Trainer Thru Axle 12 x 183mm with Nut
This replacement rear thru axle allows a compatible bicycle to be securely mounted to a wheel-on indoor trainer that requires exposed axle ends or a trainer-specific axle.
The axle has a 12mm diameter, an overall length of 183mm and an M12 x 2.0 thread with a 35mm threaded section. A matching securing nut is included.
Designed for Indoor Trainers
Standard flush-fitting thru axles may not provide suitable attachment points for traditional wheel-on trainers. A trainer axle provides the required external interface while securing the rear wheel correctly in the bicycle frame.
Compatibility Must Be Checked Carefully
Thru axles with the same 12mm diameter can have different overall lengths, thread pitches and threaded-section lengths. All measurements must match the bicycle frame before installation.
This axle is listed for compatible bicycles from model years 2020–2027. The model-year range alone does not guarantee compatibility.
