Tektro Flat Mount Adapter Set 140-140 / 140-160 mm
The Tektro Flat Mount Adapter Set 140-140 / 140-160 mm gives you the front and rear flat-mount adapters in one order, for flat-mount disc brakes running 140 mm and 160 mm rotors, as stated in the set name.
Why this adapter set?
Front and rear together. One item covers both brakes, so you do not have to order the adapters one by one.
Flat-mount specific. Keeps the compact, low-profile look of flat-mount brakes on road and gravel bikes.
140 mm and 160 mm rotors. The set is named for 140 mm and 160 mm rotor setups.
Tektro quality. From the maker of the MD-C550 and other flat-mount brakes we sell.

What the adapter does
1 – flat mount on the frame or fork, 2 – adapter, 3 – caliper, 4 – rotor.
The adapter positions the caliper for the rotor size.
Who is it for?
- Frame and fork builders. Building a flat-mount bike from a bare frame and fork, or rebuilding after a frame or fork change? Get the front and rear adapters together.
- Riders planning ahead. Running 140 mm rotors but may want 160 mm later? The set is named for 140 mm and 160 mm rotor setups.
- Tourers and workshops. Spares for a long tour, or flat-mount adapters kept in stock: one set covers front and rear.
