Yet another 11s offering from SRAM, this one is an entry level grouppo for the masses (with a lot of mass, of course)
After churning out their GX range, SRAM released the NX groupset which is cheaper than GX. While GX is with an option of running either 1x11, 2x11 or 2x10, they set this one out as a 1x11 offering. However, unlike the previous 11s from SRAM, NX does not require the XD Drive freewheel body. Hence it is without the 10T in the cassette.
The cassette in NX range is PG-1130, with 11-42T range and more than half a kilogram weight (538g to be exact). In front, the chainring offered are 30, 32, 34,36 & 38T. The crank is Boost 148 compatible , and also available for fatbike (4") as well as a plethora of different BB standards. This may be a cheaper option for getting 1x11 onto the fatbike, but you do have to consider the weight penalty to pair with the already hefty bike.
MTBR has put up a X1/GX/NX comparison chart - weight and price (USD). Check it out.
