Ribble's lightweight race road bike. Low stack/reach for a D2C British brand, the climbing sibling to Ultra aero.
Racers and fit riders who want Giant's race geometry without Propel's deep tubes.
Giant's lightweight race bike: compact sloping top tube, sharp steering, and a fit that has been a stack/reach reference for a long time. Less aero drama than Propel.
Racers who like Cannondale's handling and want the serviceable frame. Synapse is the taller sibling; SuperX is the CX/gravel race cousin.
The fourth-generation EVO keeps the third generation's geometry but goes lighter, slipperier, and back to a threaded BSA bottom bracket. Same fit as the 2020–2022 bike, easier to live with.
Racers and fast club riders who want the modern Tarmac. If you came off an SL7, check that the stack/reach still matches your size.
The current Specialized race bike: lighter than SL7, still aero, and famously 'it just disappears' if the fit is right. Size by stack/reach — the 54/56 split is where a lot of riders hop.
