The KMC e-bike chainring is built specifically for the demands of electric drivetrains, where consistent power transfer and durability matter even more than on a standard setup.

Constructed from quality steel and designed for 104 BCD 4-arm spider cranksets, it features the same narrow-wide tooth profile that defines KMC's chainring range, with alternating tooth widths providing secure chain retention even under the increased torque and load that motor assistance puts through the drivetrain.

The steel construction is specifically chosen here over aluminium to handle that additional stress reliably over the long term, while also delivering maximum efficiency that helps preserve battery life rather than wasting power through unnecessary drivetrain friction.

Perfectly matched to KMC chains, it covers e1, e8, e9, e10, e11 and e12 speed configurations, though it is not compatible with 12 or 13-speed flattop chains. A dependable, purpose-built upgrade for any e-bike rider who wants their drivetrain to keep pace with their motor.

Stronglight 130 BCD Black Chainring Dural 5083 Alloy

Very tough and comfortable

I had Abus bordo but I need more protection for my new e-bike. So folding lock is a very good option to your powerful u-lock (eg. NY crypto or Litelok x1-x3. So thanks a lot for the good discount and I will buy again in this shop !!!

Foldylock 110 cm Elite Folding Cycle Lock

Fast delivery and good quality

My chain cleaner arrived very quickly. The item is very robust and seems very well put together and better than some of the cheaper plastic chain cleaners that I’ve had in the past which just break very easily. This one is made in Italy and so that makes a welcome change. It is a good quality product. I’m sure will last me a long time..

FSA K-Wing AGX Carbon Compact Drop Road Bar

Seatylock 21cm

Not too heavy, big enough to go over a ebike frame, spare keys. Unsprung design, no holder - but reassuringly well made, would buy again. Best security rating too keeps the insurers happy. Sprocket & Gear sent it out fast and well packaged all for the best price I could find. Highly recommended.
