Quarq DZero Power Meter Options

BCD: 110 or 130

BCD is bolt chain diameter. This is a measurement of the size of the crank spider. Most 50/34T and 52/36T rings use a 110 BCD, whereas 53/39T use a 130 BCD. If you are not sure what your BCD is, please contact us so we can help.

Crank arms: 165 mm | 167.5 mm | 170 mm | 172.5 mm | 175 mm

You can purchase the power meter with or without crank arms. Available crank arms are:

DZero DUB – These are the crank arms that are pictured above and will ship with the power meter unless otherwise specified (they require a SRAM DUB bottom bracket). Unless you need GXP or higher-end SRAM RED crank arms, these are the ones we recommend.

Force GXP – If would like to use a GXP bottom bracket on your bike (Trek BB90 for example), the SRAM Force GXP Crank Arms will work perfectly. Please select ‘No crank arms’ on this page and then add Force GXP Crank Arms to your shopping cart.

RED DUB or GXP – If you are looking for the best SRAM has to offer, the SRAM RED Crank Arms are it (available in both DUB and GXP). The RED cranks are lighter (by about 140 grams) and stiffer than the DZero and Force arms. If you would like to order the power meter with SRAM RED cranks, please select ‘No crank arms’ on this page and then add the SRAM RED Crank Arms to your shopping cart.

Chainrings: 50/34 (110 BCD) | 52/36 (110 BCD) | 53/39 (130 BCD)

You can purchase the power meter with or without chainrings.
