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.

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.
