WOLF TOOTH chainring 104x38 BCD Drop-Stop B

Product description

The Wolf Tooth 104 BCD (38 teeth) chainring is based on the most widely used bolt spacing for both double and triple cranks and is an iconic product that started the Wolf Tooth Components brand. It uses the patented Drop-Stop® tooth profile, which is one of the most durable and reliable wide/narrow tooth systems on the market.

The wide side of the tooth ensures maximum contact area on the drive side, which effectively distributes the load and extends the chainring's life. The narrow side of the tooth, on the other hand, creates enough space for self-cleaning from mud and dirt, thus reducing friction and reliably preventing the chain from falling off.

Key features

• Size 38 teeth: A great choice for fast cross-country trails, marathons and e-bikes.

• Drop-Stop® Technology: Patented wide-and-narrow tooth profile prevents chain drop on single-plate (1x) drivetrains without the need for a guide.

• E-bike ready: The design fully meets the strength requirements of e-bike drives.

• Wide Compatibility: Suitable for any crankset and power meters with a standard 104 BCD pitch (including Quarq power meters).

Compatibility and assembly

• Cranks: Fits all cranks with 104 BCD spacing (4 bolts).

• Chainring Bolts: This 38T version uses standard 1x 6mm bolts. (If you plan to use a bashring, you will need 8mm bolts.)

• Drivetrains: Compatible with 1×9, 1×10, 1×11 and 1×12 systems.

  • Tip: When used with a 9-speed drivetrain, the manufacturer recommends using a 10-speed chain, which fits better on the teeth and further increases safety against falling off.
