The K1SL is KMC's lightweight step up from the K1, built with all-hollow construction for BMX and singlespeed riders who want to save weight without giving up strength.

  • All-hollow pin and plate construction for reduced weight over the standard K1
  • 112 links
  • Available in Narrow (3/32") and Wide (1/8") widths — check your freewheel/cog before ordering
  • Reinforced tensile strength for BMX and singlespeed use

Positioned above the standard K1 in KMC's single-speed range, aimed at riders who want a lighter chain on their BMX or singlespeed build without compromising on durability.

Fits singlespeed, fixed-gear and BMX drivetrains. Confirm whether your bike needs the Narrow (3/32") or Wide (1/8") width before ordering — the two are not interchangeable.

KMC chains are covered against manufacturing defects. If a chain fails from a defect in materials or workmanship, return it to Tune Cycles with your proof of purchase and we'll manage the claim with KMC on your behalf — no need to contact the distributor yourself. This is in addition to your rights under Australian Consumer Law, which apply regardless of any manufacturer's warranty.
