Built to handle the high torque and demanding conditions of e-bike riding, the Burgtec 104mm BCD Inside Fit Steel Thick/Thin Chainring delivers uncompromising chain retention and exceptional durability. Precision machined from steel and finished in signature Burgtec Black, this 32-tooth chainring features a narrow-wide tooth profile that grips the chain securely, virtually eliminating chain drops even on rough terrain or under heavy motor assistance.

Features

• Steel construction — outstanding wear resistance and strength, ideal for e-bike applications.
• Thick/Thin (narrow-wide) tooth profile — prevents chain derailment without a chain guide.
• 32-tooth count — balanced gearing for climbing and e-bike cadence.
• 104mm bolt circle diameter (BCD) — a widely used standard for e-bike cranksets.
• Inside fit mounting — sits inboard of the spider tabs; suited to most non-Shimano motors (always confirm spider orientation).
• Threaded bolt holes (8mm x 0.75mm x 8mm) — compatible 8mm-long chainring bolts are included.
• Durable black finish — matches Burgtec’s iconic colourway and resists corrosion.

Why choose the Burgtec eBike Steel Chainring?

E-bike motors place massive stress on the drivetrain. This steel chainring is engineered to withstand that abuse, offering far longer life than aluminium alternatives while keeping the chain firmly in place. The inside-fit design ensures a neat chainline on most e-bike spider configurations. With bolts supplied and Burgtec’s renowned build quality, it’s a straightforward, reliable upgrade for your e-bike.
