Product Description


Specialized Sirrus Sport 2018

The Sport version of the Sirrus is upgraded with a carbon fork, Tektro hydraulic disc brakes, neater 2x9 microSHIFT gear shifters and a Shimano Sora rear mech.

Upgrades over Specialized Sirrus Disc

  • Specialized FACT (Functionally Advanced Composite Technology) carbon fork
  • If you want to reduce weight whilst improving comfort, aerodynamics and steering response, upgrading the fork blades from metal to carbon is probably the most profound improvement you can make on a flatbar road bike
  • Through-axle front wheel - the 12mm through-axle borrows from proven mountain bike technology to create a stiffer, stronger and more secure interface between front wheel and fork without compromising its tool-free quick-release utility
  • Spec'd on literally thousands of mountain bikes and hybrids, Tektro hydraulic disc brakes are the best proven stoppers at this price point
  • Why you should consider a bike with high quality hydraulic disc brakes - visit our blog
  • microSHIFT 2x9 gear shifters are especially neat and especially smooth action
  • The 2x9 shifters with 32/48 chainrings and 11-34 cassette offer a similar range of gears as a 3x8 drivetrain, but in a simplified format

Same as Specialized Sirrus Disc

  • Like every Sirrus, this bike benefits from its heritage of being, probably, the best-proven flatbar road bike design
  • What is a flatbar road bike - see our blog
  • Its confidence-inspiring perfectly aligned Specialized A1 premium aluminum frame will be among the lightest at its price point
  • Internal gear cable routing makes for a cleaner finish that accentuates the frame's gorgeous paint job
  • The flat-disc brake mounts are much neater and lighter weight than first-generation disc brake frame bosses
  • Rack and mudguards mounts
  • Free fitting - order any extras such as mudguards with the bike and we will waive our standard fitting charge
  • Fitness Geometry (73.5 degree seat tube / 71 degree head tube angles in medium size) makes for a bike that combines speed potential with stability and rider comfort
  • The flatbar controls (i.e. the brake levers and the shifters) will be familiar to just about anyone who has ridden a mountain bike
  • The Sirrus rolls on 700x32 tyres from one of the world's most respected bicycle tyre companies - Specialized
  • Specialized Nimbus all-rounder 700x32 tyres are fast but forgiving, and feature reflective sidewalls and Flak Jacket puncture protection

Here's how Specialized describe the Sirrus Sport
As you push yourself towards your fitness goals, you need a partner that you can count on, and we're happy to say that the Sirrus Sport fits the bill.

It's constructed from a durable, reliable, and lightweight A1 SL Premium Aluminium, and it features a bombproof assortment of components, like a Shimano Sora rear derailleur and powerful Tektro hydraulic disc brakes that are sure to get the job done.

Sprinkle in some added comfort from our proven Body Geometry components, like the grips and saddle, and a Fitness geometry that lives in the sweet spot between comfort and performance, and you have a bike that'll always be ready to go when it comes time to sweat.

  • Working with our Body Geometry team, we designed a frame that strikes the optimal balance between comfort and efficiency.
  • The A1SL Premium Aluminium construction pairs weight savings with rugged durability, while the rack, fender, and disc mounts give you an incredibly versatile package.
  • The lightweight FACT carbon fibre fork provides a smooth, responsive ride, while the Plug + Play fender mounts give you the option to install rain-fighting fenders.
  • Braking duties are handled by Tektro hydraulic disc brakes to ensure effective, consistent, and reliable power through any kind of terrain or condition.
