Description
Our FWS tubeless compatible clinchers have efficient low drag profiles optimized for use with 23mm to 26mm tyres which deliver excellent aerodynamic performance in real world conditions. Intended primarily for use in TT and Triathlon, these deep rim wheelsets display excellent handling characteristics which would also permit use in road racing or fast training sessions.
A wide 19mm inner rim bed improves tyre to rim interface when using recommended tyre sizes keeping airflow disruption to a minimum. Increased tyre volume enhances comfort and control while reducing the potential for pinch flats if running with inner tubes as the tyre sits inline with the outer rim.
Manufactured using FWS technology results in an evenly balanced, lighter, stiffer rim which is handbuilt onto DT Swiss hubs using Sapim CX Ray spokes to produce a high quality Pro level performance wheelset.
TYRE RECOMMENDATION
A highly versatile rim design allows a great general aerodynamic compatibility using a tyre width
ranging from 23mm to 26mm. Due to the wide inner rim track inflated tyres will sit between
1mm to 2mm wider than indicated depending on tyre brand.
Wider tyres can be supported up to 45mm but will inevitably come with an aerodynamic penalty.
MAXIMUM RECOMMENDED TYRE PRESSURE
23mm – 90psi / 6.2bar
25mm – 80psi / 5.5bar
28mm – 70psi / 4.8
