Can anyone confirm if the Specialized Roubaix family have a BB30?

Thanks

What year? Seriously, they had some bikes with BB30,they call it OSBB, but they have since switched to PF30...and still call it OSBB. Now both of those options take the same cranks but a different BB.

Currently the SL3 Pro SRAM, SL3 Pro, SL3 Pro Di2 and S-Works models have the OSBB...and the S-Works frame set (but not the SL3 Pro frame set). Campag4Life posted a pdf from Specialized in another thread that listed which frames have exactly which BB standard in them.

For 2010-2012.
Thanks for the tip, I'll see if I can find that post.

Again it doesn't really matter if it is BB30 or PF30. BB30 uses an aluminum sleeve in the BB that is machined to tight tolerances and the bearings are pressfit into it. PF30 is the same width and uses the same 30mm spindle cranks but the aluminum sleeve in the BB is omitted the the BB assembly has a delrin cup set that is pressed into the frame. They went this way because the frame tolerances don't need to be nearly as tight and the delrin cups should help reduce the creaking issues many people have had with BB30 and other pressfit standards.

Here is that chart. 46mm Carbon BB is PF30, 42mm Aluminum BB is BB30.

Thanks for the info GC.
I think i'm BB30 brain-washed.
Need to change that.

I think I am too...but I just ordered a BB86 frame (Giant Defy Advanced). I did just find out though that I can get an adapter BB and run a Rotor 3D+ crankset which is BB30ish. https://www.velotechservices.co.uk/sh...cat=7410001832 Now if I can just find a 3D+ crankset for less than $700 with rings.

I'm using a KCNC adapter on my BB30 frame and it works very well with my Ultegra 6750 crankset.

X...because of the confusion of what BB a Roubaix can have relative to model and year, best to post with what bike you are interested in and ask. Its not really straightforward. Will give you an example and G-chopper touched on this. Take the Roubaix Pro that I just built. The 'frameset' ordered from Specialized is threaded...one of the reasons I went with it. The complete Pro bike however is what they call OSBB which is BB30. This is because Specialized crankset that comes on the Roubaix Pro complete bike...the Spesh crank only uses BB30 or PF-30. FWIW all Specialized S-works bikes are PF-30. Given a choice, I prefer threaded first...because I don't put out the watts to need the 1% stiffer BB30 ...and prefer PF-30 second. PF-30 is a bit more resilient to making noise for an integrated BB.
Hope that helps.

What Campag said... the answer is you will find both types of bottom bracket in 2010-2012. If the spec sheet for the model you are looking at on specialized.com says the bottom bracket is "Threaded", it's not BB30. If it says "OSBB", it is BB30.

My SL2 (2012) has a normal 68mm bottom bracket from what I can tell.

I have a 2010 Roubaix SL Pro that has OSBB

Ok, thanks guys, again.

i was about to start a thread obout this...

currently i ride a 2011 sl3 roubaix and will upgrade to a 2011 sworks sl3 roubaix (HTC). i read somewhere the htc version is bb30, but that doesn't sound right...

i wonder what are my options now..will i need to buy an adapter? new cranks? its a bit confusing....

@Grassshoper - im also lusting over some rotor cranks! they look so sweet!

I just got a Tarmac Pro SL4 and it has the alloy BB30 style.

It came with cups to use a shimano crank and I ordered some for SRAM GXP. Very easy to install and no problems/noise yet (but only ~500 miles or so). I do have my concerns with the design since it all just slips together with tight tolerances, but time will tell. To me, the threaded BB's seem like there is less opportunity for issues.

This year's S-Works will have PF30 unless you are getting an HTC team frame and they got something special...as a team bike I would think there is a chance that the chart I posted earlier could be ignored...I don't know their arrangement. My guess would be that it is PF30 which uses BB30 compatible cranks but a different BB. As an example this: https://fairwheelbikes.com/hsc-pf30-c...it-p-4122.html Rather than this: https://fairwheelbikes.com/hsc-bb30-c...it-p-3689.html The cranks used will be the same...any BB30 compatible crank (which the 3D+ are).

