Hello Hambini Fans!!!

My name is Arampamoorthy Sachinder Srikantha Sanjeevkumar Varaprasatham Hambinathan, although I am better known as Hambini.

I am a Chartered Engineer and European Engineer. My background is in aerospace engineering, with experience in aerodynamics, gas turbine compressor systems, tribology, mechanical design and manufacturing quality.

I started Hambini Engineering and Hambini Media in 2014. It began as a project in my spare time and has developed into an engineering, manufacturing and media business with an international customer base and audience.

Hambini Engineering

Hambini Engineering designs and manufactures precision bicycle components, with a particular focus on bottom brackets and bearing systems.

Each product is developed around sound engineering principles, accurate alignment and controlled manufacturing tolerances. Particular attention is given to bearing fits, material selection, stiffness, sealing and dimensional consistency. These details directly affect efficiency, reliability and service life.

Hambini Engineering is now the second largest producer of bicycle bottom brackets in the United Kingdom. It supplies international bicycle manufacturers on an OEM basis, as well as individual cyclists throughout the world.

Hambini components are used by everyone from commuters and amateur racers to professional athletes competing at WorldTour, Olympic and World Triathlon level. These are not sponsored placements. The equipment is selected and purchased on its engineering merit.

Hambini Media

The Hambini YouTube channel has more than 125,000 subscribers and is one of the largest independently operated cycling channels in the United Kingdom.

The channel applies aerospace engineering principles to bicycle components, aerodynamics and manufacturing quality. Regular subjects include tribology, bearings, dimensional inspection, wind tunnel testing, product failures and the critical assessment of technical claims.

My presentation can be direct and occasionally irreverent, but the underlying work is based on measurement, established engineering principles and evidence.

Product investigations and recalls

A significant part of my work involves investigating product failures, identifying their underlying engineering causes and communicating the potential consequences to cyclists.

My technical analysis contributed significantly to the scrutiny surrounding Shimano’s bonded Hollowtech II cranksets. The failure mechanism involved separation of the bonded crank structure. Shimano subsequently introduced a worldwide inspection and replacement programme covering more than two million cranksets.

I identified a structural fault in the bonded carbon spokes used across the Ascent wheel range. The adhesive joint between the carbon spoke and its threaded metal end could fail, causing the spoke to separate and the wheel to lose tension. Following publication of my findings, Ascent recalled its entire wheel range.

I also investigated spindle failures affecting Favero Assioma power meter pedals. Favero subsequently introduced a free replacement programme for affected production batches. Favero described this as a voluntary commercial substitution rather than a formal recall.

These cases demonstrate the importance of independent technical scrutiny. Engineering defects should be assessed using physical evidence, failure analysis and appropriate testing, not dismissed because a product comes from a major manufacturer.

My engineering analysis and evidence have also been cited in consumer disputes and legal proceedings within the cycling industry.

Engineering approach

Where I publish results, I explain the equipment, methodology and engineering reasoning behind them. Products are assessed on the available evidence, regardless of the size or reputation of the manufacturer.

My professional registrations carry obligations relating to competence, integrity, accuracy and the responsible communication of technical information. They provide a structured basis for evaluating evidence, recognising uncertainty and separating engineering analysis from marketing.

Thank you for visiting.
