictated by the materials used, weight and technology.
Let's find out the various weights.
The heaviest drivetrain is the SRAM SX Eagle, at 2328g
This is followed by the NX Eagle model, with 2043g
With the weight of 1767g the GX Eagle drops below 2kg
In fourth place we find the first SRAM X01 Eagle AXS electronic transmission with 1547g
Closely followed by the traditional X01 Eagle with 1509g
In second place we find the second electronic transmission, the XX1 Eagle AXS weighing 1495g
And in first place we find the XX1 Eagle with 1448 grams
The Eagle X01 and XX1 were launched by SRAM in 2016 and still today are the two main cutting-edge groupsets.
It is a 1 x 12-speed gearbox, light, technically bright, wear-resistant and with an attractive look.
Of these two groups there is also the electronic version, with a wonderfully ordered look, without cables or guides to the frame.
The XX1 Eagle group and the AXS version have been designed for Cross Country, Marathon use
While the X01 group and the AXS electronic version, being a little more robust, are better suited for Trail, AM, Enduro use
In June 2020 the two groups were slightly modified, the rear derailleur was revised to better match the new 10-52 tooth cassette.
SRAM GX Eagle
As for the GX drivetrain, this is mainly mounted on mid-range MTBs costing € 2000-3000
The GX transmission offers the same range of gears and technology as the XX1 and X01, but is significantly cheaper as different materials are used which add to its weight.
For example, the gear lever is made of aluminum as are the materials of the cassette.
The GX Eagle weighs around 250g more than the X01 Eagle, but costs less than half.
2021 Update: From summer 2020 the GX Eagle is available in a visually modified version and a tailor-made rear derailleur for the new 10-52 tooth cassette. A carbon crank is also available to expand the range.
NX Eagle
The NX Eagle drivetrain has a somewhat heavy cassette and is 11-speed, so slightly less bandwidth than the 10-50 models of the more expensive Eagle groups.
The advantage of this cassette is that it fits the standard freewheel (Shimano), so it does not need the special Sram XD body and is a pretty sturdy gearbox.
The shift lever is made of plastic
The price is low and this makes this drivetrain suitable for most entry level mountain bikes
SX Eagle
And lastly we find the SX Eagle transmission, introduced by Sram in 2019.
This is also a group that is mounted on entry-level bikes, but compared to the NX it has the advantage of mounting a 12-speed cassette. The weight is a nice 2328g
Since June 2020, SRAM has introduced a new 12-speed 10-52 (10, 12, 14, 16, 18, 21, 24, 28, 32, 36, 42, 52) cassette and has overhauled (aesthetically only) the GX, X01 AXS and XX1 AXS rear derailleurs which can now work with both the new 10-52 cassette and the old 10-50 cassette
The cassette is now offered in 3 different colors:
• gold,
• rainbow
• and the new copper color.
• For X01 there is also the black cassette
For 2021 SRAM has introduced the "Eagle Ecostithema Expansion" concept, which means that most of the Eagle solutions introduced and that SRAM will introduce, may be compatible with other components
Cassette 10-52 for example, could be mounted on transmissions:
XX1 (2021) 457 €
XX1 ASX (2020) 457 €
X01 (2021) 391 €
X01 AXS (2020) 391 €
GX (2021) 220 €
