The front end of the Blue is a gorgeous sight to behold, especially when paired with a low-profile brake like this Hooker SL.

More and more, the front end is what defines a tri bike. It's like a signature, and no two are quite the same at the top end of the spectrum. Blue has chosen to employ a bayonet-style fork, an integrated aerobar, aero spacers to increase stack, and a standard front brake. Ultimately, I feel like this is an excellent blend of convenience and aerodynamics. Let's take it from the top down.


The Triad SL uses a proprietary, integrated aerobar-stem combination, and it's a thing of beauty. That's fortunate, because you can't put any other bar on the bike. You're stuck with this one. It comes in five stem lengths from 80mm to 120mm to the armcup bolts, and the pads can adjust 25mm forward or 25mm backwards from there. I rode the 100mm "stem" and kept the pads in the middle position, which gave me the 500mm reach to pad center that I wanted.

The magnificent thing about an integrated bar is how few bolts are on the thing. The entire front end system, including all stem and headset hardware, plus extension and arm cup adjustment hardware, consists of a scant ten bolts. Compare that to the Speed Concept, which uses a staggering twenty-three of them. You can adjust each extension's reach and roll with just a single bolt. It's awesome. And the frontal profile stays wonderfully minimal on account of the integration.

My biggest gripe about this bar is that because the extensions don't come out the back of the bar, you have to trim them to length. That's not a terrible problem, but it's just one more thing to be careful about. And if you decide to change your reach significantly, you can't just swap stems, you'd need a whole new bar. So make sure you know your fit well.

Fork + Brake

The bayonet fork is easy to wrench and adds a lot of stiffness.

The fork on the Triad SL is what's generally referred to as a bayonet-style or external-steerer fork. That means its steerer tube doesn't bear the brunt of your weight, and it's distributed over the outside area of the fork that protrudes from the front. The benefits of this type of fork are that you can make a much narrower profile without compromising stiffness. Blue's implementation of this technique is simple, effective, and very easy to wrench. It uses standard 1-inch bearings on top and bottom, and a standard 1-inch headset, which can all be sourced easily should they ever need replacement. The external section of the fork is bolted down with just a single M6 bolt, while some other systems use two or even three bolts out front. The front end is nice and stiff, yet presents a very svelte profile to the wind.

The only area that Blue didn't bother to integrate is the front brake. The fork uses a standard brake boss, and will accept any standard road brake. That's nice in terms of ease of wrenching, but regular road brakes aren't exactly the most aerodynamic bits out there. Ultimately, using a standard brake on a bike this clean is (in my view) like painting a mustache on the Mona Lisa: it's silly and out-of-place.

So I elected to use a very uncommon brake up front: the legendary Hooker Aero SL. The brake was kindly loaned to me by Heath Dotson of HD Coaching. The Hooker is a very low-profile, center-pull brake, and actually works. Once mounted up, the Blue's frontal profile rivals or beats every other bike out there. There's just nothing to it. Unfortunately, the Hooker is out-of-production, very hard to find, and commands a very high price on the secondary market. The only readily-available center-pull brakes are made by Tektro and TRP (and Campagnolo, which looks like a clone of the Tektro), but it would be nice if someone else started making some other options. In any event, with that little detail in place, the Blue is gorgeous to behold.

But how does it ride? Let's talk about the frameset as a whole, including those aspects.

  • The Blue Triad SL, in all its glory.
  • The Triad SL's bayonet fork is easy to wrench.  Just a single M6 bolt locks it down, and the aero spacers work just like standard spacers on a round fork.
  • The aero spacers are a nice compromise between usability and aerodynamics.  Still, it's generally a good idea to pick a bike that fits you without many spacers, if any.
  • The aerobar is a nice bit of kit indeed.
  • Minimal bolts on the bar: one (or two) for each arm cup, and one for each extension.  Compare that to fourteen bolts for the Speed Concept.
  • The underside of the bar is nice and clean, no junk hanging out.
  • As usual, my first order of business was to slap on my trusty Dash Tri.7 saddle.
  • The rear end is angular and mean-looking.
  • Another shot of the rear cluster.
  • Just a single bolt grabs the extensions - this is a very nice bar to work with.
  • The rear brake cable housing is lined internally, making it SUPER easy to install.
  • The rear derailleur cable is internally-lined as well for easy installation, but you have to order a frame specific to either cabled systems or Di2 - beware if you plan to upgrade in the future.
  • BB30 means just about any crank will fly on this machine, though you may need an adapter.
  • The bike looks great equipped with SRAM Red and a 54-tooth chainring.
  • You can see the large shim in the background - normally this would be trimmed, but Blue asked that I didn't cut the fork down any further, so it stayed on.  The shim itself is what gets compressed by the headset - not the stem - so it was a simple matter to ride slammed without cutting the fork.  That's a nice feature to have if you're still fine-tuning your position.
  • Add on a slim brake like this rare Hooker SL, and the frontal profile is as clean as they come.
  • I was loaning this brake from Heath Dotson of, just for the photos.  It would be nice if there were a more readily-available brake of this kind ... and I think I'm going to look into producing one - stay tuned!
  • It looks lean and mean, and it rides that way too.
  • The Blue Triad SL
  • Another shot of the Hooker SL brake that I borrowed from Heath Dotson of
  • The fork uses a standard 1-inch headset and bearings, so it's easy to find replacement parts if necessary.
  • Blue hides the rear brake beneath the bottom bracket, a move that many manufacturers are doing these days.  This one isn't as sleekly integrated as the brakes on the TM01, Speed Concept, or Felt DA, but this is exactly what Specialized has done with their rear brake for years, and it's worked out well for them.
  • Just a fun little shot I took when dialing in my position on the Blue.  It was a great bike to ride, and I was sad to see it go out the door.
