How to Choose a Single Speed Chain
Single speed bikes have no derailleur, so the chain only needs to fit one front and one rear sprocket. The key choice is the chain width, which must match your sprockets.
3/32" or 1/8"?
Narrow 3/32" chains suit single speed bikes and fixies with 3/32" sprockets, such as many converted road frames. Wide 1/8" chains suit BMX, cruisers, beach bikes, kids bikes and track bikes. Check the sprocket or your old chain if you are unsure.
Half Link Chains
On a single speed bike, getting the chain tension right can be tricky with full links. The KMC HL1 half link chains let you adjust the length in smaller steps, making it much easier to get a perfect fit, especially on frames with short dropouts.
Tough and Colourful
The KMC K1 uses patented K-shaped plates to withstand high impacts, ideal for fixies and dirt jump bikes. The KMC S1 is a quiet, budget-friendly 1/8" chain in Brown, Silver or Red, and the HL1 comes in a gold finish.
Single Speed Chain FAQs
How do I know if I need a 3/32" or 1/8" chain?
Match the chain to your sprockets. BMX, cruisers and track bikes usually use 1/8". Single speed conversions and many fixies use 3/32".
What is a half link chain?
A chain where every link is a half link, so you can adjust the length in half link steps for perfect chain tension.
Can I use a derailleur chain on a single speed?
A 3/32" derailleur chain can work on 3/32" sprockets, but a dedicated single speed chain is stronger and better suited.
How do I join a single speed chain?
Use a single speed connecting link, a chain tool, or the connecting bullet pin supplied with the KMC HL1.
