Baum Track Bike – Todd Knight, Australia — Concept — Omnium/all round track bike. This bike is designed for the great wheel races of Australia. It is designed to be ridden on the flat outdoor tracks of country Australia to the steeply banked wooden indoor velodromes. Finished to match Rapha/Focus kit requested by the customer. This bike can be fitted with Lightweight brand track wheels or the new toroidal bulge disk rear wheels. The Lightweight track wheels will allow use in outdoor velodromes (where there can be wind). — Material — Titanium 3Al/2.5V CWSR Seamless Grade 9. Each tube individually butted to suit the rider (done in house). Titanium 6Al/3V small parts (dropouts, cable stops, bottom bracket). Carbon fork (Enve track) Pewter head badge PPG Automotive paint — Design — One piece stem/bars. Changing the bar/stem combination allows for racing in a range of events from handicaps to madisons. Small bottom bracket drop to allow for pedal clearance on steeply banked tracks Large tube diameters and minimal butting to give a super responsive feel. Carbon sleeve in the seat tube to fit a 31.6mm seat post, a readily available size. TT butting is designed to cope with accidental bar strike — Construction Process — Each bike is made from start to finish in one hit with several people being involved in the manufacturing process. We do not pre-butt and pre- mitre tubes because each bike is highly customised. Our team takes a lot of pride in building desirable, high quality bicycles in an efficient manner. We have created a production system that allows for customisation, efficiency and high quality. Customisation means each bike has custom geometry, tubes, finish and parts. The tubes are selected from a range of diameters (44.5mm, 38mm, 35mm for the down tube for example) which can be butted to a range of wall thicknesses down to 0.6mm. There is a wide range of paint schemes from which to choose and there are 33 standard colours and tens of thousands of custom colours. Our production systems must be flexible enough to allow for this customisation and to incorporate all our models and design changes that happen over time. They must also allow us to be as efficient as possible. We achieve the efficiency and flexibility by designing jigs and machining stations that are used for one process only (e.g. drilling bidon holes) and have a wide range of adjustment. High quality is a combination of getting the same output every time and being able to control what that output is. For example, if an angle is to be 30.7 degrees, I want the output to always be 30.7 degrees and I want to be able to control whether it is 30.7 degrees or 30.8 degrees. Our custom built machining stations and jigs ensure the that desired high quality can be achieved with ease. — Finish — All finishing is done in house. The paint finish is all paint – no decals are used. This requires a complex process of masking, spraying colour and spraying clear coat. PPG automotive paints are used for their range of available colours and the durability of the paint. The absence of stone and chain chips on a track bike allow us to paint the whole frame. Matching post and stem — Delivery Process — Complete bike to be picked up by the customer. — Special Notes — The customer who ordered this bike requested we design a Rapha/Focus riding kit inspired the paint scheme. As he is a great supporter of ours, we were happy to comply and we feel the final result is a tough track bike with classic looks.
