Felt's B2 is a fantastic bike. It takes the very best of Felt's aerodynamic prowess and fits it into a traditional, non-proprietary package that lets you install pretty much any kind of components you like. This build represents the way I like this bike. The final result is a race-worthy machine that could easily best a lot of so-called 'superbikes' without resorting to a single integrated part or proprietary interface. Have a look at the article for our in-depth review of the frame. And the gallery below has some additional detail in the image captions. Enjoy!

Complete Bike 

  • This is the Felt B2, built up TriRig style.
  • The B2, from straight on. Obviously there's not a lot to see here.
  • A little closer up, you can see that the cables are managed quite well by the Alpha and Sigma, going straight into the B2's top tube cable ports.
  • From behind the stem, you can see exactly how the cables are managed.
  • Another hindquarters shot of the B2.
  • I love how this bike looks from just about every angle.
  • The Ultegra Di2 drivetrain shifts perfectly. I put the Dura-Ace crank on for the extra bling factor, and because I like it so much. In this show you can see the B2's battery cover, originally developed for the DA.
  • My trusty Dash Stage.9 saddle on the B2's forward-offset seatpost, standard issue with every frame. I also have a rear-facing bottle cage zip-tied to the Dash saddle.
  • The TriRig Alpha with Gamma extensions keeps everything clean up front.
  • The B2 quite easily passes the 'eyeball wind tunnel test,' given how clean everything is throughout the bike.
  • If there's any reason not to love this setup, I don't know what it is.
  • The Felt B2 with a TriRig Alpha, Sigma, and Omega front end. Here I'm also using the Felt F-bend extensions, but elsewhere in the article swapped them out for TriRig Gamma extensions.
  • Here you can see how the Sigma manages the cables going into the B2 top tube, while still keeping the Di2 junction accessible. From this angle, it looks like a lot of cabling, but from the front, the wind sees none of it.
  • The TriRig Omega is a perfect fit for the frontal profile of the B2's fork.
  • Another shot of that gorgeous Di2 drivetrain.
  • TriRig Mercury pedals, for good measure.
  • Another closeup of the Dash Stage.9 saddle.
  • I'm not a huge fan of the two-bolt bottom-address saddle clamp, but it works just fine.
  • The BTA cage works perfectly. I have it affixed to a prototype BTA mount for the Alpha aerobar, which will get some attention in a future article.
  • The Profile Design HC Bottle is my weapon of choice for the BTA cage.
  • Viewed from the front, the Profile Design HC Bottle is a beautiful addition to the bike.
  • Here's the Omega SV mounted below the bottom bracket on the Felt B2.
  • The Omega SV is a great replacement for the much less attractive TRP brake, in my rather biased opinion.
  • The Omega SV fully installed, tucked up under the bottom bracket. All the bolts remain accessible, even with the crank in place

Bayonet 3 Bar, TTR2 Wheels 

  • Felt's Bayonet 3 Aerobar is a really good value bar, offering a lot of adjustment for a very low price.
  • The Bayonet 3 doesn't have the lowest frontal area, but it's very good for a budget aluminum bar.

  • More details of the Bayonet 3 aerobar system. Sadly, it takes a whopping EIGHTEEN BOLTS to fully assemble the system, and a large number of tiny washers that nest between the components.

  • The TTR2 wheels offer very good (if slightly old) aerodynamic design at a low-budget price point.
  • Felt's TTR2 rims use the hybrid toroidal design seen on Zipp's previous-generation wheelsets.
  • Narrow hubs on the TTR2 front wheel keeps the spokes out of the wind.
