100% adjustable, aero and affordable. The SP has it all. We worked closely with Kevin Quan Studios to develop the SP to fit you, and not the other way around. From the SAG Stem to the SA Seat Post, you can find any position imaginable.  

Shimano Ultegra Mechanical is Shimano’s second-highest performance groupset and features upgrades such as lighter weight and more precise shifting. Functionally, it performs with Shimano’s top-tier components but maintains a more affordable price based on materials. This is an excellent choice for athletes who want top shifting performance but aren’t ready or interested in electronic shifting. 

Mechanical disc brakes means both cost savings and easy adjustments at home without the need for specialized hydraulic tools. Finally, the Vision TriMax alloy cockpit keeps you aero and race-ready without breaking the bank, meaning that you can focus on racing more. 

5nm torque wrench included in your order for bike setup. We highly recommend taking your bike to your local bike shop to finish setup especially if you have ordered Di2 or need any assistance in the final steps of setup. For more information on how to set up your SP, head to our SP setup page.

As fast as anything

Whether you’re racing to win or racing to reach finish lines, A2 bikes are designed to perform at the highest level. Our A2 athletes have stood on pro podiums, broken records, and chased olympic dreams. High quality, high performance, high value – you can have it all with the SP. 

Crafted with intention

We understand that triathlon bikes don’t just need to be as aero as possible; they also need to fit you and your race needs. Enter: the Super Adjustable Gooseneck Stem (SAGS) and the Super Adjustable Seat Post (SASP) –  all unique to A2 Bikes and ready for your next fit. 

Wind tunnel tested

Our upgraded disc brake SP was designed to break the mold – 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. 

Maximize storage with multiple attachment options to keep your nutrition on point for everything from training rides to IRONMAN.

Adjustable components to maximize your perfect position with the debut of our A2 SAG stem and SA seat post (SASP).

Disc brakes to keep you safe and able to stop when you need to

Maximum adjustability allows you to modify your position forward and back up to 140mm, and to raise your cockpit with the advantage of stem spacers and a positive rise right "out of the box"
