Front Axle Measurement
N.B. Hope Fork Thru Axles may not fit all the specified manufacturers fork models, it is best to measure and check your fork axle and compare the dimensions and specifications to the drawings below.
Remove your fork thru axle from your bike. Most Fox and RockShox trail forks use a flat head interface whilst Ohlins use a pinch bolt on the drive side to secure the thru axle.
This can vary depending on each manufacturers fork model.
Measure the insertion length of your thru axle and using the drawings below ensure the insertion length is correct.
Check your thread dimensions ensuring the thread outer diameter and length match your fork thru axle.
Rear Axle Measurement
Remove the stock thru axle from your bike.
Make a note of your thru axles interface with the bikes, ie if there is a taper / tapered washer or flat / flat washer behind the head of your axle.
Measure the insertion length of your thru axle leaving any washers that your axles may use in place and make a note of the insertion length. See depiction below showing how to measure your thru axle.
Ensure your thru axle has an M12 x 1mm thread. All bikes that use a SRAM UDH or SRAM Transmission drop out are compatible with Hope Thru Axles.
Finally use the measurements and information you have to work out which axle you might need from the chart below.
N.B. If your axle insertion length is shorter or longer, then unfortunately Hope don't manufacture a thru axle to suit your bike.
