Biking Hawk Hill with my epic new Specialized Sirrus Comp Disc bike!

After many months of research I decided to go with the epic 2015 Specialized Sirrus Comp Disc bike!! It is a "city" or "fitness" bike, and I've also seen it referred to as "flat bar road" bike. It is totally awesome and I am already loving it.

Sweet ride, bro
Uggggh it is soooo aweeesooome.

The weight of the bike is really light and it's really fast. The 700cc x 30 tires have an incredible amount of "pick up" compared to my old mountain bike. I am really happy with how fast it can accelerate, and also how it can crush the San Francisco hills. The 2 x 10 gears are working out well so far, even for some crazy hills.

Here are the specs!
The Sirrus Comp Disc with Fitness Geometry provides flat bar handling so you can ride faster on longer rides, yet be stable and quick in town. The hydraulic disc brakes mean you'll have confidence to ride regardless of the weather or what you're carrying on your racks.
  • New E5 Premium Aluminum frame w/ Fitness Geometry built for speed and versatility
  • FACT carbon fork w/ Zertz provides lightweight and smooth handling
  • Specialized Espoir Sport Reflect, 700x30c tires for performance and visibility
  • Specialized Body Geometry Targa, lock-on grips w/ integrated bar end for no-slip performance
  • Tektro Gemini, hydraulic disc brakes for maximum stopping power
  • Shimano Tiagra, 10-speed derailleur for plenty of gearing options
  • Body Geometry Targa Sport saddle w/ steel rails for all conditions comfort
  • Compatible with Specialized Plug + Play Fender Set

So yes, this is amazing.

To really give this a test, I decided to go with my buddy Alex over the Golden Gate Bridge and all the way up Hawk Hill in the Marin Headlands which is a big climb. Even crazier, we decided to go DOWN the other side of Hawk Hill which is one-way, but super steep. As these were brand new brakes I took it slowly, but in the video you'll see Alex just flooring it down the hill. :)

At the top of Hawk Hill
I could have never done that ride before on my 26'er mountain bike. This bike really allows me to do harder, steeper, longer rides like this one. I wasn't sure if it could handle this as well as a road bike, but I found it really did. Super awesome bike. After the long ride, we stopped in Sausalito for ice cream, obv.

A very important part of the ride
The other cool part of the ride is Alex was testing out his new gimbal stabilizer for his new GoPro camera. It makes for some really smooth video (and you can really see the difference when you compare the video from Alex's bike with the video from the GoPro mounted to my helmet). The stabilized footage looks amazing. Check out an edited clip of some of the bike highlights here!

Congrats for your bike ! I hope you still enjoy it !
I own mine since sept.2013 and have ridden 9000 km, touring and commuting.
It's a 2014 "Comp" model, with carbon fork, rim brakes and an all-SRAM X7 front and rear transmission.
I swapped the stock pedals for "double function" shimano models (flat<>spd); bought a new saddle and a pair of SKS mudguards for bad winter days.
It's a fantastic bike, fast and comfortable, and I often get nice comments about its look.
The stock tyres were the same as yours (Spe espoir sport) but 700x28. IMO, it's the weakest part of the bike, despite their puncture resistance and the good mileage I got from them. Their 60 tpi casing is a bit harsh to my taste. They've been replaced by a pair of 150 tpi casing Vittoria Rubino Pros (still in 700x28), which are lighter and smoother and give a far better ride.
Axis 1.0 wheels are not amongst the lightest on the market, but they're sturdy, good looking and still amazingly true (roads are bad, here in Belgium). Their freewheel is very quiet too !
Have fun with your Sirrus !

How are you finding the Sirrus 5months on? I've been looking into buying one to replace the 2012 Sirrus Elite that got totalled in an accident, but the bend in the top frame has me a little lery over the longevity of the frame as I'd imagine its a weak point.

Their particular 58 tpi covering can be a tad tough to be able to my own style. They are swapped out simply by a couple of one hundred fifty tpi covering Vittoria Rubino Advantages (nonetheless inside 700x28), which can be light and also simpler and present any greater
