The 5 Best Bike drivetrain kits (2023 reviews)

The kit is a must have accessory for your daily purpose. It requires chain rings with 104 BCD measurement. It is great for mountain biking because they are not so great for the high impact and extreme cadence of bmx racing. The arm bolts to the crank thru-axle with two allen bolts so you don't need any crazy tools to install it. The cap doesn't serve much purpose besides sealing off the thru hole from mud so the plastic is fine.

The new set is very noticeably lighter and feels smooth. The female part of these bolts should be at least 2-3 mm longer to lock chainring against the crank. It will fit chainrings which are 104BCD which are fairly standard.

Why We Like This:

Great kit option to upgrade from a regular set
Very high quality crank arms and bb
Easy install with the correct tools
More bb creaking and no more noisy front derailleur
