Specialized has launched the new Sirrus Carbon, a premium hybrid bike that dispenses with the lower half of the seat tube in a radical 1x-specific design said to improve comfort.<\/p>\n

In a design similar to that we saw from the prototype Rondo Ruut gravel bike<\/a>, the Sirrus Carbon\u2019s dropped seatstays join midway down the seat tube.<\/p>\n

However, instead of the seat tube then continuing to the bottom bracket, it splits off to join the down tube.<\/p>\n

Specialized calls this design a Compliance Junction and says \u201cit\u2019s been designed to have just the right amount of flex and forgiveness across the carbon frame without sacrificing performance and efficiency\u201d.<\/p>\n

There are two bikes in the range at launch, the Sirrus 6.0 priced at \u00a32,400 \/ $3,000, and the Sirrus X 5.0 priced at \u00a31,950 \/ $2,250.<\/p>\n