Yup....all Tarmacs are BB30...except the Tarmac S-works which is PF30 like the Roubaix Sworks. I will go out on a limb and say the threaded BB is becoming endangered as much as I like it...and if Specialized releases the SL4 Roubaix next year as proposed by some, then it will likely be BB30 as well.
How do you like your new SL4? Reports are it is a whale of a great bike...bit softer in vertical flex compared to the SL3 Tarmac but mega stiff when standing on the pedals.
Cheers.

If you ride the 2011 Roubaix SL3...it is likely BB30. That means if you go to the S-works SL3 Roubaix for 2012...and me personally if you, I would wait another year because there isn't much of anything between the two bikes...then the new frame will be PF-30. What that means for you if moving your cranks over to the new bike is...they will be plug and play...no adapters needed...or...if they are external threaded bearing cranks on your '11 bike with adapters...just bring all hardware over to your new SL3. The reason for this is...BB-30 and PF-30 is interchangable for cranksets...cranks can't tell the difference between the two...same spacing and same bearing ID.

I really like the frame. It is super-stiff compared to the 09 Tarmac Comp it replaced, particularly in the front end. I can't compare to the SL3 since I've never done any significant miles on one. The real test will be in the spring when the local crit series starts back up. I'm itching to see how it handles at speed.

Thing I admire about Specialized is how they continue to improve the breed. They don't let much grass grow. I finally joined the club. Have been looking at Roubaixs for a couple of years now and with all the improvements to the SL3, had to jump on. I do a lot of long rides and appreciate the comfort and more relaxed riding position. and yet the bike is stiff enough to keep up when hammering. I thought long and hard about the new SL4 Tarmac...great racing bike. May have to pick one up as a stable mate to the Roubaix...or maybe a Venge.

my current roubaix is 2011 sl3, and its being replaced by specialized (warranty) for 2011 sl3 s-works (htc team edition). Told the LBS about waiting for 2012 models, but this isn't an option. Who's gonna say no to an swork upgrade! NOT ME

Guys - I'm starting to get it, but in case I mess up, can someone tell me if this is the right bb that I need for a 2011 Spec Roubaix Pro?
If not, which one would it be?
Thanks

EDIT: I did do my homework; the Roubaix Pro is OSBB, therefore it's BB30 compatible. Gosh I hope I have that right.

This is painful. I'm about to ask someone to take me out back and shoot me. Just not in the face, please; what if you miss?

This is a close up of the Roubaix Pro osbb area. I don't see an "indent" where the bearings will stay put for the Shimano 105 crankset, so I'm thinking I need
- to install a Shimano press fit
- then install the bearings
- then install the Wheels Mft. bb30 adapter kit.

Am I close?

Actually I don't think...sorry.

The frame pictured is 68mm English threaded. Currently if you buy a Roubaix SL3 Pro frameset you will get a threaded BB...if you buy the S-Works frameset you will get OSBB. The SRAM RED Pro and DA Pro SL3 non S-Works models for 2012 DO have OSBB...but the Ultegra model is threaded.

Personally if I had a OSBB frame I would run a BB30 crankset and not try to adapt it back to threaded for Shimano or Campy cranks with 24mm spindles.

IF I was going to run a Shimano crankset I would go with an adapter more like this one (shown above by M_Wales): https://fairwheelbikes.com/parlee-bb3...et-p-4500.html or this one: https://fairwheelbikes.com/kcnc-bb30-...et-p-2926.html

I don't like the WheelsMfg concept of an adapter in the BB30 bearings. This style presses in and then houses the bearings (sort of like what PF30 is).

OP, as others have said, it really is a frame-by-frame issue, unless you are talking S-Works.

Last year, when I purchased my wife a Tarmac SL3 Pro frameset, I was asked whether I wanted the standard BB or the OSBB, as Spec. offered both options for that frame in the color she wanted.

You're both absolutely right. I've gotten down to the bottom of things and the frame is confirmed to have an OSBB.

So now my options are a bb30 crank or adapters.

I'm slowly getting it now. Thanks
