Electric bike chain Black Friday: discounted prices
During Black Friday, this page brings together bike chains for city bikes and electric bikes: E-Bike models with 8 to 12 speeds, chains for hubs with internal gears or single speed, and some road and mountain bike chains, with reduced prices on many of them throughout November. An electric bike chain is primarily chosen based on the number of speeds of the drivetrain; it is also designed to handle the torque from the motor.
E-Bike Chain: What’s Different?
An E-Bike chain has the same width as standard chains of the same number of speeds: a 9-speed E-Bike chain will fit a 9-speed cassette without any other adjustments. What’s different is its construction, which is reinforced to handle the motor’s torque and gear shifts under load: treated axes, tougher plates, and corrosion-resistant finish. Shimano offers it in CN-E6070 for 9 speeds, CN-E6090 for 10 speeds, and CN-E8000 for 11 speeds. However, on a daily-riding electric bike, it wears out faster than on a standard bike: check it more frequently.
Hub with Integrated Gears or Single Speed: Wide or Narrow Chain
Without a derailleur, the chain doesn’t need to shift from one cog to another: it can be wider and more robust. Two widths coexist, 1/2 x 1/8 inch and 1/2 x 3/32, and the correct one depends on the cog and chainring in place. The CN-NX10 from Shimano, in 1/8, is designed for Nexus hubs with 3, 7, or 8 speeds; KMC offers its Z1eHX in narrow or wide versions for electric bikes with integrated hubs. If in doubt, check the bike’s manual or the marking on the cog for clarity.
Discounted Chains: Four Points Before the Strikethrough Price
To read a discount on a chain, it must be for an exactly identical reference: before comparing the strikethrough price to the displayed price, check these four points.
- Length: the same model can be sold from 110 to 138 links. Count those of the old chain and take at least as many.
- Packaging: several references are sold individually or in packs of 25, a workshop format.
- Closure: quick-connect link provided or closure axle, reusable or not depending on the model.
- Finish: nickel-plated, rust-treated like KMC's EPT, or stainless steel for some parts.
Other Parts and Pages of the Operation
The listing also includes road and MTB chains for 11 and 12 speeds, including models with their own standards like Sram T-Type or Flattop: they have their place in road chains in Black Friday, MTB chains in Black Friday, and the chains of the operation, all practical items gathered. A new chain runs poorly on worn teeth: check the city cassettes in Black Friday and the chainrings for motor and crankset. For the rest of the year, urban cassettes and chains detail length and maintenance, and the urban transmission in Black Friday groups all the parts. After the operation, check the clearance sale and the new arrivals.
What Chain Brands Are Available During the Operation?
Shimano offers, alongside its E-Bike chains, the CN-NX10, a 1/2 x 1/8 chain with 114 links for Nexus hubs, and the CN-LG500 from the Cues transmissions.
KMC features the Z1eHX, a chain for electric bikes with integrated hubs or single-speed, available in narrow or wide versions and EPT rust treatment.
Sunrace dedicates its CNM8E and CNM9E chains, for 8 and 9 speeds and 138 links, to electric bikes; the CNM9E comes with chromed axles.
Wippermann, a German chain manufacturer, equips the Connex 10sE with stainless steel inner links and rollers, and delivers it with the Connex Link, a connector that closes and reopens manually.
Frequently Asked Questions
Are the chains part of the operation?
Yes, those on this page. The term Black Friday refers to the Friday after Thanksgiving, but at Vélo-Store, its discounts on city and electric bike chains cover the whole month of November.
What chain for a Shimano Cues transmission?
An 11-speed chain, LinkGlide like the CN-LG500 or Hyperglide, regardless of whether the Cues cassette has 9, 10, or 11 cogs. That’s one of the features of this range.
How long does an electric bike chain last?
There’s no fixed mileage: assistance, terrain, rain, and maintenance all affect wear. The only reliable indicator is the wear indicator, which measures the chain’s elongation.
How to clean and grease an electric bike chain?
First, remove the battery, as recommended by motor manuals. Wipe the chain with a cloth, degrease it if it is dirty, let it dry, then put a drop of lubricant on each roller and wipe off the excess.
How to assess an offer on a chain?
By equal reference: same number of speeds, same length, same packaging, and same closure. A chain sold in packs of 25 can only be compared to another workshop lot.
