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.

A strapless, aero-optimised top tube pack that integrates seamlessly on your bike to make you faster.

The Aero Bolt-On Top Tube Module is a performance-oriented solution for competitive gravel racers, developed through rigorous Computational Fluid Dynamics (CFD) analysis to smooth airflow behind the stem and improve aerodynamic efficiency.

Combining  with the Aero Frame 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 Frame Module to improve aerodynamics
– Transfer panel technology reduces drag
– One-handed fast entry to top tube module
– Ultralight Hexagrid construction

Materials & Technology

HEXAGRID
An ultralight, high strength nylon grid, laminated with TPU to create a minimalist yet structured material. PFAs and PFC-free.

HDPE
High strength and rigidity reinforcement boarding with good shape recall to avoid deformation.

AERO OPTIMISED
Active improvement of the aerodynamic performance of the bike and rider.

ULTRALIGHT
Minimal design & lightweight materials for optimal weight-performance.
