  "title": "Measuring a bike's rear axle to choose a matching thru axle for a trailer hitch",
  "question": "How should a bike owner measure the rear axle to choose the correct thru axle for a bike trailer hitch?",
  "answer": "Cybex Zeno Thru Axle: CYBEX instructs buyers to print its measuring template at actual size on A4 paper, then compare thread pitch, length and diameter. Correct selection requires matching the existing bicycle axle’s diameter, length and thread pitch. The replacement axle is incompatible if its threads do not match those of the removed axle.\nThule thru axle Shimano (M12 x 1.5): Correct fit depends on the original axle's brand, diameter, length, shape, and thread pitch.\nTHULE thru axle Maxle (M12 x 1.75): Maxle part 20100799 fits a 167–192 mm axle range, has a 212 mm overall length and M12 x 1.75 thread pitch, and uses bolt installation.",
