????♂️ What it is
The SRAM Thread Mount Chainrings 50/37T are:
- the front gears on your bike
- mounted directly to the crank spider using SRAM’s Thread Mount system
???? This is what determines your gearing (how hard/easy it is to pedal at speed or on climbs)
⚙️ Key specs explained
⚙️ 50/37T gearing
-
50T (big ring) → speed, flats, descents
-
37T (small ring) → climbing, endurance
???? Compared to traditional setups:
- slightly more compact than 52/36
- good balance for:
- climbing
- long rides
- mixed terrain
???? Thread Mount interface
- Screws directly onto the spider (no bolts)
???? Benefits:
- lighter
- stiffer
- cleaner design
???? But:
- requires a special removal tool
⛓️ 12-speed compatible (Flattop chain)
- Designed for modern SRAM AXS drivetrains
???? Must use:
???? Aluminum construction
- Durable and precise shifting
???? Slightly heavier than carbon rings, but:
- more robust
- better wear resistance
???? Important compatibility insight (this matters)
There’s a big distinction:
-
RED XPLR AXS power meter → 1x only
-
These chainrings (50/37) → 2x setup
???? So:
❗ These will NOT work with the XPLR 1x power meter you looked at earlier
If you want:
- 1x → single chainring (XPLR)
- 2x → these chainrings + different spider
????♂️ How it feels on the bike
With 50/37 gearing:
- ???? good top-end speed
- ⛰️ easier climbing than race gearing
- ???? smoother cadence control
???? Ideal for:
- endurance rides
- rolling terrain
- mixed conditions
???? How it fits your setup
With your other components:
-
Crank arms (SRAM Force) → structure
-
Chainrings (this) → gearing
-
Power meter → data
???? Together = your drivetrain system
⚠️ Things to consider
- ❗ Requires SRAM Thread Mount tool
- ❗ Must match your drivetrain (AXS 12-speed)
- ❗ Not compatible with XPLR 1x setup
???? Bottom line
The SRAM Thread Mount 50/37T chainrings are:
- ⚙️ versatile 2x gearing option
- ???? great for mixed terrain and endurance
- ???? stiff and efficient with thread-mount design
- ⚠️ only for 2x AXS setups
