Description
The Rohloff Monkey Bone 160mm Adapter converts an IS (International Standard) brake mount to a Post Mount (PM) interface, allowing you to run a 160mm rotor on frames and forks that would otherwise require a different caliper. It is the kind of small component that makes a significant difference when building or upgrading a bike for the varied road surfaces, steep descents, and monsoon conditions found across India.
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 riders tackling the Western Ghats, the Lonavala–Khandala descent, or the long switchbacks above Ooty, having the correct brake mount adapter is non-negotiable. The Rohloff Monkey Bone IS-to-PM 160mm Adapter ensures your caliper sits exactly where it should, giving you consistent braking geometry and confident modulation when conditions get wet or demanding. Precision machining at this price point from Rohloff is genuinely good value.
Sizing for Indian Riders
This adapter is specifically dimensioned for a 160mm rotor. Before ordering, confirm your frame or fork uses an IS mount and that your caliper is a Post Mount design. Rotor diameter must match the adapter spec — do not use this with 140mm or 180mm rotors. In India's high-heat summers above 35°C, correct adapter fitment also aids caliper alignment and heat management.
Compatibility Notes
Works with IS-mount frames or forks paired with Post Mount disc brake calipers at 160mm rotor diameter. Not compatible with flat-mount or direct-mount standards. Torque bolts to manufacturer specification — over-tightening can crack the adapter. Check for frame mount thread condition before fitting. Compatible with both mechanical and hydraulic disc caliper types sharing the PM standard.
Pairs Well With
Complete your brake setup by pairing this adapter with a quality 160mm disc rotor, compatible IS or PM disc brake caliper, stainless mounting bolts, and a torque wrench for precise installation. If upgrading hydraulic calipers, a bleed kit and appropriate brake fluid round out the build.

Frequently Asked Questions
What is the Rohloff Monkey Bone 160mm Adapter best used for?
It is best used when your frame or fork has an International Standard (IS) brake mount but your disc brake caliper requires a Post Mount (PM) interface at 160mm rotor diameter. Common in mountain bike and gravel builds, it is particularly useful for Indian riders upgrading braking systems for Ghat descents or monsoon riding without replacing the entire frame.
How do I know which adapter size to order for my setup?
Check your frame or fork's brake mount standard — IS (International Standard) mounts have two bolt holes spaced further apart. Then confirm your caliper is Post Mount and your rotor is 160mm. If your rotor is 140mm or 180mm, you will need a different adapter. When in doubt, consult your frame's specification sheet or contact the Cobbled Climbs team for guidance.
Will this adapter hold up in monsoon conditions and Indian summer heat above 35°C?
Yes. The Rohloff Monkey Bone adapter is precision-machined to stay correctly aligned under the heat and humidity typical of Indian monsoon riding and summer temperatures above 35°C. Correct torque on the mounting bolts is essential — check them periodically after riding in wet conditions, as water ingress can loosen fasteners on unpaved or rough road surfaces common across India.
How does this IS-to-PM adapter compare to a flat-mount adapter?
IS-to-PM adapters suit older mountain and gravel frame standards, while flat-mount adapters are designed for modern road and gravel frames with the newer flat-mount caliper interface. These are not interchangeable. The Monkey Bone IS-to-PM is the correct choice only when your frame has IS mounts and your caliper is Post Mount — flat-mount frames require a completely different adapter type.
Is the Rohloff Monkey Bone adapter worth Rs. 3,800, and does it carry a warranty?
At Rs. 3,800, this is a precision component from a German manufacturer with a reputation built on exacting tolerances. Getting caliper alignment right protects far more expensive brake calipers and rotors. Warranty terms follow Rohloff's standard product policy — contact Cobbled Climbs for specific warranty queries. Free delivery applies on orders above Rs. 2,500, and cash on delivery is available across India.
