yes!
I went from 30 to 28 tire. I'm a big guy at 250 pounds so did not want to go any smaller. Feels more efficient without sacrificing much comfort.

I bought a set of 30mm Specialized All Condition Elite Armadillos, to replace the 28mm Specialized All Condition Elite Armadillos I had on my Sirrus. Felt slower and heavier, so put the 28s back on! The 28s have a max press of 115-125#(recommended), while the 30s max out at 85-95#(recommended) PSI.
Didn't feel any more comfortable, just felt heavier and slower.
I like the 28s on my Sirrus, just like I like the 35s and 40s on my Crosstrail. Now, the 28s and 30s are a no go on the Crosstrail. Really feel harsh.
Completely different bikes, different tires.

Posted this in another thread, but it's relevant here...
UPDATE: Finally made it to my LBS. Rode the Specialized Sirrus Comp Carbon and the Giant Fastroad Comax 1. Both excellent bikes indeed. I liked the "fit and feel" of the Specialized best but liked the upgraded components and the narrower tire size (30mm on Specialized, 25mm on the Giant). For what it's worth, while the Giant had a supposedly "softer" frame (carbon composite vs. full carbon on the Specialized), I thought the Giant had a "stiffer" feel to it. Perhaps is was the narrower tires but I'm not really sure. I ended up ordering the Specialized Sirrus Expert Carbon (in red), which is basically the Sirrus Comp Carbon with the component level of the Giant Fastroad Comax 1. I'll probably have the LBS swap out the 30mm tires for 25's or maybe 28's.
Ordered my wife the Sirrus Vita Comp Carbon (in blue).
My LBS made me great on ordering both. Scheduled for fitting and pickup in a week. Very anxious to start putting some miles on these new rides.
Many thanks for all the comments, insight and recommendations - very much appreciated.

You said later in the thread that those are the plug and play fenders, but to my knowledge the fenders only fit 30mm width tires and your stock bike came with 32mm. Can you provide any insight on this apparent conflict? I've been trying to figure out how wide of a tire I can run with fenders on the Sirrus.
Note that there seems to be a v2 version of the fenders and that is the one that I saw had 30mm requirement. Maybe yours are v1 or something?

Having said that, it's still a $600 bike which is a lot of money. If you're planning on spending more in 12 months have you considered looking for a second hand bike first? Or, depending on how much you ride, you might even get away with a basic $300 bike (new) for the first 12 months?

Does anyone commonly do any of these at medium/high speeds:
-hit heaved sidewalk slabs (2")
-hit roots growing under trails that cause sudden bumps
-ride over lots of sidewalk / road transitions
-ride over 50 feet of grass or slightly bumpy dirt and gravel
What size tires do you have and how does the Sirrus hold up? Do you get flats or damaged wheels? I'm concerned that it may be too much to do an occasional 32 mile round trip commute that features these kinds of problems along the route.

Also, does anyone know if there are any fenders available that fit cleanly on this bike at tire sizes larger than 30? I'm not sure what tire size I'd want, but with a limestone path near me for recreational riding I might need to go bigger than the 30 that the Specialized plug and play fenders can fit. I'm also interested in semi-slick tires for occasional corner cutting on grass between two sidewalks.
I have Sirrus Sport (32mm tire) and plan on mounting SKS 45 fenders.

Great information about the Sirrus.
Has anyone picked the Sirrus after riding a Diverge? I'd be interested in people's thoughts after comparing both and why they went with the Sirrus.

The two bikes, currently (e.g. 2017) are pretty similar: all-rounder disc-braked road bikes with decent tire clearance, one with geometry for flat bars (Sirrus) and one for drops (Diverge).
The '18 Diverge has been redesigned -- with some changes/improvements to my mind -- and I expect the Sirrus will follow, possibly even with the 'future shock' on the top one or two versions, either this year or next.
Choose your preferred bar type -- purchase accordingly. Of the two, I'd go with the Sirrus (my main bike is a 2010) because I prefer flat bars/bar ends for road cycling. If I preferred drops -- Diverge.

