SRAM Road AXS | How to: Install a Spider-based Power Meter

A one-piece design means this 2x power meter is the lightest, stiffest, and most accurate upgrade for your Force drivetrain. The integrated power meter and chainring combo includes our ultimate Quarq D-Zero technology for right and left leg power readings, accurate to +/-1.5 percent, and our consistent 13-tooth gap on the rings for fast and reliable shifting.

1. Use an 8 mm Hex wrench to loosen the drive side crank arm counterclockwise.
2. Shift the front derailleur inboard to the smallest chainring and remove the chain from the chainring.
3. Remove the crank from the crank spindle.
4. Flip the crank to reveal eight T20 bolts.
5. Use a T20 Torx wrench. Turn counterclockwise and remove all eight T20 bolts.
6. Place the spider-based power meter on a soft surface.
7. Pull the plastic cap off, unscrew the metal cap, and remove the paper insert.
8. Screw the metal cap back on, install the plastic cap, and remove the install sticker.
9. Install spider-based power meter into the crank arm, ensuring the black tab aligns with the crank arm.
10. Loosely install the T20 bolts, turning clockwise.
11. Use a T20 torque wrench to tighten to 4N-m following a star-shaped torque pattern.
12. Put the spider-based power meter crankset on the crank spindle.
13. Tighten clockwise with 8 mm Hex wrench.
14. Put the chain back on the chainring.
15. Use an 8 mm torque wrench and tighten clockwise to 54N-m.

Genius video, but I've come to expect nothing less from SRAM! Simple and clear and instructions on screen rather than narrated. 👍

[jorgechang]

you made it seem so easily to torque to 54 Nm :D and even easier to remove the crank..

Can you share the product number (and probably link to product page for ordering) for the powermeter which is used in the video to be installed on the new FORCE AXS?

[JasonLatorre]

2:29 Grease it up good, 0:16 or in the future you’ll need to add a flag pole for leverage.

I like the tools you used in the video. Who makes them?

[CatManDoSocial]

I want my power meter to be integrated into my chainrings so I have to replace it if my chainrings ever get damaged, wear out, or I just want to change the number of teeth. Said no one, ever. Why do you all think this is a good idea?

[alekschify]

Cool video but I still have an open question: what exactly is the difference between the SRAM Force Dub 35x48t and the SRAM Force AXS Dub 35x48t crank?

[jesperlaursen]

SO just to be sure, when my chainring is up for replacement, i need to buy a new chainring/powermeter?

[RidingBikes]

Might be a dumb question, but could I install the crank arm power meter instead of the spider based one if I wanted (can you use both)?

[kevinproost]

will this fit also the rival Etap 12speed?
and if not is there a sider compatible with rival?
or is the force crank compatible to be exchanged without any fuzz with the rival ?

Hi, I want to ask a question. I have a Sram Rival XPLR 1x groupset. Can I install a Sram Force AXS spider based power meter? My local store says it works, but I'm not sure.

[GroomsJk]

I recently purchased the new Cannondale EVO 1 equipped with the new SRAM Force group w/o a power meter. Is this the only part I need to buy to convert my bike to get L/R power measurements? Thanks - J

[patrickrenschler]

Do you have a video showing how the "SRAM threaded chainring removal tool" is supposed to be used for red xplr power meter cranks?

[TonySalazarTotalFit]

Is it compatible with the new axs Rival? If so, how could it be ordered in usa?

[waepekk]

Is the force d1 power meter compatible with the d2 crank?

[blinzi]

no initial setup needed anymore in the app?

[wksoon]

what is the difference between force and red 2x power meter chainring?
Are the force chainring heavier ? is yes by how much?

[matthewnapier]

Will this work with the last generation of Force?

[karlosarmiento]

Can I go from force d1 48/35 to the new force d2 50/37 without changing the chain?

[GuilBarros]

What brand are the tools in this video?
