DCTech BSA Shimano Road Ceramic is compatible with BSA frames for Shimano Road cranks with a 68 mm bottom bracket.

DualCupTech
Automatically aligns the bearing surfaces regardless of external factors. Alignment between the bearings on both sides is crucial, and special attention is paid during the manufacturing process to minimize this concentricity value. The result is incredible: an extremely smooth pedal stroke from day one.

DualCupTech
Not only can it self-align the bearings, but it also creates a solid central joint without the need for threads or monoblock design. The result after assembly is that the bottom bracket functions as a solid piece and eliminates any noise or movement issues.

It can be installed and removed like any other bottom bracket, without the need for special tools or complex instructions.

Ceramic ball bearings
Experienced manufacturer of high-performance bearings. Ceramic ball bearings offer superior corrosion resistance, greater dimensional stability, lower density, and higher heat resistance. All this results in a more efficient material for bottom brackets.

Fully sealed
Every dust particle or drop of water is a potential cause of noise or bearing wear. That’s why all our bottom brackets are equipped with up to five O-rings to keep dust, water, mud, and moisture out of the bottom bracket.

Axial seals
All our bearings are equipped with not one but TWO seals to protect against dust and moisture. This section is essential to ensure maximum durability and performance of the bottom bracket.

T6 heat treatment
For most aluminum alloys: 6061, 6063, and 7075, the best heat treatment is T6. T6 heat treatment ensures greater hardness and other mechanical properties, such as grain structure normalization. This guarantees that all our aluminum products perform perfectly throughout their lifespan.