2015 Specialized Sirrus Elite Carbon Disc or 2017 Sirrus Sport Carbon
Hi All,
I know nothing about bikes but am interested in getting one for exercise etc. I can get a lightly used 2015 elite carbon disc or a new 2017 sport carbon for a $100 more. Which is the better bike? Thanks.

That's leaving aside any prospective issues arising from buying a used bike (possible frame damage, etc.).

ok thanks, the used is a medium and I assume that is my size as I am 5'9''. I do like the color on the 2015 better. How common/easy is it spray paint parts of a bike like the part that says Specialized in huge letters? I dont like that. I was thinking I can tape off the area

I have the 2016 Sirrus Sport Disk. I has 4800 miles on it now. I have had a slight amount of trouble with the rear shifter ever sine I got it. The LBS has never gotten it shifting exactly right. I am a big guy and have ridden in every sort of Pacific Northwest weather. I've replaced and upgraded the rear dereailleur, crank and now the wheelset. (Rear wheel broke in four places.)

Hydraulic brake issue
Two things where I could use an opinion :
-My LBS (not a Specialized dealer) re-cabled the hydraulic discs on my '16 Elite Carbon. I guess they didn't test ride, as the front (less) and rear (more) brakes squeal like an angry pig , and could be heard from blocks away.
The weird thing is the noise is coming from within the frame itself, and not the rotors. I'll be returning it, but any idea what's going on in case they're stumped?
also,
-I'll be upgrading the wheelset in the offseason. Originally was going to go down from the stock 30's to 28, closer to what I've been riding for decades. But after riding an urban rental with fat tires I was amazed at the ride comfort, and will go up in width, considering our crummy chip/seal roads and the occasional dirt/gravel on my recreational riding. Anyone know the max width for that bike? I'm thinking of 32's-- I've been told I could feel a difference. Also think I'll go tubeless as recommended for lighter weight and fewer punctures.

My '16 Expert Carbon has 32mm tyres. the 35mm Specialized "Plug & Play" fender set also fits so you might be able to fit 35mm tyres in there (without fenders).
Carbon fibre transmits sounds like nothing else - if your pads are making the noise then they're making the noise irrespective of where you can hear it. There's nothing mechanical in the frame itself. Brake pad squeal is usually because the surface between the rear of the pad and the caliper is not seated our lubed properly.

My wife has a 2015 Sirrus Carbon Comp. She has had some ergonomic issues that we have tried to address through a variety of means (swapping out parts, fitting, etc), but she still has some issues.
I am hoping that someone might have some suggestions.
Primarily, she gets back pain when going uphill, and gets hand numbness. (Her hands are comparatively small and a bit weakened from arthritis, and she has hip/back arthritis issues. Age 55).
To address these (and other) issues, I have made the following modifications:
(1) Replaced stock ass-hatchet with B17 woman's saddle
(2) Replaced handlebars with a carbon version (Easton EC70 Handlebar, High-Riser 31.8 720mm, trimmed to 650 mm).
(3) Azonic 420 flat pedals (she won't ride clip-ins)
(4) Replaced Stem with a Ritchey ±30° adjustable stem -- net effect to raise the bars and shorten the reach somewhat
(5) Replaced the 12-30T stock cassette with an 11-36T cassette (and cranked in the B-screw), primarily to make it easier on her back when climbing eg. 10% grades (our flattest local ride is 100ft of climbing per mile).
(6) Optimized positioning of Tektro brake levers -- thinking about replacing with XT for the reach adjustment knob and better braking (I already replaced the rotors with XT).
(7) Swapped out stock tires for ones that are more compliant and comfortable (120 TPI Clement Stradas).
I'm kind of at a loss for what else to try. I feel like I replaced 1/3 of the bike already.

What handgrips are on her bike?
Ergon grips for the win.
She may also benefit from long bar ends that get positioned more in the middle of the handlebar, so that she can grab on to these at times for different hand positions.
You can wrap these bars in handlebar tape, but you may need to go back to an alloy handlebar to make the bar ends able to be tightened.
