Size Guide

This sizing is how we believe your product should fit for Apparel Only.
If you get advised two sizes, you may either choose the smaller one for an extra racey fit, or the larger one for a more comfortable fit.
Do you prefer a more loose/comfortable fit? Order one size up!
If you're still doubting your size, don't hesitate to contact us via the chat or contact form below.
Always try on your jersey wearing cycling bibs, so as to prevent it looks awkwardly short/tight.

An aero-optimised Frame Module that enhances aerodynamic performance, integrating with your frame to make you faster.

NB: We’ve renamed our frame packs to better reflect bike size. Dimensions are unchanged — what was S/M is now Medium, and L/XL is now Large.

The Aero Frame Module is a performance-oriented solution for competitive gravel racers, developed through rigorous Computational Fluid Dynamics (CFD) analysis to minimise drag within the front of the frame and create a seamless aerodynamic profile, regardless of what you pack.

Combining with the Aero Top Tube Module creates an average 5 watt saving at race speed, validated through wind tunnel testing and race-proven at the highest level, showing a benefit on every bike we’ve tested. View the data.

For years we’ve helped riders go further, now we’re helping them to go faster. Learn how.

– Works with Top Tube Module to improve aerodynamics
– Transfer panel technology reduces drag
– Soft interior base protects contents
– Ultralight Hexagrid construction

Specifications

The Aero System is designed to integrate with your bike to deliver an aerodynamic benefit. As such, the available sizes relate not to the capacity, but to the size of bike that is best suited to deliver this benefit.

We recommend using our Frame Pack Sizing Tool to check the fit before purchase.

As a rough guide, the Small is best matched to bikes from 49-52cm, the Medium is best matched to bikes from 52-56cm, the Large size is best suited to bikes sized 56-58cm and above.
