Get to know the SP 105
The SP Shimano 105 is our flagship triathlon bike and our most popular model for a reason. Offering the lowest barrier of entry into true high-performance triathlon riding, the SP 105 delivers everything you need to dominate the bike leg without the industry-standard markup.
Built with Shimano’s trusted 105 mechanical groupset, this model is perfect for athletes who want reliable speed and precision shifting without paying the premium prices other brands demand.
Designed in collaboration with former Cervélo P-Series engineer Kevin Quan, the SP was engineered with one goal: to fit you. With a highly adjustable stem and seatpost, the SP accommodates a wide range of rider positions, ensuring you can dial in your ideal triathlon setup.
Every order includes a 5nm torque wrench to assist with initial assembly; however, we highly recommend having a 10nm torque wrench already. Also, we strongly recommend taking your bike to a local bike shop for final setup, especially if you’d like assistance perfecting your fit. For step-by-step setup guidance, visit our Bike Setup Page.
