After finishing up his 16lb Di2 equipped Flash 29er, Andrea seems to have turned his sights toward disc road.The pictures may be a little rough, but don’t let that take away from the bike especially because it’s one of the first we’ve ween with Formula’s RR1 Di2/hydraulic levers outside of Colnago. According to Andrea, this is just a “test” build and “some parts are cheap, others expensive, and others very difficult to find… for a stealth bike.”

Check it out in detail, next.

Likely, what everyone wants to know is how he got a hold of those brakes. We weren’t really aware that you could buy them, perhaps a take off from a Colnago? Eliflap is running the RR1s with 160mm rotors front and rear.

The bike is build on an LTK 027 UD Matte carbon cyclocross frame which Eliflap says is 1100g for the frame, and 400g for the fork. For the crank he is using an Hollowgram SISL2 in 170mm length with Rotor 50-36T oval rings. Xpedo Ti pedals are also included in the mix.

Front and rear derailleurs are standard Dura Ace Di2 7970 units to pair with the Formula RR1 shifters, with internal routing. The battery is also internal which has been modified to fit into the seat tube.Wanting an actual disc brake wheelset, a custom set of brake track-less carbon tubulars was built from Far Sport, China. The rims feature a 24mm profile with no braking track, and are laced with 28 bladed spokes to 100/135mm Novatec MTB hubs front and rear. 23mm Challenge tubulars round out the hoops.

The rest of the bike including the bar, stem, headset, saddle, post, etc. were simply parts he had lying around as his desire to build up the bike and test it was too great to wait. We don’t blame him. Even so, with random parts including a cheap aluminum Syntace bar, the bike comes in at 6740g, or roughly 14.9lbs. Eliflap thinks it should be very easy to get to 6500g and maybe even 6200g (13.67lb).

Thanks again to Eliflap for sending this in. Once again, if you have a cool bike you want to be featured in our Reader’s Rides section, send detailed photos including weight, a complete spec list, and details including anything out of the ordinary to editor@bikerumor. We swear, it doesn’t have to have Di2.
