MEROCA Hidden Quick Release Thru-Axle for MTB/Road - 12mm/15mm, P1.5 P

Product Description

Overview

The MEROCA Hidden Quick Release Thru-Axle is the ultimate upgrade for modern disc-brake MTB and Road bikes. Crafted from high-strength aluminum alloy with precision CNC machining, it replaces bulky external levers with a sleek, concealed handle that protects against impacts. Featuring standard P1.5 thread pitch, multiple 12mm/15mm diameters, and comprehensive length options (including Boost 148 and 142 rear spacing), this thru-axle ensures rock-solid wheel retention, zero-slip threads, and a cleaner cockpit profile.

Key Features

✅ Hidden Concealed Lever Design – The quick-release handle retracts inside the axle body for a sleek aesthetic and prevents accidental strikes on trails or during transport.

✅ Precision P1.5 Thread Pitch – Clear, accurate M12/M15 × 1.5mm threading ensures tight meshing, reduces loosening, and prevents thread stripping.

✅ Aluminum Alloy + CNC Machining – Exceptional strength-to-weight ratio; resists deformation under rough terrain and high-speed vibration.

✅ Dual Installation Method – Use the hidden lever for tool-free convenience, or the hex socket at the axle end (8-10Nm torque) for precise tightening.

✅ Copper Adjustment Washer – Included shim compensates for concave frame/fork dropouts, ensuring a perfectly flush, secure fit.

✅ Full Size Coverage – 12mm (100mm/142mm/148mm Boost) and 15mm (100/110mm front) options with exact lengths from 117mm to 181mm.

✅ Lightweight – Ranges from ~46.6g to ~87g depending on specification.
