Mtr12 12x135mm Thru Axle DISC Brake Rear Hub

The Bitex Mtr12 is a 12x135mm thru-axle disc brake rear hub built for riders who demand precision engineering at the wheel's core. Whether you're building a dedicated MTB wheelset for trails around Coorg or assembling a gravel setup for the varied roads between Pune and Lonavala, the hub you choose defines long-term reliability, bearing life, and ride feel.

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

Bitex has quietly earned a strong reputation among custom wheel builders, and the Mtr12 makes a compelling case for itself. The 12x135mm thru-axle standard offers a stiffer rear triangle connection than quick-release — a real advantage on the rougher road surfaces common across Hyderabad and Chennai. For Indian riders building a wheelset from scratch, specifying a quality hub from the start is far smarter than replacing a cheap one later.

Sizing for Indian Riders

Hub sizing is about matching three standards: axle (this hub is 12x135mm thru-axle), disc brake interface (confirm Centerlock or 6-bolt against your rotor), and cassette body compatibility (Shimano HG or others). The 135mm spacing suits specific MTB and some gravel frames — confirm your rear dropout spacing before ordering. Indian summers above 35°C do not affect hub compatibility, but regular bearing checks after monsoon riding are advised.

Compatibility Notes

The Mtr12 uses a 12x135mm thru-axle standard — confirm this matches your frame's rear dropout specification before purchase. Verify disc brake interface (Centerlock or 6-bolt) and cassette body type. This hub is designed for disc brake use only; it is not compatible with rim brake builds. Pair with a rim that matches your intended spoke count and lacing pattern.

Pairs Well With

To complete your custom wheel build, consider pairing the Mtr12 with a quality double-walled rim suited to your terrain, stainless steel or bladed spokes, alloy nipples, and a precision spoke tension meter for accurate wheel building. A torque wrench is essential for correct thru-axle installation.
