Loose bearings on Sirrus x 3.0 and 4.0 . Aluminum frames too. Broke my carbon Sirrus frame last year after a collision. I would recommend better components and light aluminum on the Quick 1.

Winter Upgrades!
After researching wheels/tires most of the winter I "settled" on a set of GRX wheels, and Conti Terra Speeds. The GRX wheelset seems like a really good value and decent weight savings from the stock setup. I couldn't justify 2x more $$ to save a few hundred grams from where the GRX is positioned. The Terra Speeds initially were measuring at 38, but after a few weeks now, both are just a touch under 40mm at 40psi. Everything setup tubeless super easy, I ended up using 2oz of Orange Seal per wheel. I haven't logged too many miles yet due to work and weather, but what I have has been nice. The tires roll fast and are quite comfortable.

I'm looking at the Roval 24s (I think that's the number). Pretty decent: under 1600 or so grams/set, aluminum rims (no interest in carbon), DT Swiss internals. Would be nice to get shot of the boat anchor stock wheels -- among other things, I don't like the faux 'aero' deep section rims. A nice sensible box-section rim will do me just fine.

I’ve been considering getting the Diverge but I really prefer flat bars and would hate buying that bike and immediately dropping more cash to convert the bars. I do like that the Diverge has a higher gearing though and more speed always appeals to me lol. Is that the main difference between the Sirrus and diverge aside from the handlebars?

Essentially, Specialized has rationalized the Sirrus line into two series. The 'regular' ones (e.g. Sirrus 6.0) align more with the Roubaix (endurance/road), the X ones (e.g. Sirrus X 5.0) align more with the Diverge (road/'gravel'). The former have more 'road-like' 2x gearing; the latter have 1x gearing and 'gravel' tires.
Tires and gearing are easy to change, so other than being sure you want a 1x drivetrain there's not much in it.
However, my advice would be to be sure you want either drop or flat bars before choosing. The current Sirrus geometry is optimized for flat bars -- rightly so -- so they won't convert 'properly' to drops, in my opinion, and that's leaving aside the expense. The converse is also true: you could convert a Roubaix/Diverge to flats, but why bother when optimized versions are available?
That's my take, fwiw.

Thanks for the replies! You were right about it being easier to upgrade the Sirrus components versus buying the more expensive diverge and then changing everything on that. One thing I really like about the diverge is the clearance and room it has for a wide variety of tire sizes and the ability to get some big tires on there. How much more in the options for bigger tires does the diverge have to the Sirrus. Aside from that in all of the components is the frame geometry that much different?

Unfortunately, I do not have a scale to measure all my upgrades.
Badger is right, my hooptie has the first gen FS nothing new there all stock.

I do like them so far, but have yet to get more than a few quick rides on the wheelset. I really couldn't justify the Roval's at $800, even looked into a custom wheel build. I got a screaming deal on the GRXs NIB on ebay.
Yes Saint Icetech's, I summarized all the brake upgrade in post 902.

I am considering investing in some cargo racks and bags for my Sirrus. Does anybody have experience with their own bikes? What systems work best for you? I am planning a one week trip on the GAP/C&O Canal trail from DC to Pittsburgh.

Thought I’d throw a photo of my 2019 Sirrus Sport up. As a runner I needed to add more training volume without increasing the pounding on my body. Plus running in the Florida heat and humidity sucks.
Upgrades from stock are:
Ergon GP3 grips
Shimano SPD SL Pedals
Sora Crankset
WTB Silverado Saddle
Continental GP 4 Season Tires 28mm
Changing saddle and tires made a huge difference. I liked the bike before but I love it now. May decide to upgrade the wheels eventually if I can find something that isn’t too expensive.

2020 Sirrus Expert Carbon VS 2019 Sirrus Elite Carbon
What are the differences? I’m stepping out of entry level bikes and moving into my first carbon. I know some stuff but not all hoping you all can provide some help. Does the Elite Carbon include the “Future shock”?

It does not, nor does its successor the Sirrus 4.0 (carbon). Have to go up to the Sirrus Expert (now the Sirrus 6.0) to get FS on the bike with a 2x drivetrain. The Sirrus X (Comp; now called 5.0) does have FS, but it is a 1x drivetrain.

Hi -hope this is right place to ask.. sorry newbie here... i have have a 2012 or 2013 basic specialized sirrus hybrid. The bottom bracket is worn and knocking, its all standard bits as i bought the bike from new. Does anyone know what dimension bottom bracket is required before i take it apart? or where i can look to find out? any help appreciated. thank you.

For square taper BBs, the one to get now is the BBUN55 - the spindle is hollow for lower weight.

I have the Sirrus X Comp carbon (same bike, 2019), and swapped out the tires for Spec. Roubaix Pro 32 road tires ... simply my preference. Made the bike into exactly what I was looking for.
The only thing with the X carbon: be sure you want a 1x drivetrain -- it's a dedicated 1x version of the frameset.
