The KMC chainring with Aurora PVD coating combines reliable chain retention with a standout finish for riders who want their drivetrain to perform as well as it looks.

Machined from CNC-milled AL7075 T6 aluminium and built for 104 BCD 4-arm spider setups, it features the same narrow-wide tooth profile found across KMC's chainring range, with alternating tooth widths that interact precisely with the chain to significantly reduce the risk of dropping on rough or technical terrain.

What sets this version apart is the iridescent Aurora PVD surface treatment, which goes beyond aesthetics to deliver genuine performance benefits, reducing friction, improving scratch resistance and corrosion protection, and extending the overall service life of the ring. Optimised to work seamlessly with KMC chains, it supports 9 to 12-speed drivetrains and any chain measuring 1/2" x 11/128", with the sole exception of SRAM T-Type. A chainring that pairs eye-catching looks with genuine durability gains.

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.
