Bespoked - a celebration of handmade bicycles & those who make them

The Steel Bicycle Project (TSBP)

the steel bicycle project

The International Bicycle Engineering Research Group (IBERG) is a collection of engineers and scientists who are active in the field of academic and industrial research relating to bicycles. Founded in 2014, IBERG aims to promote the technical aspects of bicycle engineering and to generate new knowledge in this field. At Bespoked 2019, IBERG will launch the steel bicycle project (TSBP) which aims to raise awareness of key engineering and scientific principles that relate to steel bicycle design and through this project IBERG aims to work with the community of frame builders to help them gain access to useful scientific measurements.

Fillet brazed joint tube failure

The International Bicycle Engineering Research Group (IBERG www.iberg-bike.org ) is a collection of engineers and scientists who are active in the field of academic and industrial research relating to bicycles. Founded in 2014, the IBERG aims to promote the technical aspects of bicycle engineering and technology and to provide a collaborative environment for generating and disseminating new knowledge in the field. At Bespoked Bristol this year, we will launch the Steel Bicycle Project (TSBP) which aims to raise awareness of key scientific and engineering principles that relate to steel bicycle design. One of the first things we want to do is to understand the needs of frame builders in their quest to design and fabricate even better bicycles. For instance, some early projects we’ve already started to work on include looking at fillet brazed joints under an electron microscope to look at the heat affected zone and the intermetallic bonds for various brazing alloys used under different conditions. We have also carried out some tests to look at how these brazing alloys influence the frame strength over the life of the bicycle. We are also keen to understand what the public want when it comes to buying a new bicycle: what are their expectations with regard to safety and product testing? Ultimately we want to support frame builders by developing experimental test rigs, carrying out scientific testing and developing complementary numerical simulations to help them build the best, strongest, and most robust bicycles possible. This will allow us to generate and publish data that is useful for the industry and that is available for all in the public domain. We want to use this data to help raise awareness in the public and in the industry about relevant topics such as key material properties, to demonstrate the value of taking scientific measurements and to highlight relevant findings of evidence-based research including the debunking of some commonly held myths! The IBERG will be exhibiting at Bespoked Bristol for the first time in 2019 including some live demonstrations thanks to the generous support from the International Sports Engineering Association (ISEA). We hope that this is the start of a long term project to promote and support the steel bicycle industry for many years to come!
