Hey, Hi Badger!!! I actually in Whiterock, just outside Vancouver. I LOVE Ontarion too, the countryside driving out to Niagra, beautiful, reminds me of my old country, England. You have a rural, gentle topography, we have the rugged stuff. The island is beautiful too, no doubt but the ferry really isolates it, swhich is god if you live there. Nice meeting you
I'm afraid that the south West Coast landscape, climate, and culture is just too ingrained in me; I miss it terribly, despite regular visits and stays. Any luck, be back for good within a few years. Would very much like to do out my time back home. Bonus: cycling on the Island is fantastic.

I'm sure I'd love matte green. This Cannondale Synapse tempted me a few years ago, and probably still would: https://bikepedia.com/QuickBike/Bike...x?item=1229990 (But, this is the hybrid forum...)

I have been on the hunt for a new flat bar bike and settled on the Sirrus X 4.0. Locating one has been a challenging task under the current circumstances. The good news is I have found one. It's a Large and 100 miles from my location. They are moving the bike from one of their other stores in that area to one closer to shorten my drive. The bike will be moved this Wednesday and I will travel this Friday to check fitting and testing and buying, if fitting works.
I have benefited from others on this forum about the Specialized Sirrus and choosing the best fit for them. My size at 67 years of age is 5'11" and inseam 30" (maybe 30.5"). So, I will only be able to try the Large. Wish I could compare it with a Medium. I have read that some found the Sirrus sizing to be somewhat on the larger size. I'm wondering about the Medium vs Large experience others have had with buying this bike?

Video?
I'm about ready to drop a video on the Sirrus' carbon downtube clanking issue. I've heard complaints about it as well as on LOTS of carbon framed bikes where hoses and cable housings rattle inside when they are not given specific routing locations. On my first ride, as soon as I hit a stretch of road I often refer to as "Streets of Roubaix" where the asphalt is cracking and lifting and makes for some harshly rough riding, my X 5.0 was making unbearable chattering sounds. Being carbon, sound reverberates everywhere and can be very tough to pinpoint but I heard about the issue and went right to the source the next day. Problem solved but it requires a little bit of effort.

I bought the Praxis crankset with a 40T rather then the 42T. You can run the OEM 42T on it since it's 3 bolt direct mount which is kinda-sorta a common standard. You just need to pay attention to offsets and chainline. The 40T works perfect for me in the hilly terrain single track riding and is perfectly ample for my road riding as well. It's sort of dependent on your terrain and topography. The more hills, the more useful that lower tooth count seems to be. So, to answer your question "Is it a great deal of difference?", I'd say no, not a great deal but a welcome change in ratio for the hilly terrain and seems to come with no noticeable top end penalty.

I've been absent and lagging on getting my video posted 'cuz I've been riding a lot and hammering on the core training trying to get back in the game. So, just for you, I uploaded the "Director's Cut" to get what I video'd out there. I didn't show the install of the mesh with the bottom bracket out as I originally installed but I think you can get it in there through the space in the access port as I show in the vid.

Regarding the BB, like Badger said, threaded GXP (assuming Rival runs that diameter) for 68mm BSA 1.37" BB shell.

Many thanks! I think i'm going for a 40t Praxis if i can find one.

Also, I went from a 40 tooth to a 38 on my Roll. Can't say I noticed any real difference. You'll pedal slightly faster in the same gears. So keep that in mind if you like how it feels now.

Hi I’m new.
So I originally ended up here because I was searching for an answer about 650b rims and tires. Saw the typical it’s somewhere in the thread responses to someone else asking. After 41 pages (it’s on page 41) I found it. (Yes I started from the beginning) Now my issue is that this site won’t let me quote the original post in a reply to it because I have to have 10 post before sharing pictures.
Anywho, I picked up a 2020? Sirius x 4.0, I’d share a picture but it’s at the LBS at the moment, about 4 months ago. It is the best/nicest bicycle I have ever owned and I love it.
edit: post about 650b set up was from 4/19/2020 ...... 19/04/2020 for you folks outside the US

I think I finally have my fitting dialed in on the Sirrus 3.0. It took some trial and error - seat forward, seat back, seat up, work on tilt, seat down, grips rotated a bit. The last couple of rides have been a pleasure. Now I have to figure out that faint but irritating intermittent squeak...

I added another farkle to mine. Being a pretty hard-core MTB'r...or Empty Beer as it may, I've been running dropper posts on my MTB bikes ever since they came out quite a few years back. Single-tracking the Sirrus X 5.0 down the chunky trails had me really missing that. Getting the seat out of the way for more aggressive and controlled down-hilling and tight maneuvering is made easy with one if these gadgets. Kind Shock Suspension happens to be my favorite version that I've run extensively and have the means to fully rebuild where others need to go back to the factory if not the trash bin when they start underperforming or break. Like any suspension-type component, they need service occasionally.
So, KS is the only simple lever actuated hydraulic 27.2 seatpost I could come up with currently. Since the Sirrus can't accommodate a third internal cable routing and I wasn't about to zip-tie a cable on my frame like I have seen some do nor did I want a remote lever on the handlebar that's necessary for the cable actuated models, I bought the uber-simple lever option with 100mm of drop which is more than enough for this bike.
Here's a couple pics to show fully extended and fully compressed and it has unlimited adjustment in between. Weight isn't too bad since it's an uncomplicated lever activation. I just left my factory seat mounted to my S-Works CG-R carbon post and put another Specialized Body Geometry Power Arc saddle on the dropper. This way, to switch between, I just pull the post and insert the new one to a pre-marked position on the stem and torque it to 55N-m.

Steering Stem Question
Sirrus Elite Carbon arrived today. this bike is so beautiful my girlfriend is going to be jelous. I can see the metallic flakes in the teal blue paint. I am coming from the hardtail mountain bike scene so I am seeing alot of neat features for the first time. I am stoked to say the least.

Hi Mike. The stem cap screws into the future shock, but the stem itself is a standard stem. If you saw my posts, I have replaced the stem with one that is shorter and with a bit more rise. You just have to use the original cap to screw back into the shock.

Well holy crap....my apologies. I didn’t realize the regular Sirrus that year didn’t have the future shock. Not sure what the heck that stem is...Specialized and their stupid parts.
Let me ask this, what would happen if you took the stem and the spacers off? Could you use round spacers on the steerer tube and a regular stem? Is the steerer tube still round and 1 1/8? Install a star nut (if needed) and you’re good?

It looks like the cap is simply integral to the stem itself. So you'd pop the stem on top of the steer tube with the appropriate number of spacers to keep it off the top of the steer tube, then you'd run the center bolt down enough to preload the bearings, then you'd tighten the side bolts.
The only real benefit to the standard "through hole" design of most stems is you can lower them on the steer tube and stack spacers above them. You can't do that with Specialized's stem, but it looks like there's also no reason you couldn't replace the stock stem with any other stem of your choosing (including a "through hole" stem that uses a separate cap). Most stems do not come with a top cap, so you'd need to buy that separately.
