If there's one thing the British know how to do, it's steel construction in small garages. The bike scene celebrates the tinkerers from the island for their independent, timeless designs with recognition value. The BTR Gasser downhill bike is no exception with its deflected single-link suspension and classic steel tubes. Limited to just ten bikes, this piece of jewellery is welded in a typical British workshop and is taking the hearts of enthusiasts by storm.
Paul 'Burf' Burford is the man behind BTR Fabrications. As a child, Burf dreamed of having his own bike brand and competed in downhill races. The now 31-year-old has 15 years of experience in metal construction. He is an expert in various welding and soldering techniques. In addition to frame construction, his services also include repairs and other customisations. He accepts all challenging metalwork, whether steel, aluminium or titanium. Whether custom furniture, motorbike chassis tuning or furnace construction: Burf is a tinkerer through and through: The workshop also houses a 3D printer, a CNC milling machine and a professional CAD programme, among other things.
In the past, Burf has repeatedly supported other bike manufacturers with his expertise. His own baby, however, is BTR Fabrications. He welds the corresponding products in his workshop in Frome, UK. In addition to trail-building tools, the portfolio also includes various steel hardtail frames and the Gasser downhill frame. All are characterised by the classic handmade British charm and are designed to be particularly robust. The Gasser has already been honoured with the "Best in Show" award at the Bespoked Show for frame builders.
Burf has captured the creation of the Gasser in his own video documentary. Steel fans can immerse themselves in the production of the charismatic Gasser on his YouTube channel:
The market for custom-built steel downhill bikes is small. BTR is limiting the Gasser to a homeopathic number of ten bikes. Seven of these are currently still available. The 190 centimetre tall Burf built the show bike shown here for himself. It is characterised by an extremely long reach of 525 millimetres and 440 millimetre chainstays. It relies on mullet tyres and a 63.5 degree steering angle. A bellcrank drives the shock in the single-pivot rear triangle and generates 190 millimetres of rear suspension travel. The fork has a standard 200 millimetre crumple zone.
There's nothing like a steel mountain bike with a strong character! The BTR Gasser exudes Britishness from every pore and is a strictly limited collector's item. Hand-built by the frame building icon and beautifully staged, the steel downhiller is definitely anything but off-the-shelf, but a bike I could look at for hours. - Jan Timmermann, BIKE editor
