Daltex Custom Bicycles

The company is located in Dallas, Texas, United States.

“Nothing is more important to the performance and enjoyment of a quality bicycle that fit. Much like a custom made suit, Daltex bicycle frames are designed and built around your unique body proportions. The materials, tubing diameters, tubing wall thickness, and frame geometry are ‘reverse engineered’ around you and your riding style. This produces a unique bicycle that puts you in the most powerful and comfortable position possible.”

Daltex Road Bike
Daltex Road Bike – “The main frame and fork are designed and manufactured together to achieve a desired result. It is simply a bad idea to put an off the shelf fork on a custom designed bicycle that it was not designed for. If you absolutely must have a carbon fork on your Daltex, let us know early on in the design process. We can integrate your carbon fork’s unique specs into the bicycle design. As you might have guessed, We’d much prefer to design and build the fork along with the frameset.”

DeAnima

Located in Pergine Valsugana, a comune in Trentino, Italy, DeAnima is founded by Gianni Pegoretti, the brother of the legendary framebuilder Dario Pegoretti, Antonio Attanasio and Matt Cazzaniga. Gianni and Dario worked together for nine years, but they parted ways in 2005 and the pair aren’t talking to this day, according to Cyclist magazine.

DeAnima Unblended
This is our second frame in carbon. The first was a prototype, not sold to the the market and served to test bed to arrive at the Unblended. The whole frame is made in Italy, from the original designs for the moulds to produce the tubes, to the actual assembly work. We have our own particular stratification of the carbon fiber layers to produce the tubes, we use a sandwich of Toray T800 3k plain e T800 UD. The joint wrapping required experimentation and tests to arrive at the design we use now. The carbon we use for the wrapping is Toray T700 HM 3K prepreg. To make an Unblended frame the production starts with the tubes being formed in the moulds and being cured. Once the order arrives we start cutting and mitering the tubes to the required size, these are placed into a jig and glued and then wrapped with carbon fiber. This way of building allows us to personalize the geometry based on the client. The frame takes about 2 days to make from start to finish and requires multiple visits to the oven for curing and at various stages. Once the frame is ready for painting it is sanded by hand to remove the surface gloss.100% hand painted finish using custom stencils and hand sprayed using aerograph. Oven and air cured paints. Each frame takes up to 2 days to paint.

“Our motivation is the same as it was at San Patrignano and with my brother Dario: to preserve the old Italian methods of working – the Italian geometry. The cycling business has changed and in Italy we have lost this method. We have only three or four little artisan builders like this now. But the historic brands – Pinarello, De Rosa, partly Colnago – have lost the personal method and embraced the new philosophy of mass production, and for us this is not the soul of framebuilding.”

“Probably our idea is a harder way of doing things, but if I design a bike and then I go to the bank and they give me the money for my business and I put Pegoretti stickers on Chinese frames… this is too simple, and this is not my way of thinking. We will grow and make a small brand with our own idea.” -Gianni Pegoretti

Dekerf Cycle Innovations

Dekerf Cycle Innovations was incorporated in 1991 by Chris DeKerf, the principal framebuilder, and designer whose frames bear his name. The company is located in Richmond, British Columbia, Canada.

“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.”

The results are strikingly beautiful bikes that ride as good as they look. “

DiNucci Cycles

The brand is founded by Mark DiNucci, who started as one of the earliest US framebuilders in the 1970’s. He specialized in handmade frames for road and track and continued that work through the mid 80’s when he turned to designing production bikes for some of the biggest brands in cycling.

“After 25 years of engineering bicycles for other brands I have returned to what I love most, taking the time to design and build frames that reflect my own standards in craftsmanship & performance.”

“Whenever possible, I design every element of your frame, from fit and geometry to tubes, lugs, dropouts and fork crowns. I run a small, one-man shop where every lug is shaped, brazed and filed by me. What I do takes time and only a limited number of DiNucci frames will be made each year. I strive to deliver a frame that is as perfectly crafted as possible and I think the end product is worth the wait.” –Mark DiNucci
