Firefly :: Recent Works :: Complete Builds

There is nothing more satisfying than seeing it all come together. We have been building quite a few complete custom bicycles here at Firefly and we thought it was about time to take a closer look. We have been posting most of our builds in the Firefly Gallery, but sometimes it’s nice to give a little more explanation…

The first example (pictured above and below) is of a titanium road bike for Ray C. designed primarily for fast dirt road riding. It was built around a great set of tubular tires: 27c FMB Paris Roubaix. Their ability to be run at a lower pressure yet not pinch-flat makes them perfect for their intended use. To accommodate the slightly larger than normal tire we added some room between the chainstays and spec’d longer reach brakes than the standard brakes on this Campagnolo Chorus Gruppo.

This bike also features a compact drive train with gearing suited for steep gravel climbs as well as some anodized graphics (only available on our titanium frames and seatposts) that won’t chip when gravel kicks up into the frame (shred!).


The next full build is of a Stainless Steel road bike made out of Columbus XCR tubing in the Firefly MegaMax profile for Mark N.. The tubing is slightly shaped to take maximum advantage of the tubing’s diameters and wall thicknesses.

The gruppo choice on this bike is Shimano’s top of the line Dura-Ace Di2 electronic shifting system. We ran all of the electronics internally, including the battery, which is installed inside the seatpost. The compact gearing will help Mark on some upcoming rides in the Rockies.

This bike also features a set of hand built wheels with 25mm Michelin tires keep the ride smooth and comfortable. These were made by Justin Spinelli at Luxe Wheelworks. Handmade wheels are always an option for any of our full builds.


The next example is another Columbus XCr frame with Campagnolo Record componentry for Peter O., winner of the first annual Tim Johnson’s Ride On Washington raffle.

We went for a really clean graphic treatment on this one by first polishing then masking off the graphics and glass bead blasting the whole frame. We then peeled off the masking revealing the polished graphics underneath. Peter chose the matte black Mavic Ksyrium SLR wheelset (which comes with special Mavic tires, tubes, and brake pads in one integrated package) to accentuate the subtle and clean aesthetic of the frame.

Another subtle component choice we like is a set of KING waterbottle cages (made in either stainless or titanium), finished to match to the frame.


This titanium road frame for Phil B. sports a brushed finish with glass bead blasted graphics and some brushed titanium KING waterbottle cages. Phil chose Campagnolo Record as the gruppo and a sweet set of ENVE rims laced to some DTSwiss DT240 hubs.

Another detail customers often request is blasting (or in some cases polishing) a person’s name or initials into the frame. Phil’s name was blasted in one of our Knockout fonts.


John B.’s (of the Boston Bicycle School racing team) XCr stainless steel road bike is outfitted with SRAM’s extremely lightweight, top of the line RED gruppo with a Pressfit 30 bottom bracket and another set of the Mavic Ksyrium SLR wheels. The Fizik Arione saddle and FSA Wing Pro Compact bars are John’s favorite and a perfect choice on this bike.

These wheels have an aggressive braking surface that requires the use of the supplied pads. They really have an unrivaled amount of stopping power that must be felt to be believed. That power can be a big asset in the crits and road races for which this bike was designed.


This XCr stainless steel frame for Mike M. features a brushed finish with our surface mount decals. This bike also has a SRAM RED gruppo with a Pressfit 30 bottom bracket and a set of the ENVE rims and DTSwiss DT240 hubs.

We pushed the Firefly graphic treatment a little on this one by asking ENVE for the vector files of their logos and using those files to create some red decals that we inserted into the wheel and fork logos, rounding out the feel of the graphics package.


At first glance you might think: mountain bike. Not so fast. This is a titanium commuter… ish… one might say it is even uncatagorizable, but that’s okay, because it’s custom.

Shirien C.’s bike features a plethora of high end parts from the USA and around the world. A Phil Wood bottom bracket, front and rear belt sprockets, all designed around the use of a Gates belt drive instead of a chain. This bike also uses a 14 speed internal Rohloff Speedhub laced to some ENVE 26″ carbon rims. This results in a broad gear range that runs in almost total silence and never needs to be lubed. The Hope hydraulic disc brake make for incredible stopping power and are easily adjustable for smaller hands (perfect for Shirien).

The custom steel disc fork was handmade by our friend Drew at Engin Cycles just outside of Philadelphia.

    My computer keyboard isn’t going to last very long with me drooling all over it every time y’all post.

    looks as though in the past you have shippedittothacooves!

  4. Tyler, Jamie, and Kevin: seeing y’alls work, and hearing about great bicycles coming out of Firefly, Boston, makes me miss Massachusetts. (mmmm, applefritters)
    I have been working in Portland Oregon for 6 months, and if one thing is for sure there is a saturation of the thing called the bike. People are crazy for them, and they love the masters in the industry. Playland beats.
    Thank you for following your passion, and keeping it real.

    your friend,
