Frame Building

Located above & behind our shop is the 3500 sq ft dedicated factory, including the frame room, preparation rooms, machining room, paint booths, baking oven, finishing area and office.

Unlike some so called bike frame manufacturers, we manufacture & paint all our frames in house, using dedicated staff, who have been trained in house to the high standards that a specialist such as ourselves requires.

The corporate memory of the longer serving staff, coupled with the fresh ideas of the younger enthusiasts, mixes to give us a great blend of experience & cutting edge ideology. Whether it is a simple respray, a classic bike restoration or a dream bike project, we are proud of all our work great & small.

Frames can be either Jig built or Free built. Jig built is best used for mass producing low cost frames, as it is the quickest way to produce a high volume in a short space of time. When built in a jig all the tube joins are done in one go and as the tubes are heated they expand, contracting when cooling down. Because this happens at different rates & each tube is clamped in a fixed position the frame becomes stressed & out of line. Once built the frame is then substantially tracked straight (a trade term for bent back in line). As a result a great deal of the latent strength & springiness of the tubing is lost forever.

If time & money were of no consequence all builders would build the way we build our frames. Frames can be built either by machine or by hand. Machine built frames are churned out as quickly as possible with a minimum of time & cost resulting in a cheap, cost effective frame. Any handbuilt frame benefits from the constant quality assessment, care & attention that only a human can apply. The more experienced the builder, the better a job of building the frame he can do, calling on his many years of frame building. Bob Jackson Cycles will only build by hand, in house, by fully trained & experienced builders to ensure the best quality possible.

holes & to ensure we can honour our 5 Year Guarantee all frames are built under no time or cost constraints.

Bob Jackson Cycles uses silver for all braze ons, fittings & frame joins with the exception of Reynolds 853 where due to its unique properties we use brass, heated & cooled at specific rates to heat treat the tube joins & so achieve tensile strengths of over 100tons (twice as strong as 531)!

After all this care & effort in the construction the frame now needs to fit & do exactly what you want. If you are a standard size & require the frame for a particular use we may build an Off The Peg model that will do the job, but if you need something a bit different then the way to go is fully Custom Built.
