Earlier this year Specialized released a patent for a new frame design which incorporated a ‘strut brace’ and saw the removal of a lower section of the frame's seat tube. The radical design, said Specialized, resulted in improved comfort with no compromise in ride quality.
We weren't sure that this new design would make it to market but did speculate that if it did it'd be on a gravel or endurance bike, potentially adding itself to the pantheon of revolutionary road racing bikes. We were wrong on both counts, as this highly distinctive frame is here and it's in the shape of the all-new Sirrus Carbon - the update of the brand's flat bar fitness and commuting favourite.
