The Dia-Compe MX121 Brake Lever is a simple, lightweight and practical brake lever suitable for BMX, city bikes, single speed bikes and flat bar setups.
The MX121 follows Dia-Compe’s practical and reliable brake component design. Its clean shape works well with different frames and handlebar styles, making it suitable for adding a brake to a single speed bike, replacing a worn BMX lever or upgrading brake control on a city commuter.
This model is available in 22.2mm / 23.8mm clamp sizes. The 22.2mm size is commonly used on flat bars, BMX bars and some city handlebars, while 23.8mm can fit certain specific handlebar or brake lever setups. Please confirm the actual handlebar diameter before ordering.
The silver version gives a classic metallic look and pairs well with vintage or polished component setups. The black version offers a clean and understated appearance for modern or minimal builds. This product includes one brake lever only, so please order the required quantity according to your front brake, rear brake or left / right setup.
If you are looking for a simple, easy-to-match and reliable brake lever for flat bar use, the Dia-Compe MX121 is a solid option.
⚠️ Please note: this product includes one brake lever only, not a pair.
⚠️ Brake cable, outer housing, brake caliper and other parts are not included.
⚠️ Please confirm your handlebar mounting diameter is 22.2mm or 23.8mm before purchase.
⚠️ Brake systems affect riding safety. Professional installation and adjustment are recommended.
