The 34T bike crankset is designed for single speed bikes. Made from aluminium alloy, it is lightweight, weighing just 710 grams. If your current crankset is steel, this upgrade can significantly reduce your bike’s weight. Additionally, you can replace the cranks with smaller sprockets to increase your bike’s top speed. This crankset is ideal for upgrading or replacing a multi-speed crank with a single speed option.

170mm bike crank


If your derailleur has trouble shifting gears, this 170mm bike crankset is a cost-effective alternative to replacing the entire system. Replace your multi-gear crankset with this single speed crankset, and remove the front derailleur and gear shifter stick. This change simplifies gear shifting and makes it more reliable, while also reducing the weight of your bicycle.

When replacing a multi-gear crankset, we recommend testing your current gears on the multi-gear setup first. This helps determine the ideal number of teeth for your single sprocket set. For more bike cranksets, check our other listings.
