5-Day Framebuilding Course

Learn the fundamental skills to build your own bespoke steel frame. Our courses are designed for the absolute beginner, no previous experience is necessary.

Under the supervision of our own master frame builders we will teach you the fundamental skills to actually build your own steel frame and feel confident that you can return to the workshop to make many more.

Mark has been teaching frame building for many years now and has been asked many times to help riders make their own frame. Whilst the allure of the perfect fit and a one-off finish is enough for some, the option of creating your own frame from scratch under the supervision of two master frame builders offers something extra special, as well as group ride bragging rights.

We have been running the courses since day one but are now delighted to be able to offer you the opportunity to do exactly that throughout the year as a part of a comprehensive and customisable package. On our 5-day frame building course, we will welcome you into our workshop and share our enormous wealth of experience with you, to help you create your own tailor-made bicycle frame.

The course will be taught by Reilly Cycleworks own frame builder Mark Reilly. With nearly 30 years experience of building

award-winning frames, Mark's level of knowledge and range of skills are unparalleled, having made titanium popular in the UK, designed mirror polished logos etc and taught more than one award-winning frame builder over the years, his work highly copied.

So whether you’re interested for yourself, or you want to get rid of a loved one for a week after Christmas, get in touch today and guarantee yourself a place!

What You Can Build

On the course, you can build your own custom steel frame. You have the freedom to choose what you want to build and will be involved heavily throughout the design process.

We can teach you to build anything from a sprightly new road or track frame to a mud-loving cross/gravel or hard-tail mountain bike frame or even something to go touring with, the choice is yours. Unfortunately, tandems, recumbents, BMXs and trikes, as well as builds in stainless steel, are too complex to fit into the 5-day course. We are often asked whether you can build a stainless steel frame from 953 or Xcr, the answer is a big emphatic NO!

Upon payment of your course fee (8 weeks prior to the start of the course) we will contact you regarding the design of your frame. We have years of experience building frames and can help you with advice and guidance to make sure you get the most out of the course.

You have the option of the classical styling of a lugged frame, or the smooth, seamless beauty of a fillet brazed construction. When making a fillet brazed frame we always suggest using a cast BB shell and fillet brazing the 3 main joints due to time constraints.
We recommend the following combinations of materials and applications: Touring Frames Reynolds 631, 853 or Columbus Life Road Frames Reynolds 631, 853 or Columbus Life/spirit Track Frames Reynolds 631or Columbus Spirit Mountain Bike Frames Reynolds 631/853 or Columbus Life 29er Mountain Bike FramesColumbus 29’er We also have an account with Dedacciai in Italy should you wish to use their tubes.

Reynolds of course are British whilst Columbus and Dedacciai are made in Italy. All are of equal quality, which is super high end.

We use frame parts from Long Shen in Taiwan, Paragon machine works in the USA and quite recently dropouts from Bentley components, made right here in the UK. Other parts can be specially ordered.

In addition, we can supply forks and parts from Enve, Headsets and Bottom Brackets from Chris King and a whole array of other parts, just ask at the start.

We don’t paint in house as we believe it is far better to use a specialist and use 3 artisan painters, all based in the South East. Many show winning frames will have been painted by one of our chosen painters but prices vary hugely, so again, just ask again at the start.
