The new Strattos Disc brakes series offers an all-rounder road bikes to inspire you to turn every inch of pedal movement into pure speed. With technical parameters surpassing UCI standards and regulations, featuring a geometry favoured by riders who have powerful pedalling style and also equipped with disc brakes for powerful and fade-free braking in all conditions. These agile carbon and alloy road bikes are made to fulfil your need for maximum performance either on your local lunch ride or when sprinting for the podium.

The new S8 Disc is built around an upgraded ACX Carbon Performance frame built from Toray T-700 and high-modulus carbon fiber. The design upgrades see the Strattos frame take on a more aero persona with truncated aero tube profiles, together with a new integrated seat clamp junction. The seat tube stops at the junction of the top tube rather than extending upwards with the seat post, this certainly results in marginal aero gains but it also gives the bike much cleaner lines. This is further extenuated with the seat clamp which is integrated into the tube shapes.

New Ultegra R8000 series is “pro-proven” as it is a direct trickle down from Dura-Ace groupset. As road bike component, the stress-free operation is one of the most important features to lead all-day riding comfort with braking and shifting. The Shimano Ultegra R8020 series shifters bring greater rider control in all conditions thanks to SHIMANO’s category-leading hydraulic disc brakes. Lighter front shift action and refined ergonomic shape sweeten the deal.

You will notice the upfront torsional stiffness of this frame, created with the tapered headtube. This provides exceptional handling during descents and sprints. This is complemented with the beefy Shimano press-fit BB86 bottom bracket. This wider bottom bracket shell anchors the oversized drive spine, solidly transferring power to the drivetrain while reducing watt-sucking lateral movement.

It’s the broad notes of comfort that really lingers with the rider, however, with the narrower, flat-section seat stays absorbing any jarring road noise. Furthermore, the fork with tapered steerer, has carbon layered in a specific way to ensure that there is a level of vertical compliance whilst still maintaining that ever important, horizontal rigidity.

The S8 rolls on a set of lightweight Entity XL3 tubeless ready wheels with sealed bearing hubs. Completing the bike is lightweight, hydroformed and butted Entity Xpert components including short drop handlebar, stem, seatpost and saddle.
