Bike Crank Set 36T with 170 mm Square Taper Arms and 104 BCD Narrow-Wide Chainring Black

36T Crankset for routes that mix climbs and open stretches

A ride can start with traffic lights, climb through the suburbs and finish on an open cycleway. This 36T vike crank set suits that mix. It pairs 170 mm square-taper crank arms with a narrow-wide chainring for a compatible single-ring drivetrain.

Choose 36T if your current 44T ring makes starts and climbs harder than you’d like. With the same cassette, the smaller ring lowers every gear. It also gives you taller gearing than a 32T ring for open stretches of road or gravel.

Key Features

• The 36-tooth front ring suits rides with a mix of starts, climbs and faster sections.
• Alternating narrow and wide teeth help keep a compatible chain engaged as you ride over uneven ground.
• The 170 mm arms keep the same pedal circle if you already ride cranks of that length.
• The four-bolt 104 mm BCD mount lets you replace the chainring separately when it wears.

Benefits of Riding with a 36T Bike Crank Set

1. Use a lower gear for starts and climbs. In the same rear gear, a 36T ring moves you about 18% less distance per pedal turn than a 44T ring.
2. Keep some top-end gearing. Compared with a 32T ring, the 36T moves you farther per pedal turn when the route opens up.
3. Keep the crank length that suits you. If your current 170 mm arms feel comfortable, you can change the gearing without changing the pedal circle.

Common Questions

• Q: How do I check whether this 36T crankset fits my bike?
  A: Check that your bike uses a compatible square-taper bottom bracket. The ring measures 152.2 mm across. Check the installed chainline and allow room for the ring and chain beside the chainstay. Both crank arms also need to clear the frame.
• Q: Does 104 BCD describe the size of the chainring?
  A: It describes the 104 mm circle that passes through the centres of the four mounting bolts. Use the 152.2 mm outside diameter when checking frame clearance.
• Q: Is 36T small enough for steep trails?
  A: That depends on your largest rear sprocket. If you regularly run out of low gears on steep or loose climbs, a 32T ring may suit your riding better.
• Q: Why use a narrow-wide chainring on a 1× drivetrain?
  A: The alternating tooth widths match the alternating spaces in a compatible chain. This helps keep the chain seated as you pedal.

Summary

Choose this 36T bike crank set if 170 mm arms suit your fit and your rides mix climbs with faster sections. Check your bottom bracket interface, chainline and frame clearance before fitting.
