Description
The Tektro Rear I.S. Adapter is a precision-machined mounting component that bridges International Standard (I.S.) brake mounts to compatible Tektro hydraulic disc brake calipers — specifically the Orion, Auriga Comp, Volans, Sub, E-Sub, Twin, and Lyra series. Includes the necessary mount bolt for a complete, secure installation on your rear frame mount.
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 running Tektro hydraulic disc brakes, getting the adapter right is non-negotiable. Whether you're descending the Western Ghats near Pune, navigating Lonavala switchbacks, or braking hard in Hyderabad traffic, a mismatched or missing I.S. adapter undermines your entire brake system. This OEM Tektro part ensures correct caliper alignment, consistent pad contact, and predictable modulation — exactly what you need when roads are slick with monsoon rain.
Sizing for Indian Riders
This adapter is specifically designed for Tektro I.S. (International Standard) rear frame mounts. Confirm your frame uses I.S. mounting — not post-mount or flat-mount — before ordering. Rotor size compatibility depends on which specific caliper model you run, so cross-check your Tektro caliper model against the listed compatible series. When in doubt, check your frame documentation or contact our team.
Compatibility Notes
Compatible with Tektro Orion, Auriga Comp, Volans, Sub, E-Sub, Twin, and Lyra hydraulic disc brake calipers on International Standard rear mounts. The included mount bolt ensures a secure fit. Tighten to manufacturer-specified torque — do not overtighten, as this can distort the caliper mount and cause brake rub. Use a calibrated torque wrench for installation.
Pairs Well With
Complete your brake service with compatible Tektro brake pads matched to your rotor type, a quality torque wrench for correct installation, a hydraulic bleed kit suited to your Tektro caliper, and replacement brake hose and fittings if you're doing a full service.

Frequently Asked Questions
What is the Tektro Rear I.S. Adapter best used for?
This adapter is a service and replacement part that mounts compatible Tektro hydraulic disc brake calipers — Orion, Auriga Comp, Volans, Sub, E-Sub, Twin, and Lyra — to International Standard rear frame mounts. It's essential when replacing a lost or damaged original adapter, or when building up a frameset that uses I.S. mounts with a Tektro hydraulic caliper.
How do I know if this adapter fits my frame?
You need a rear International Standard (I.S.) brake mount on your frame. I.S. mounts have threads that face the side of the frame, as opposed to post-mounts where bolts thread forward. Check your frame's manual or look up the frame model online. This adapter does not work with post-mount or flat-mount frames. Contact Cobbled Climbs if you need help identifying your mount type.
Will this adapter hold up in monsoon conditions and Indian heat?
Yes. As a machined metal mounting component, this adapter is unaffected by water, humidity, or temperatures above 35°C. Monsoon riding in Mumbai, Pune, or Chennai won't compromise the hardware. Apply a small amount of anti-seize compound to the mount bolt threads before installation if you ride in wet conditions frequently — this prevents corrosion bonding and makes future removal easier.
How does an I.S. adapter compare to a post-mount setup?
International Standard and post-mount are simply different frame mount standards — neither is inherently superior for braking performance. The adapter bridges the I.S. frame mount to the caliper, functioning identically to a direct post-mount once installed. Braking power is determined by your caliper and rotor, not the mount standard. The key is using the correct adapter for your specific frame and caliper combination.
Is this adapter worth Rs. 320, and does it include a warranty?
At Rs. 320, this is genuine Tektro OEM hardware — not a generic aftermarket part. For a component that directly affects brake caliper alignment and therefore your stopping safety, using the correct branded adapter is worth the cost. Tektro's standard warranty applies; for warranty queries on parts purchased through Cobbled Climbs, contact our support team. Free delivery applies on orders above Rs. 2,500.
