Sirrus X Comp vs Expert/Pro

I am looking at one of these bikes and would appreciate any opinions on them or experiences you have had with them.


The main differences with the X Comp appears to be the 1X system with a top gear ratio of 3.82 and the Expert/Comp's 2X system with a top gear ratio of 4.36 and the X Comp's 8mm wider tires.


I like the simplicity of the 1X system and the Comp's lower price point but don't really need the 38mm tires as most of my riding will be on paved roads. I also wonder if I will miss the higher top end speed of the expert/pro or if the difference won't be that noticeable for my purposes. The bike will be used for fitness, short to medium trips, and possibly urban commuting.

Have you looked at the new Canyon RoadLite 7.0. quite a bike for the $1499. I just purchased two of the RoadLite 9.0 LTD and love them. The build was very easy. I put a thread on here about them if interested. The 7.0 uses the same frame but with a 2 x 11 105 system while the 9.0 LTD uses the 1 x 11 Force 1. I didn't know if I would like the 1 x 11 system but it works great. Good luck on your hunt... the the best part as once you have spent your hard earned $$$$ well you know. But do yourself a favor and at least look at what Canyon offers. The value for what you get is better than any other name brand IMHO.

Duplicate threads; ask the mods. to delete one.

To the questions: no experience, but I've ordered the Sirrus X -- to replace my 2010 Sirrus Comp as main bike.

I wanted the "Future Shock", but went with the new Sirrus X rather than Expert for a couple of reasons (cost wasn't an issue). First, I wanted a 1x bike -- like you, in part for simplicity. The Expert/Pro could easily be converted, but I like the fact that the 'X' has a dedicated 1x frame. There's no provision (cable or derailleur mount point) for a front der.

Second, that frame may also have slightly greater tire clearance than the Expert/Pro, which were said to be good with up to 35mm tires. It may be though that Specialized just squeezed 38s in there. I don't know, and don't really care -- the frameset clearly has clearance for 38s. I plan to switch tires to Roubaix Pro 32s (what I use now) or the new Conti GP5000 32s in any event, but do want the wider tires for riding light off-road, which I do on occasion.

Back to 1x and gearing -- kind of like saddles, that's a personal decision only you can make! I think in terms of gear inches, and for me the stock 1x gives a range of 103 to 27 gear inches. That is perfect for me; I will never, ever use that top 103 on the flat, or anywhere except maybe a very long road descent -- doubtful, even then. At the other end, that 27 is plenty low enough for me given my riding conditions. I like climbing, and around 30 is my usual 'bail out' gear on a long difficult climb. If I modified the gearing at all, though, it would be to a smaller chainring to gain some extra bail out if I were tackling really mountainous terrain.

But that's me; I'm older (67) and tend to spin lighter gears at a high cadence, and am not particularly concerned with 'speed'. The other thing with 1x that bothers some people is the gaps between gears. Again, not an issue for me; I do all my riding solo, so I'm not concerned with 'matching', and the gaps don't physically bother me. I'm used to them from mtb anyway.

So I'm happy with the dedicated 1x set-up I've ordered. I suppose the other thing is that if you were unsure, you could always get the Expert/Pro and convert to 1x if you wanted to try it. You could at least 'go back' -- no can do with the X version.

DowneaseTTer, I will look at Canyon, thanks for the suggestion.

badger1, thanks for the comments. I haven't ridden a 1X yet and will be trying the Sirrus X this weekend. I have heard about the wider gear gaps and will be looking to see if that bothers me.

I am considering a Sirrus X Comp also and hope to try one out this weekend. I am not sure about the 1x11. I live in Florida, so I am not really concerned about my normal riding. I will not push the upper end of the gearing, but my concern is how I would do climbing hills. About the worst "hills" that I ever face are highway overpasses. My other concern is that I am pushing the weight limit, although I have not had any problems with spokes or wheels on previous bikes.

Supercharged and Badger1: Please keep us informed about your experiences with the X Comp.

I live in Florida and ride a 1x8, have zero issues and my "hills" are pretty tall bridges....you should be fine on a 1x11

Will do.

FWIW, I can't see even the stock gearing causing any problems at all in Fla. I don't live there, of course, but I've spent lots of time in (and riding in) the SW (Naples area). If your riding conditions are more or less like that area, then gearing is a total non-issue.

Wheels? Understood, but ... here's a trick: if you do get the bike -- or any 'stock' bike from one of the major mfgs -- just have the shop re-tension and re-true the stock wheels as part of the purchase. The Sirrus X has cartridge-bearing hubs, so no worries there, but machine-made wheels are often slightly askew (tension and/or true). That simple step can often mean that the wheels will be good to go for miles/miles.
