Rear I.s Adapter - Io W/ Mount Bolts
Earn up to Rs. 10.50 cashback with Club House
Description
A small part that does a critical job: the Tektro Rear I.S. Adapter with mount bolts converts an International Standard (I.S.) rear frame mount to accept a post-mount brake caliper. For Indian riders upgrading or replacing brake hardware, having the right adapter means a clean, secure installation — essential when braking confidence matters on Lonavala descents or monsoon-slicked Pune roads.
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
This adapter solves a real-world fitment problem without drama. Indian roads — from the steep Ghats around Coorg and Ooty to the potholed urban stretches of Hyderabad and Chennai — demand that every brake component be properly fitted and torqued. The Tektro Rear I.S. Adapter keeps your caliper aligned correctly, and at Rs. 210 with free delivery above Rs. 2,500, it is one of the better-value brake spares available here.
Sizing for Indian Riders
This is a rear-specific adapter. Before ordering, confirm your frame uses an International Standard (I.S.) rear disc mount — common on many Indian-market MTBs and entry-level road bikes. Also verify the rotor size your caliper supports, as different I.S. adapter variants suit different rotor diameters. When in doubt, check your frame's specification sheet or contact us.
Compatibility Notes
Designed for frames with an I.S. (International Standard) rear disc mount. Works with post-mount brake calipers. Mount bolts are included. Confirm your rotor diameter compatibility before installation. Torque bolts to the caliper manufacturer's specification — under- or over-torquing can cause caliper misalignment and brake rub. Compatible with Tektro disc brake calipers and other standard post-mount designs.
Pairs Well With
Round out your brake service with a compatible post-mount disc brake caliper, replacement disc brake pads suited to your rotor type, a quality torque wrench for correct bolt torque, and brake-specific grease or anti-seize compound for the mount threads.

Frequently Asked Questions
What is the Tektro Rear I.S. Adapter best used for?
This adapter is used when your rear frame has an International Standard (I.S.) disc brake mount but your brake caliper requires a post-mount interface. It is a fitment component — not a performance upgrade — but essential for a correct, safe brake installation on many Indian-market MTBs and hybrid bikes where I.S. mounts are common.
How do I know if this adapter fits my bike?
Check your rear frame's brake mount type. If two vertical bolts attach your caliper directly to the frame, you have an I.S. mount and this adapter is relevant. Also confirm rotor diameter compatibility, as I.S. adapters are size-specific. When in doubt, photograph your mount and contact the Cobbled Climbs team before ordering.
Will this adapter hold up in monsoon conditions and Indian heat?
Yes. The adapter itself is a steel mounting component — it does not degrade from moisture or the 35°C-plus heat common across Pune, Hyderabad, and Chennai. Standard maintenance applies: check bolt torque periodically, and apply anti-seize compound to threads if riding frequently in wet monsoon conditions to prevent corrosion and thread seizure.
How does an I.S. adapter compare to a direct post-mount frame setup?
A direct post-mount frame eliminates the need for an adapter, keeping the caliper mount stiffer and slightly lighter. An I.S. adapter introduces a small additional interface but, when torqued correctly, performs without meaningful difference in real-world braking. For most Indian riders, the functional difference on road or trail is negligible.
Is the Tektro Rear I.S. Adapter worth Rs. 210 and does it carry a warranty?
At Rs. 210 with mount bolts included and free delivery on orders above Rs. 2,500, this is straightforward value — adapters from major brands cost significantly more. Tektro covers manufacturing defects; the adapter should last the life of the frame if correctly installed and bolts are periodically checked for torque. Cash on delivery is available across India.
