The above picture is the relevant dimensions of the brake handle. If you still have any unfamiliar dimensions, please contact customer service and we will measure the relevant dimensions for you!
Please check the above dimensions carefully. Under normal circumstances, mountain bikes are universal. Because the size and structure are not suitable, it is not a quality problem. We do not accept returns or exchanges. Special attention is that this brake can only be adapted to the left brake disc. Please do not buy this on the right. Choose other special brakes for right brake discs in the store or contact us!
The gap between the pads is about 2.7mm 
The way the brake handle cuts off the power is magnetic induction, and the connector of the power cord is a waterproof 2-pin structure with a length of about 200mm.
The main material of the brake handle is aluminum alloy, which is refined by forging process. The appearance and texture of the polished and frosted anode are very good!
The hydraulic brake lever is an integrated oil cylinder structure, which is durable and does not leak oil!
