    Gravel Flatbar & Carbon

    New offering from Specialized. Carbon, Flatbar, Future Shock, thru axles and 700 x 38 tires. Decent price.

    Thoughts?

    I think it hits a premium general rider that's not looking dropbars or a HT. Carbon flat bar city cruiser, commuter, and weekend bad-asser. For the carbon loving hipster. Got stay hip and on trend and steel is so 2015.

    Honestly a pretty cool bike for those looking for such.

    Not a new offering, I bought one over a year ago. I use it on an indoor trainer since all the exercise bikes don't quite fit the same as a real bike. I figured if I was looking at spending $2k on a Peloton or other trainer bike, why not just buy a bike that fits well and use a trainer. It is comfortable and I find I ride it 3 or 4 times longer than any exercise bike that I've ridden.

    I did ride it on the street once just to see what it felt like compared to my mountain bikes. I like my Stache and my Pine Mountain 2 well enough, the Sirrus can stay inside on the trainer full time.

    The frame looks premium but everything else... meh.

    NX stuff with a limiting 11-42 cassette, and I think the cheapest hydros that Shimano makes.

    lame video, it's just a new more expensive hybrid right? The kind of thing I'd keep at my 3rd house on the golf course to cruise gravel paths on the way to the club house...

    It's a newer model sirrus that fits wider tires, is set up as 1x only since there is no provision for a front derailleur and has the future shock like the Specialized Diverge.

    The Sirrus you bought over a year ago will not fit 38mm or wider tires, doesn't have the future shock and the geometry is different.

    ^^^ I agree. I don't think this new Sirrus model is "lame". Some people prefer flatbars. It's like the hardcore roadie/CX guy saying gravel bikes are lame because you don't need anything more than 35c. And the MTBer that says gravel bikes are lame, because dropbars are stupid and you're better off with a HT.

    Different strokes for different folks.

    That said, I do think this will do well with the hipster market, or at least hipsters with bad backs tired of riding their old school steel dropbar fixie.

    I compared the geometry of this new Sirrus with the Niner RLT which also comes with 700 x 38 tires...Pretty darn close...All the numbers were within a few mm ± of each. Not enough to make a difference and say that one is better than the other.

    Kinda looking at this for a gravel bike since I'm not a fan of drop bars.

    The tall stack sounds nice but that reach is pretty darn short for a flat bar bike.

    Nothing that you can't fix with the change of the stem.

    I guess, I just always thought flat bar bikes are supposed to be a bit longer. I'm confused.

    I hate being stretched out but essentially this geo with a flat bar would be like riding on the tops all the time on the RLT which doesn't sound ideal for long rides. Cool for zooming around the city tho.

    You don't think a 30mm longer wheelbase is significant?

    A difference of 1-3/16". I doubt you, I or anyone could notice that. Threw a couple other gravel bikes in for comparison. Wheelbase of the Tough Road is within 7mm (1/4") of the Sirrus X.

    If you think so... that's probably true for you. That's a normal size jump from xc-trail-enduro, where the wheelbases are longer and the change is less obvious.

    Cool looking bike. Lot's of good options in this space.

    I'm looking for a flat bar option to combine singletrack, fire roads, road and gravel. Just not comfortable with drops trying to shift and brake in the singletrack stuff.

    Looking to demo this bike and Niner RLT 9 one star, Giant SLR 2 and Salsa Journeyman come spring.

    These are the other 2 options I was looking at. But for the price and what you get I think the Specialized is the better deal.

    These bikes aren't carbon and are loose ball bearing hubs.

    I tried to upload a photo on the Giant advanced thread, but couldn't...
    I'm a bad old neck type guy so dropbars have me in a bit of pain.
    Switched in a set of flatbars on my Giant Adv 2. Absolutely love it and allows me to put in a lot more time on the bike.
    Has me feeling more like the bmx'er I was as a kid 

    I don't want to force drops on people but just because a bike has drop bars that doesn't mean you have to be in a stretched out aggressive road race position. I get neck pain very very easily and I love drops. On long rides they're much more comfortable compared to a straight bar for me. I can move around and the position just feels more natural.
    Gravel bikes usually put you in a more comfortable position compared to a road bike to begin with, you combine that with a few extra spacers and maybe just a bit shorter stem and you can end up with a super comfortable position.

    I think the problem is that drops come from the road world where you're considered a whimp if your stem is not slammed and your back is not parallel to the ground. So when you say drop bars people immediately think about discomfort.

    But of course run what works for you.

    I've tried putting straight bars on a road bike before but for me it didn't work out. Sure I got a much more upright position, which felt nice for a few miles, but on longer rides I just felt like my arms were locked out because of the super short reach.
    That's what I don't understand on this Specialized. If you check out the Salsa Journeyman for example the straight bar version is much longer than the drop bar version.

    Yes must say I can't argue with that. I did try out the drops that came with the bike and if I'd changed the head geometry around I reckon that could have worked. I do like the extra angles you can get your arms in with dropbars so it's probably the extra width up high with the flats that helps.

    I think it’s a nice bike. For longer rides I would prefer a drop bar bike (which I have), but I wouldn’t mind one of these for commuting, short fun rides or training purposes.
    If you prefer flat bars, go for it.

    Anyone know the max tire width on the Specialized?

    I know the Giant can run 29 x 2.1 ThurnderBurt's.

    Any idea if the Specialized Future Shock is compatible with any brand of bike?
    I was nearly sold on the Specialized because of this when I was shopping for my Giant.
    Would be a nice bit to add on.

    For gravel road riding a difference in 1-3/16" wheelbase means diddly squat.

    XC-Trail-Enduro wheelbase changes on MTBs happen because of the head tube angles. XC is around 70°, Trail is around 67-68° and Enduro would be around 65-66°

    Most gravel bikes and even this Sirrus the head tube angles are all close to one another. The difference in wheelbases would be a function of what the manufacturer specified for chainstay length and top tube length.
