Dekerf Philosophy
Dekerf Cycles was founded through the uniting of two passions, the first being a passion for building things by hand. By this we mean the bringing together of traditional hand skills, with modern equipment, and innovative designs. The second passion is for riding bicycles. We believe there is no substitute for gaining appreciation for what our customers want in a bike frame, than by passionately riding one ourselves. These two passions, building and riding, are the foundation of Dekerf Cycles.

We make each Dekerf frame here in our Vancouver factory. Right from cutting the tubes, to applying the paint, and putting them in a shipping box, we take the kind of pride and care that cannot be achieved in a mass produced frame.
  We also believe in the idea that it's important for smaller companies like ours to exist and build domestically made products instead of farming it out to the lowest bidder with the cheapest labor and lowest environmental standards. When you buy a Dekerf, you're buying a product you can keep for a lifetime, not throw out or need to be upgraded next year. You're also buying something that's beautiful, which is something we need more of in this world. Buy a Dekerf, ride it, keep it, and love it! See you on the trails.

Dekerf History
1991: Dekerf Cycle Innovations was incorporated by Chris DeKerf, the principal framebuilder and designer whose frames bear his name. Chris was the head of the handbuilt division of Rocky Mountain when the need to create and design without the constraints of a large company compelled him to venture out on his own. The initial years of the company consisted mainly of a high end fabrication shop working on a contract basis for larger manufactures including, ironically, Rocky Mountain.

1993: the Dekerf 'Mountain' frame was launched. It had no real model name due to the fact that is was the only model offered and there was nothing else to get it mixed up with.

1994: The Softride road frame was introduced, bringing the Dekerf line to two. The ever popular Tangerine and Emerald Green colors were the only colors offered.

1995: A change in the road frame brought back a Columbus Neuron traditional 'double-diamond' lugged road frame. The mountain bike frame was now officially called the 'Dekerf Mountain' frame, because of the introduction of our first full suspension frame, the 'Dekerf Suspension'.

1996: The Generation year. This type of frame had been requested for al long time - a Dekerf at a lower price point. Oddly enough, the popularity of the 'Generation' increased the popularity of the 'Dekerf Mountain' (now called the 'Dekerf Team' because of the added cool factor). 1996 also saw the suspension frame using a 100% Dekerf designed and built system, taking 1st and 2nd in the Canada Cup Mens Pro Elite Downhill Series, and 2nd overall in the overall Womens.

1997: The year of the funny brochure. Big changes here for the flagship hardtail for the first time in four years. The biggest being the switch to the UK made wonder steel, Reynolds 853, for the main triangle. There was also a switch to a lighter investment cast dropout. As a result of the dropout switch, the tops of the seat stays, which had traditionally been left open, were now closed off with a small, black plastic cap. The frame was renamed the 'Team SL'.

1998: The Team SL got a further refinement with the addition of Reynolds 853 chainstays. The Generation also joined the Reynolds family by being constructed of Reynolds 725. The road frame ('Prodigy') was back, also sporting a Reynolds 853 main triangle and chainstays. The most talked about frame for 1998 was the Team ST - the softtail. This frame used a steel spring in the monostay and special chainstays from Ritchey to provide almost an inch of travel on an otherwise hardtail frame.
  1999: With supply problems hampering the availability of the steel chainstays that we used in 1998, we had proceeded on putting into production an idea whose time had come for the 1999 frame. We replaced the steel chainstay with a titanium version. In a page of the July issue of BIKE magazine, Mike Ferrentino referred to the '99 version of the ST as the 'best handling bike in the world', and created a feverish demand for this new version of the frame. The 'Generation' also gets onto the air-hardening wagon by switching to Reynolds 631 tuning, the little brother to 853.

2000: Three new models and one new address. For 2000, our expansion into paint-booth friendly premises in sunny Richmond also allowed us to introduce our first ever titanium models: the Team SL TI and the Prodigy ST TI. Our steel lineup has been augmented by the Implant (no pun intended), our beefy out-of-bounds hardtail. The addition of a wet paint booth to our facilities is a great leap forward in the control and management of our production. What you may gather from this is that over the course of our first ten years, Dekerf has been in a relatively constant state of expansion in terms of production, models, shop space and staff. That is testament to the creativity and vision of Chris Dekerf and to the passion and labour which has been invested in every bike which leaves the premises.

2001: Dekerf celebrated it's Tenth Anniversary, and though that's seventy in dog years, we're not ready to turn in the welding torches for Bingo dabbers. We celebrated the occasion by producing a tasty custom beer, the legendary Dekerf Bug Juice, and we introduced our first Aluminum models: the Team 7000, the Prodigy Scandium and the full-suspension Phenomenon. With the retirement of the Generation and the Singlespeed's mutation into the Solitaire, all of Dekerf's steel models are now made from Reynolds 853 tubing. Dekerf's paint offerings expanded to include jaw-dropping flames and fades among a range of custom options. Second Decade and still growing!

2007: We relaunched and revised a number of frames, making them better than ever.

Today: We're still going strong, looking forward to building your dream bike!

Building and Alignment
Dekerf stands alone in its commitment to perfect alignment and geometric accuracy. When a mass-produced frame is assembled, the entire frame is welded together and then cold set to achieve an acceptable level of straightness. However metal has a memory and a cold set frame will eventually work it way back to its pre-aligned state. At Dekerf, frame alignment is meticulously checked after each individual tube is worked on. This allows the welder to alter the welding pattern and 'pull' the frame back straight without using force. Our frames are examined for accuracy over ten times before they even reach the final alignment table. Our frames are made straight and will stay straight-forever!

Dekerf Seat Collar Assembly
The top of the seat tube on the Team853 is made of a separate non heat treated cro-moly collar. This collar is machined externally for weight reduction and internally to ensure a highly accurate fit on the seat post. The collar provides a strong joining surface for the top tube, seat tube and the wishbone assembly.
  As the collar is non-heat treated the many welds in that area do not affect it. This also works in the reverse- if the tube is damages repairs can be made without affecting the structural integrity of the joints. For the same reason the head tube and bottom bracket shell is also not heat-treated.

Pierced Monostay Assembly
The Dekerf wishbone design is based on the principle of maintaining the heat-treated tube's natural strength by neither bending it nor overheating it, as is often done with traditional designs. The seatstays pierce the precision bored wishbone arms tightly and are then joined using low-temperature silver solder that thoroughly penetrates and bond the joints with the original heat treatment of the tubes. This joins the structure together creating. The assembly is thus both a mechanical and welded joint; a completely unstressed and super-strong arrangement. The wishbone is beautifully joined with a TIG weld to the custom machined seat collar of the front triangle. Pure metal artistry.
