Where can I buy a new magnet?

International customers: Contact your local SRAM Dealer.
I have a broken battery lid. How do I get a replacement?
USA and Canada: Use the Contact form, and be sure to include the following:
Can I swap between SRAM GXP and BB30 cranksets?
Yes. You must return the entire power meter to the factory in Spearfish. We will perform the changeover, install a standard (non-power meter) spider on your original crank arms and return both to you. Your power meter will be inspected and calibrated. You will be charged for the new crank arms and must pay for shipping both ways. Contact our customer service team to get started.
What options do you have for BBright?
Quarq and SRAM BB30 power meters work with BBright frames. You must remove the pre-load adjuster and small spacer from the spindle, and reassemble the crank with the wave washer against the non-drive arm, and the large 13mm spacer on the drive side. The wave washer is included with the PressFit30 bearing assembly kit. Contact our customer service team for an instruction sheet.
Can I install a power meter spider on my SRAM crankset?
No. We cannot fit power meters to existing cranksets.
I have a Shimano crank. What are my options?
Quarq's ELSA 10R and RIKEN 10R power meters use 10-speed chainrings and can be fitted with alternative chainrings of your choice.
I have an 11-speed drivetrain. What are my options?
We have customers successfully using the following chainrings on Quarq power meters with 11-speed drivetrains:
