Toray T700 carbon
Hand-laid layup — the same fiber class as superbikes costing 3× more.
Matte Black
SAGS adjustable cockpit
Full fit adjustability around the stem — 140mm of fore/aft pad range and 95mm of stack, no new parts needed.
Mechanical Percision
Shimano's 105 mechanical shifting groupset is both reliable and efficient.
Description
Drop #1: the new SP finishes are here. This build comes in Matte Black as part of our fall color drop. There's one production run, and quantities are limited. Shimano 105 SP builds are not available in other colors.
The SP Shimano 105 is our most popular triathlon bike and the easiest way into true high-performance racing. Triathlete Magazine has named it a Best Beginner Triathlon Bike six times (including this year, 2026). Shimano's 105 mechanical groupset gives you reliable speed and precise shifting without the markup other brands charge.
Built to fit you. The SP was designed with former Cervélo P-Series engineer Kevin Quan. Our Super Adjustable Gooseneck Stem (SAGS) and Super Adjustable Seat Post (SASP) give you more than 140mm of combined adjustment. When Triathlete tested the SP in 2025, their 6'6" tester set up a standard XL to his preferred position with no aftermarket parts. They wrote that "few, if any, other stock models offer so much range."
Heads up: this bike will likely ship in October. Every SP from Drop #1 is hand-assembled by our small team, and some components are ordered on demand for your build. You'll get a shipping confirmation with tracking when your bike leaves. As always, email us if you have any questions!
Please read the full spec before you order. Scroll down to the sizing chart, geometry and build spec to check that the size, finish and components are right for you. Questions? Reach out before you buy and we'll help you choose.
Cosmetic note: the SP 105 comes with black handlebar tape instead of the camo pictured. The chainstay area is fully black, with no red lining.
Ships 92% assembled. You install the seatpost, attach the cockpit and adjust the brakes. It takes about 45 minutes with the included 5nm torque wrench and our step-by-step video on the Bike Setup Page. We also recommend having a 10nm torque wrench. Most local shops will finish the build, or check your fit, for $50–150.
Backed by A2. Your bike ships direct from Portland, Oregon, with a lifetime frame warranty, crash replacement and free size exchanges. You can pay monthly with Affirm, use pre-tax HSA/FSA dollars through Truemed, or get a military and first responder discount through GovX.

Honest comparison
How this build compares
We're a younger brand, so here's an honest, like-for-like look at this build vs the Canyon Speedmax and QR X-PR — matched on groupset and on a carbon wheelset where our build ships carbon (US list, June 2026). Where they beat us, we say so.

Wind Tunnel Tested
Maximized for aerodynamic performance, the SP will help you shave those precious minutes off of race time. Whereas many disc brake bike models test as less aerodynamic than rim brakes, our new SP saved 5 watts compared to its rim brake predecessor.
Front-end Adjustability
The SAG Stem
The A2 SAGS (Super Adjustable Gooseneck) gives you the flexibility to dial in your perfect fit. With our patented spacers and easy integration system, you can set it to 70mm, 90mm, or 110mm, depending on what feels best for your reach in and out of the aero bars.
