Mtr12 10x135mm Quick Release DISC Brake Rear Hub

The Bitex Mtr12 is a 10x135mm quick-release rear hub built for disc brake drivetrains, suited to road, gravel, and mountain bike builds. Precise bearing placement and a reliable engagement system make it a capable foundation for custom wheelbuilds or replacements across India's varied riding terrain — from Pune expressways to monsoon-battered Coorg trails.

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

For Indian riders building or rebuilding wheels, the Bitex Mtr12 is a sensible choice at its price point. The 10x135mm QR standard suits a wide range of older disc-equipped frames, and Bitex's reputation for consistent manufacturing quality means you get predictable bearing performance without overpaying. In the heat and humidity of rides around Hyderabad or Chennai, reliable internals matter more than brand prestige.

Sizing for Indian Riders

This hub uses the 10x135mm quick-release standard — common on older mountain bike and cyclocross frames. Confirm your rear dropout spacing is 135mm (not 130mm road or 142mm thru-axle) before ordering. Disc brake rotor mounting standard — Centerlock or 6-bolt — must also match your existing rotors. Verify cassette body compatibility with your drivetrain before purchase.

Compatibility Notes

Designed for 10x135mm QR disc brake frames. Confirm rotor mounting standard (Centerlock or 6-bolt) matches your rotors. Check cassette body compatibility — Shimano HG, SRAM, or other standards vary by hub spec. Lacing spoke count must match your chosen rim. Clean and inspect bearings periodically, especially after monsoon riding or water crossings.

Pairs Well With

Build this hub into a complete wheel by pairing it with a quality double-walled rim suited to disc brakes, appropriate gauge spokes and nipples, a matching front hub for a paired build, and a disc brake rotor in your preferred standard. Browse compatible components at Cobbled Climbs.
