Welcome to Arthur Caygill Cycles

Frame Building

Arthur Caygill Cycles has been established for over 30 years. Historically and present day we manufacture quality frames in our own on site workshop so as to meet customer requirements dependent upon their shape and the type of cycling they will be doing.
Each customer who opts for a made to measure frame is given our full attention; they are physically measured and their requirements are discussed. Advice is offered based on a wealth of experience; Arthur has been very much in the thick of the racing scene for much of his life and continues to be an avid cyclist, so knows what makes a bicycle frame perform.
Customers are offered information regarding frame tubing, lugs, drop outs and braze-ons; they can see first-hand the differences between frame component parts. The good range of tubing and investment cast lugs held promotes informed decisions to be made.
Ensuring the customer is clear and content with all details is paramount to us at Caygills, including finishing colour and any decal detailing. We can cater for almost any finishing and decal requirement from single and multi coloured paint options to name and logo graphics.
All relevant information is captured on a ‘frame design sheet’ and kept for construction purposes and customer historical records. From the request date, delivery date is often several weeks however we will always endeavour to meet any timescales.
Moving forward, work can now begin on frame manufacture.
Each process is meticulously carried out; mitres are hand filed, tubes and lugs are cleaned and bead blasted and all measurements checked and re checked before any brazing occurs. All brazing work is predominantly carried out on a frame jig after individual tubes have been perfectly hand crafted.
Generally Caygill frames are constructed by first manufacturing a series of sub assemblies, this approach has proved totally successful in ensuring that vital accuracy is achieved, allowing individual joints to be concentrated upon.
Briefly the process is as follows. The mitred top tube is joined to the head tube, set at the chosen angle. The seat tube after considering its final length being mindful of its butted section is brazed into the bottom bracket shell. The top tube second mitre is filed to fit to the seat lug and seat tube at the required length and angle. The down tube is now filed accordingly so as to be mitred to fit the head tube of the suitable length and give correct protrusion into the bottom bracket shell for maximum strength.
Once measurements and fit are checked and confirmed and cleaning and fluxing is carried out, the ‘main triangle’ can be brazed, again in the jig. Attention is now given to the other sub assembles; the chosen drop outs are fitted into the chain stays, drop outs fitted into the fork blades and the steerer tube fitted to the desired fork crown.
Utilising the jig, the cut to length chain stay sub assemblies are set at a measurement in correspondence to the central horizontal datum line through the bottom bracket shell, this give the bottom bracket drop and ultimately the bottom bracket height on the road. Once the chain stays are brazed in place it can be seen that the seat stay length is pre determined.
There are many details remaining to complete the frame but we hope this gives an insight to the work and care taken to produce your hand crafted frame that will last providing many years of service.
Frames manufactured recently have included those for a gentleman with a 38 inch inside leg and another frame to suit a rider required a 25 inch top tube eventhough the seat tube was a more typical 21 inches. These are just examples of what can be done.
Currently we are proudly sponsoring Chris Hopkinson. This year amongst many things Chris has achieved a win at Seibring 24 hour event, set records at the UMCA London to Cardiff and the Cardiff to Edinburgh and also won the Ireland 12hr.
Chris rides Caygill custom built bicycles incorporating Caygill frames that have been made to measure to position Chris where he wants to be and so maximise efficient use of his ability.
Caygill Cycles has successfully supported racing teams and individuals and built numerous frames of varying natures for touring and all aspects of cycling. Therefore we firmly believe that if you are looking to a replacement frame we can offer a comprehensive frame building service that rest assured will give the results you are looking for.
