When speed is all that matters the Assos CS.speedfireChronosuit s7 Speed Suit is your weapon of choice. Cut for the aggressive positions of TT bikes the low neck, narrow shoulders and insert position make for minimum air resistance and maximum comfort.

With a specific focus on speed Assos have chosen a material tested and refined in the wind tunnel to maximise a clean airflow, thus making you faster. Further aerodynamic features include the bonded elastic zip and low neck to improve fit when in a low position, plus raw cut edges to reduce seams which in turn reduces drag. 

It's not just about speed, comfort has to be a consideration too - it's no good being fast if you can't remain comfortable. To this end the industry-leading S7 seat insert is used. Offering unrivalled support and comfort, Assos have also carefully placed it slightly further forward than normal as this suits the low and more aggressive TT position you'll be riding in. 

This isn't your everyday bit of kit -  grab it when every watt saved through aerodynamics is vital and could get you the win - whether that's a club 10, national champs or you're Fabian Cancellara winning Gold!

About the Assos brand

Assos are one of the world's pioneers and specialists in producing high quality cycling clothes and accessories. They are located in a region of Switzerland that has maintained a long standing tradition in first class textile engineering. In the 1970's, Toni Maier-Moussa, founder and chairman of Assos accidently invented lycra cycling clothing, whilst trying to create the ultimate bicycle. During the wind tunnel tests of the first ever carbon-fibre bike, Toni inadvertently found that lycra downhill ski racing suits had much less drag than the woolen-knitted cycling clothes of the time. To this day Assos firmly believe in total product competence, delivering optimum function and comfort, by researching and making its cycling clothing and accessories from the very best materials.
