Specialized Sirrus 2011 Hybrid Bike

Specialized Sirrus Overview

The Specialized Sirrus is a hybrid bike that can cope with as many uses as possible. It need not be tied down to one specific style of cycling so it will be just as happy trekking hundreds of miles on a long distance jaunt as it will being used to head to the newsagents for the paper and a pint of milk. Despite this diversity it does not lack focus and provides comfort and consistency no matter where it is used.

You will be able to fly past car owners and deftly control the Specialized Sirrus as you blast through traffic thanks to its premium aluminium frame, steel fork and sporty tyres. Its clever frame geometry and rigid set up means that it can quickly accelerate when the need arises but it also has comfort at its heart with an inviting saddle and appropriate handlebar set up.

Specialized has chosen to go with a simple look for the Sirrus and its black paint job is workmanlike without being boring. What you do get is a fine degree of workmanship, which belies the relatively low price for which this is being made available. It is part of a competitive segment of the market and has a lot to prove, but judged individually, it is easy to recommend.
