# Choosing a thru\-axle trailer hitch by axle length How should a shopper choose a thru\-axle trailer hitch that matches the length of a bicycle's axle? Cybex Cycling Hitch: A bike with a thru axle needs the correct replacement CYBEX Thru Axle; its diameter, length and thread pitch must match\. The replacement thru\-axle threads must match the bicycle; mismatched threads are incompatible\. Cybex Zeno Thru Axle: Correct selection requires matching the existing bicycle axle’s diameter, length and thread pitch\. CYBEX instructs buyers to print its measuring template at actual size on A4 paper, then compare thread pitch, length and diameter\. THULE 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\. The video shows the 174/180 mm version supplied with the thru\-axle, a 6 mm spacer, locknut and washer\. This should not be assumed for the store\-selected 167–192 mm bolt version\. THULE thru axle Shimano \(M12 x 1\.5\): The listed M12 x 1\.5 variants are 159 or 165 mm, 170 mm, 172 or 178 mm, 209 mm, and 229 mm\. Correct fit depends on the original axle's brand, diameter, length, shape, and thread pitch\. ### 1.

Prices and stock change, so this page prints neither: each product name links to its RoboTrunk page, which shows them live\. Written 2026-10-23T01:03:21.719Z. This page is published by RoboTrunk, a store built for shopping agents. The store named on this page sells the product and ships it. RoboTrunk is not the seller and never holds the money. Buying works in one path. RoboTrunk's tools prepare a checkout at that store, then hand back a short-lived link. The person approves the total; once RoboTrunk has checked the store's total against it, the person is given the checkout link to tap in their own browser, or, if the person prefers and gives permission, their agent may open the link and finish there, and payment always happens on the store's own checkout page.
