Mtr12 12x142mm Rear Hub Conversion Axle

The Bitex Mtr12 is a 12x142mm rear hub conversion axle designed to update older hubs or replace a damaged thru-axle with a properly engineered alternative. For Indian riders running disc-brake builds across Pune's climbs, Delhi's urban grind, or Ooty's descents, a secure, well-fitting rear axle is a fundamental safety and performance component worth getting right.

Use Cases

Daily training. Reliable use across Indian training conditions — heat, humidity, and rough tarmac.

Race day. Performance-grade construction for competitive efforts.

Long rides. Built for full-day rides across Western Ghats, Sahyadri, or Nilgiri climbs.

Our Take

The Bitex Mtr12 does exactly what a good axle should: it fits precisely, stays put, and asks nothing of you once installed. For riders in high-heat, high-humidity conditions across Chennai or Hyderabad, metal-on-metal interfaces benefit from Bitex's precision machining — there's no flex, no creak, and no guesswork. At Rs. 1,000 with free delivery above Rs. 2,500, this is a smart, no-fuss upgrade or replacement for any 12x142mm rear hub.

Sizing for Indian Riders

This axle is specifically 12x142mm — the standard thru-axle format for most modern road disc and gravel rear hubs. Confirm your frame's rear dropout spacing (142mm) and axle diameter (12mm) before ordering. European hub standards apply universally here, so no India-specific sizing adjustment is needed. If unsure, check your existing axle's markings or your bike's original spec sheet.

Compatibility Notes

Designed for 12x142mm rear hub standards common to road disc and gravel frames. Works with Bitex hubs and most third-party hubs sharing the same standard. Confirm thread pitch and end-cap compatibility with your specific hub shell before fitting. Clean the threads and apply a light grease on installation to prevent seizing, especially important in monsoon-season humidity.

Pairs Well With

Complete your wheel service kit with a quality rear hub from the wheels category, bearing press tools, hub-compatible end caps, and a durable anti-seize or assembly grease. Riders rebuilding a wheel around a Bitex hub will also want to consider spoke nipples and rim tape.
