Sarto have been producing for over 35 years light weight bicycle frames. Sarto have always been at the forefront of technology, and have recently built a new factory for producing carbon frames. We build frames for industry, and we make individual frames for Professional team riders who require something other than a standard frame.

Sarto’s reputation continues to grow within the industry and among professional riders who require high-end custom carbon frames. Our carbon racing frames with custom geometry equip some of the leading riders, and Sarto have always produced custom frames especially for those riders who required something different. Our frames stand apart from frames which, although hand-built with correct geometry, are so similar to each other that it is difficult to recognise the difference between the brands.

The difference between Sarto Carbon Racing frames and other carbon frame manufacturers is that Sarto produce their own tubes in any shape required. Because they produce their own tubes they can replicate those of other manufacturers which allow the frame to look similar to the other team bikes, once painted with the other brands’ colour schemes. Because of this ability a Sarto can always be aesthetically different from more commercially-available tubes and lugs, or even tube to tube designs.

The process and techniques that Sarto use to produce their custom race frames takes up to 10 times more in man hours than most stock frames. After tube production the carbon tubes are cut to spec and hand-finished in every detail, and then set in a jig at the correct, specified angles. Once set they are tacked with resin and the rear stays are set, and after this the joints, tubes etc., are hand-finished. After this comes the Carbon lay up, which entails reinforcing the bottom bracket area with extra strength, and also the vertical tubes where they join the head tube, and any other particular area the rider prefers for his requirements – e.g. if he/she is a rouler, sprinter, climber or lone escapee. These various layers are all hand-cut to fit the area and add stiffness, strength and impact resistance. The quantity, size and shape all differ to help tune the final frame performance. Finally, the top layer is completed according to customer requirement, and the weave pattern of 1K, 3K, 12K, weave patterns, etc., is added

This process differs relatively little from standard frames in that for standard frames numerous tubes are cut to the same length at one time. For bespoke frames each tube is cut individually and mitred to fit the adjoining tube exactly. Standard frames do not usually go through the same process of additional laying-up, and tend instead to be finished off with fillers and painted over. Some standard frames are set using moulds for the front triangle rather than tacking each individual joint, thereby cutting down on time taken. All this does not mean stock frames are no good – they are, but they take far fewer production steps, which reduces the overall cost. Sarto are quite exceptional in having a background and experience of steel frames, and this technology goes into their CARBON FRAMES when you consider the number of stages needed to produce a frame specifically for an individual or small production runs for high-end industry applications.
