Performance matters, and you want our highest-level carbon lay-up, tubeless carbon wheels and the customisable shifts of Shimano Ultegra Di2.

The tech you get

An insanely light frame made of our highest-level 900 Series OCLV Carbon with aero tubing and IsoFlow comfort technology, and RSL Aero Bottles and Cages that save watts. A 2x12 Shimano Ultegra Di2 group set for lightning-fast shifting that's completely customisable. A universal derailleur hanger so you can get a replacement from anywhere. Plus, it's topped off with Bontrager Aeolus Pro 51 tubeless carbon wheels and a Trek Aero RSL one-piece bar/stem.

The final word

Sizing

How tall are you?

To measure your height, stand up straight, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.

What is your inside leg?

How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inside leg measurement. Your inside leg is very important to your final bike size so please measure carefully.
