Thanks for the replies and the dialogue regarding our bikes. The Balcom frame was indeed designed and engineered in house, and we do own the molds. While our bike may have some visual similarities to others in the market place, it is not the same frame. If you look at the detail photos of our bike, you may be able to quickly spot some of the differences.
We do indeed have two different fits. We offer a Race fit with shorter head tubes, and an Endurance fit with a longer head tube for a more upright riding position. Since we don't recommend more than 40mm of stack on a steerer above the top of the head tube, this type of versatility is critical in being able to properly fit most cyclists. For those that aren't sure of which size fits them best, we also include a bike fit using the Retul 3D motion capture fitting system on a size cycle to determine a rider's handlebar stack and reach numbers and then recommend a size and fit based on the results of the fitting. The price of the fit is included in the complete price of the bike.
From a bike fit perspective, a smaller frame is not an ideal way to achieve a race fit. Achieving a true race fit would traditionally be to allow the rider to run a smaller back angle, while maintaining a proper armpit angle to their wrist. While this can sometimes be achieved with a smaller race frame, one then runs the risk of placing the rider to far over the pedal spindle with the steeper seat angles of the smaller frames, or also causing back problems with a lower back angle but with a reach that is to short to the hoods or drops. This could cause back issues while riding under power (even with a very long stem).
Ideally, a rider would just be able to get lower on the correct size frame. Which is why so many Pro Tour teams run frames with custom geometries, often running head tubes 15-30mm lower than what can be bought by consumers. We're doing our best to bring this type of selection and fit to our customers with our bikes.
