About the Build

After 10 months of riding I’m finally getting around to write about my new bike. There is no shortage of buzz out there on Firefly, a new company started by Tyler Evans, Jamie Medrios along with Kevin Wolfson. I previously worked with these guys when they were with IF – these guys know how to build a bike. It was a fun process for me and interesting to be on the other side of a process I have often led. Kevin designed the frame based on my measurements and turned it over to Jamie and Tyler to work their magic. The frame is built with a Columbus XCr stainless steel tube set, we bead blasted it for a matte finish.  While I am an admitted Campagnolo fan, Shimano’s Di2 has been on my mind. Our shop carries the official certification to work on this gruppo, and what better way to learn the ends and outs?  Many people have told me electronic shifting is the future, my experience with this bike has sealed it for me. This was the first Di2 bike produced by Firefly and they did not disappoint. There are numerous well thought out details from internally routed cables and electronics to a custom battery from Calfee. This battery is lighter, lasts longer, and is considerably more elegant than the stock battery. To complete the frame an ENVE 1.0 carbon fork was custom painted to match the finish of the frame giving the entire bike a consistent aesthetic while not sacrificing road comfort. I finished the bike out with some of my favorite items to spec – Chris King headset, BB, and hubs, Dura-ace pedals, Fizik saddle and tape, Velocity A23 Rims, and Deda Zero 100 bars. I believe in these parts and so I ride them myself.

It was truly a pleasure putting this bike together, and working with Firefly. We love working with customers to achieve the same results. There is no shortage of excellent, competent, mass-produced bikes out there. If you really want to turn some heads when you roll up to Heine Brothers on Sunday morning come in and see what we can do.
