Designed for 12-speed HG chains, the FC-RX610-1 delivers smooth, precise shifting across a broad gear range, whether paired with a 10-45t or 10-51t cassette (cassettes and chainring sold separately).

Components & Technology:

- Spindle Interface: Shimano Hollowtech II spindle interface ensures robust compatibility and easy installation.

- Chainring: 40t chainring with Shimano Asymmetric 110mm BCD allows for wide-range gearing and compatibility with various rings for customized setups.

- Q-Factor & Chainline: Features a 151mm Q-factor for optimal pedaling stance and a 49.7mm chainline suitable for disc brake MTB and gravel hubs.

- Compatibility: Fits 135/142 mm thru-axle road disc hubs, making it versatile for different bike frames and wheelsets.

Style & Use Case:

The sleek black finish complements any gravel or adventure bike aesthetic, offering a professional, minimalist look.
