Guest blog from Mr. Dave Roth and his first few months with his Signal Pulse.

Towards the end of 2013, I decided to sell my carbon race machine. I had spent the previous six months riding and racing this amazing bike - it was super light, responsive and the blacked-out color scheme looked badass. That said, I wasn’t 100% stoked with the build kit and, being from a major manufacturer, the frame geometry made a couple of compromises that didn’t quite fit me or my riding style. 

At the time, I was planning on squirreling away the proceeds from this sale for a new road machine at the beginning of 2014, but had not made any decisions as to what it would be. An afternoon cup of coffee with Nate in October turned out to be the initial spark for the Signal Pulse project and the bike I’m writing about today.

That cup of coffee began a number of conversations over the phone and through email discussing tubesets, ideal geometry for an aggressive race-worthy bike, paint schemes and color options, and a number of other details along the way. Seeing my opinions and feedback realized in the various design iterations along the way was really fun and I’m honored that Signal invited me along for the ride.

Without geeking out too much, I wanted to discuss how my desired ride characteristics were achieved through frame materials and geometry. Coming from a road racing background, I wanted a bike that was stiff, quick-handling, relatively light, and comfortable on long rides. Going into this project, I knew I wasn’t going to end up with a 15lb bike and I decided early on that I was okay with that. More importantly, I wanted a bike that could be ridden five hours, without beating the shit out of me and one that could confidently rail the corners on big mountain descents with no steering wobble. I also wanted a bike that could be pushed hard into corners without hesitation in a local crit.

To meet these criteria, Signal used a TIG welded “double” oversized Columbus tubeset with a tapered head tube matched to a tapered Enve Carbon fork. Combined, these materials result in a stiff, yet comfortable package. Highlights of the frame geometry include a 73 degree seat angle and a 73.5 degree head angle. Chainstays are a tight 408mm with a top tube length of 57.5cm and a head tube length of 150mm. Combined, these fit my 6’ height and riding style very well.

Other details on my bike include a braze-on front derailleur mount, Paragon “Breezer” style dropouts with replaceable hanger, and built-in barrel adjusters for on-the-fly shift adjustments. A standard threaded bottom bracket was used because it’s simple and proven. Finishing the frame is a beautiful three color paint job by Spectrum out of Colorado. I built the bike up with a mechanical Dura Ace 9000 group and Thomson bar, stem and post.

Having now ridden the bike for about a month, I can honestly say that my expectations were beyond met. The Signal Pulse accomplishes everything I want and need out of a road bike and it does it with style. It’s not the lightest or most technically advanced bike out there, but it’s one with a story and some history that I’m excited to be part of. It’s a bike that I plan on riding for many years to come.
