Brake lever plus shifter lever

Perfect! Thanks very much for clarifying :thumb:

Thank you for the explanation! Just learnt a new word...

I read that with Sean Connery's voice....................:lol::lol::lol:

So I want to ride this bike more in the gravel now.... But I want different tires for the gravel (38s). That said, ideally I want a different type of wheel so its a quick swap if the ride that day is gravel versus road.

Any recommendation on an affordable wheel set and tire combination for more gravel riding? Thanks!

It can only take up to 32mm tires.

You need to buy a Diverge now.

The EW-WU111 is compatible with Ultegra Di2 6800 (I have this) and the new R8000 along with the Dura Ace versions that also utilize the CANBUS system. See Shimano compatibility charts at e-tubeproject.shimano.com/pdf/en/HM-CC.3.3.2-00-EN.pdf. The biggest issue that will catch the largest number of people is battery compatibility.

Yep, you need the newer battery. It has more memory that is needed for the Bluetooth.

Hi Everyone,

I´m new here and I´m looking for some advices for the Roubaix. I have a 2016 Diverge (Comp DSW) and will replace for a carbon endurance bike. I also have a good pair of wheels and hydraulic lever and brakes to put in the new bike.

The 2018 Roubaix Sport was the perfect choice for till I notice the carbon frame grade is the lowest onde (Fact 9r).
The price difference between the Sport and Elite (Fact 10r) is huge where I live. What I know is the 10r is a little lighter and stiffer then the 9r.

Does the extra money worth for the better frame since I want a good upgrade from my top end alloy frame?

Thanks!

The "lower grade" usually means that is has more resin in it. That also usually makes the frame a touch more compliant and a touch less brittle. It does not mean lower quality. In fact, it could be more durable. When they squeeze out more of the resin, the weight is reduced and the frame becomes slightly lighter and stiffer. I am not sure you will even be able to tell the difference if a frame is 100-200 grams lighter, if it is the same model.

Are you swapping all your parts from the COMP DSW onto your new frame when you get it? How much does a LBS charge for labor to do that usually?

Sorry for the misunderstanding. I have these parts besides my Diverge. I'm going to buy a whole bike and ask to only change the wheels, levers and calipers.

Thanks for the input!

If you're early enough, you might be able to get Fact10r Roubaix Sport as I noticed on my local dealer bikes.

I have just received my Specialized Roubaix Expert Ultegra Di2 2018 in Carbon/Red which is a really nice colour however the cassette fitted to the rear wheel is a 11-34 & should be a 11-28 according to the manufacturers spec. Normally i would not think about complaining but where i live it is mainly flat so the 34 cog & the subsequently 30 cog would not get used at all. This basically means i have 2 gears less to use where i would be using these instead in the mid block of the 11-28 cassette. What are your views on this?. I have not spoken to the supplier yet.

Odd that it's not to spec. LBS should be willing to swap it out to your liking at no additional charge as long as there are no miles it. Else you can sell it or keep it tucked away for any hilly granfondos in your future.

Yes very strange indeed unfortunately i have used the Roubaix over the bank holiday weekend here in the United Kingdom. Its like anything you get a new product & all you want to do is use it (not wait for the online supplier to advise on what action would need to be taken). This alone would take substantial riding time away from myself due to no fault of my own. I also found when connecting then re- programming the di2 through the e-tube project that the original settings were for a 50/34 along with a 11-28 cassette. I then changed these settings to the 11-34 cassette more so so that Sychro Shifting can then be applied correctly. I also found that when the bike is in the small ring it will not go into the last 2 small cogs i.e the 11 & 13. I know you should not do this anyway as it is cross chaining which puts the chain under extreme stress but surely you should have control over this & not have the software applied to stop you from doing this. I presume this is why i cannot do it but maybe other forum members can have their input on this matter.

Not exactly...lol. Ratio of resin to fiber elements doesn't change much. Fiber filaments have to be encased in resign for stability of the matrix. What changes is the modulus of elasticity...the flexure modulus of the carbon fiber filaments. Resin doesn't change much. Because higher modulus fiber elements are used aka stronger, less are needed which reduces weight for same level of stiffness. A lower modulus carbon fiber bike maybe less or more stiff than a higher modulus bike. Generally there isn't a lot of difference, but rather weight is reduced by using stronger carbon fiber therefore less is required. The resin substrate is secondary to type of carbon fiber aka modulus used.

Wow a 34/34 low gear. I had a bike with a 42/34 and could spin up hills. But you're hardly moving. 34/34 has got to be strange. Wall climber gear...hopefully you dont tip over.

I could not agree more. It is pointless having such a huge cog if you are not going to use it. Still cannot understand why the bike had this cassette fitted instead of the advertised one. I will need to contact the supplier to find the answer to this and hopefully we can come to some arrangement so i can either swap it over or they the supplier send the correct one out. I have previously rode up some of the steepest climbs in Britain including the famous Hardknott Pass & only once have i needed a bigger cog than a 28 to get up it & that was after 95 miles of hilly sportive climbing. Obviously everyone's fitness is different so maybe for some cyclists this might be ideal but for myself it would be wasteful.

Not being able to engage 34x13 or 34x11 is a "feature" built into the Di2. It prevents extreme chain angle on bikes with short chain stays. (Not that the Roubaix is very short in that area). Shifting into 34x11 may cause the chain to come into contact with the big chainring...not a good thing. Changing the cassette to an 11-28 is not a big deal and just takes a couple of minutes but you also probably have a medium cage derailier to accommodate the larger cassette. Swapping the derailler is a slightly bigger deal. Not an absolute must to swap to a short cage derailler and shorten the chain but that is the right way to do it. The fine print on most bike spec sheets usually says something like "subject to change without notice".

Agree that your situation is better served by 11-28. Hopefully your supplier will accommodate your needs.

Thank You for explaining the reason why you cannot engage the smallest 2 cogs when in the small chain ring. It makes complete sense. I have just had a phone call from my supplier regarding the cassette & great news is he has agreed to send out the original cassette that should have been fitted to the bike in the first place (there was no mention of any subject to change without notice in there terms on the web site) unlike most. He also never mentioned about returning the original cassette so i presume from this i can just keep it. I am a bit concerned now with the medium rear derailleur fitted as he never mentioned changing this to a short one & i myself never thought of asking. How critical is it to swap these over. What i am basically asking is would the medium derailleur still function exactly the same with the 11/28 cassette once it arrives.

For those who'd had either a Roubaix or Diverge for some time now, how is the FutureShock holding up? Just curious.

While I am at it... There is something bothering me about the design, and it's the fork clamp which attach the fork to the FS. The fact that the steerer is essentially held in place by a single bolt seems somewhat risky - you get a single point of failure at the most critical part of the bike.

Couple thousand miles on mine. No issues.
