I cut these down to 710mm (28in). The stock bars felt way too narrow for me. I'm used to riding with bars in the 740-780mm range on my mountain bikes. I'll be using this bike primarily for commuting and errands, so I wanted a length that offered more stability and control compared to narrow bars.

Took it out for a spin this weekend to try out the new tires. It's amazing how much easier this bike is going up hills. I cut 45 seconds off of the hilly area segment of my normal ride and that was with me having to slow down to figure out why my bottle was leaking water all over my leg (it helps when you tighten down the cap apparently). I still have some fine tuning I need to do position wise on the bike but overall I'm pretty damn happy with this thing!

Did you end up going with the GP4000s tires? I'd like to get rid of the stock tires as well. I've got 28c GP4000s on my road bike, and they are excellent. I'd like to stick with 30c-32c on this bike. I may wait until I get new wheels and set it up tubeless with either the Schwalbe Pro Ones or the Specialized Roubaix 2Bliss....choices, choices choices!

I went with the Vittoria Open Pave EVO CG III in a strange 27mm size. Reviews made it sound great on roads and trails thanks to a softer sidewall and I agree. It's a substantially nicer riding tire. It rolls great too!

I'm thinking of putting Schwalbe Winter Marathon studded tires on my 2016 Sirrus Pro Carbon to handle the ice patches on our city pathways. I know that the lower end carbon models came with 700x30 tires and I remember at the time looking at them and thinking that a 35 would probably fit. My bike came with 26/28 on it so 35 will be quite a jump but the frames/forks are all the same so I'm hoping that 35 fits. Has anyone put 35's on a similar Carbon Sirrus?

AVLThumper

My 2017 Carbon came with 700x30 Specialized Espoir. I am also interested in knowing if a 35c would fit. My not so professional at home measurements lead me to believe it would work just fine. If you give it a try, please post up and let us know.

I went to my LBS and they happened to have a good selection of Schwalbe Marathon studded tires in stock so we grabbed a Sirrus Pro Carbon and tried some sizes. 35c definitely do not fit. Maybe some 35c tires would fit, but the Marathon has a bit of a knobbier tread. It definitely looks like there is enough width between the chainstays for a 35c but the issue is more the shape of the "yoke" area at the bottom bracket where the chainstays come together. The wheel also has to push forward towards the bottom bracket a bit before settling rearward into the dropouts.

We then tried a 32c and it also didn't want to go in. Again, any other 32c might have worked but the Marathon studded would not clear the bottom bracket. I imagine you could probably squeeze the 32c in if you deflated it before installing the wheel. But I think that's just asking for trouble down the road when you have to deal with flats/road side repairs. Also would likely not leave enough clearance for a bit of snow and ice build up.

So I ended up buying a 30c for the rear and a 32c for the front. In the Marathon studded tire, the 30c tire has a lot fewer studs. The 32c essentially adds another row of studs, so I figured it would be wise to have the wider tread and more studs on the front where washing out the front wheel on ice usually will have swifter and nastier consequences than a bit of skidding in the rear.

I have not mounted them on my bike yet, but I don't anticipate any issues getting the 32c to fit on the front even though we didn't specifically try it at the shop. On the front you don't have to worry about getting past the bottom bracket like you do on the rear so it should be an easy fit.

I ended up ordering some new wheel supplies. I went with Stans Grail 24h/28h, Sapim Race, and BHS hubs (Bitex). I'll be using a set of Schwalbe G-One Speed 700x30 tires set up tubeless. I'll hopefully have these built up and ready to ride in the next few weeks. Probably wait until I have a weekend of bad weather...it's just too nice in the western NC this time of year to mess around with building wheels!

Been loving riding my new Sirrus elite disc for the past 2 months and want to keep the party going during the cruddy winter months here in Seattle. Can anyone recommend fenders for the stock 700x30 setup?

Anyone try the specialized plug and play ones? They look sleek but pricey.

Looking for coverage but love the clean look of my bright red Sirrus elite so want to have as sleek looking fenders as possible.

I've got the plug and play fenders on my sirrus. They look and work great. They're matte black and blend right in with the tires. (My bike is matte black too). I think they were $50 and I had them installed when I bought the bike. Given what you already paid for the bike, I see no reason to buy anything else.

[/IMG]I considered the Specialized plug and plays, I think the install would likely be easier. They look great, but I was looking for more coverage and decided on the SKS Long Boards with mud flaps. I road a 52 mile day in the rain on the Katy Trail this fall and SKS really proved themselves.

Sirrus frame from 2007 / 8 era with a few changes....or a lot actually.

Not long to first ride now....just itching to go

andcb

Fairly certain it's the same frame as Mr Forresterace's bike with all the touring bags on it.
Very impressed with that build.

puma1552

anybody found 135mm wheel options?

I just built a set of 2016 Stans Grails with BHS hubs. Running them tubeless with Schwalbe One tires. Much nicer and lighter than stock.

Here is my Sport Disc.



I switched to 700 X 38 tires

I replaced a custom Look 695 top of the line road bike with a Sirrus X1 and couldn't be more happy. I made upgrades over the last year and literally changed every part except for the stem and the seat post. And it up investing over 6 K but the bikes exactly like I want it. I don't have any issues with back pain, I like the upright position and I get a ton of compliments on my bike. Pics to follow!

Similarity ?

Sirrus is a great bike for the Razorback Greenway. I started out with a Sirrus Sport and used it for my square to square rides. Alas I have parted with it now, but its with a friend still plying the Greenway. Now building a gravel bike that will also fill the role of the Sirrus. Here's the thing, I still want a Sirrus... hahaha

Great thread, thanks for the contributions from everyone. And whilst I've learnt a lot already I have a lot more to learn! I basically know nothing so hope to garner and gather as much as I can off you all over time.

I've recently spent 6 years riding around Amsterdam on a "city" bike that had 5 speeds, a steel frame, a bolt upright seating position and cost me EUR50. As they say in the Netherlands - your lock(s) should be worth more than your bike! I know nothing about modern bikes...

...so I went and got a 2016 Sirrus Expert Carbon because of course that makes sense!

But really it did make sense as it cost me ~US$890 which was only a little more than the alu disc alternatives that I was looking at. Came with a basic computer too. It is second hand but has spent most of its short life on a rack in a garage and still has the little warning stickers on the brake discs!

I don't even have a helmet (legal requirement here in New Zealand) or a lock, or fenders or anything for that matter so there's some more research to do before I pick it up.

Because apparently pics are mandatory here is one from the original owner... I reckon they look sexy as hell.

Great stuff, that is an awesome bike to begin your non-city bike, riding on.

djmcnz

Thanks Colonel!

More bike than I need but at least that means I can grow into it. Daily commute to work (~3kms) and lots of parks and "mountains" (not like Everest!) close to where I live. And I need to get fit. Perfect combo I reckon.

finch204

Beautiful bike!

It most certainly is...

Thoughts on the Specialized Sirrus Disc 2017? Reckon I could handle some off road trails?
