If Tarmacs are rolling off the line within 100 grams of a Venge, it’s almost not worth it to get a tarmac unless you want rim brakes or that 100 grams
Yes.. thinking the same. Actually starting to wonder what the point of the Tarmac is unless you want rim brakes. Is the ride quality a lot different. Feels better climbing, cornering is sharper?
From what I’ve heard the lay up is different meaning the stiffness varies so you get a different ride quality. Both have the same geo so I don’t know how much that layup difference varies the ride quality.

I'm looking at a set of direct mount EE Cycleworks brakes for my SL6, size 54.

I see that there is a SL6 specific rear brake for the G4, along with a front/rear brake, and a chain stay brake.

What I am wondering is if anyone is running G3 on this frame? The G3 only seems to come in a front specific and a rear specific configuration.

It's quite a long thread, but hopefully someone had tthis problem before.

I'm looking into buying a new wheelset for my S-Works SL6 rim brake. Question is how wide of a rim can it accommodate and how much will a 25/28mm tubeless tire balloon on a rim?

I'm running Dura-Ace BR-9110RS which came standard with the bike. At this point I'm considering two options of 36mm profile rims (training wheelset).

Which one would work best for the SL6 frame?

1. 25mm outer / 18mm inner width

Image

2. 28mm outer / 21mm inner width (hooked profile)

Image

Unfortunately, I could not find the dimensions of Roval CLX 32 rims that came standard on ultralight frames. Currently, Roval website lists them as:

Rim Width: 20.7mm internal, 28.1mm external

But I'm afraid it could be a newer model than came with original SL6. Will it have enough clearance on brakes and chainstays?

Thanks in advance!

Is this the cleanest way to route the wiring for the cockpit?

Just curious if someones found a way to clean it more despite the external wiring for the front brakes.

I also own the S-Works SL6 Tarmac rim bike and run the awesome Roval CLX32 wheels. As you state, the current spec on the Specialized web site says that the CLX32 inner width is 20.7", or close to your 21" inner width option. I bought my CLX32s for a previous bike, before I purchased the Tarmac. To my recollection (this was late 2016), the inner width was the same then as it says on the web site now. I recall this because when I was shopping for the wheels in 2016, I was looking for a wider inner rim and was focused on this very metric.

A point to alert you to is that there is not a lot of vertical clearance from the top of the tire to the front fork and rear seat stays, again on the rim brake model, for the nominal size 28mm tires I have used most of the time (Pirelli P-Zero Velo) on the CLX32s. [I have not had problem with horizontal clearance to the brakes.] I am running the wheel with tubes, not tubeless. Every once and a while -- probably 3 times a year -- very small, thin, dry leafs have been caught on the part of the fork that is close to the top of the wheel, or on the top section of the seatstays near where they meet the seat tube. It's the darndest thing -- I can hear the leaf rub and scratch against the tires, which is annoying; the leaf does not fall out on its own when I ride, it stays stuck; and to remove the leaf, I have to take off the wheels because the leaf is so small and wedged in such a tight space that I can't pry it out otherwise. I thought it was a fluke when it happened the first time, but it's occurred since then. Not a major problem at all but strange.

Per Rolling Resistance Review, the P-Zero Velo at the size 25 has a measured height of 25 mm, and a measured width of 27 mm. I don't know how this translates to the size 28mm I run. Anyway, what I'm saying is that I'd watch out for vertical clearance, tire height, if you want to run larger tires.

Thank you very much for extensive reply! At this width no brake rub when working out of saddle? I was considering 25-28mm tires for 21mm ID. In case with 25c tires, I'm concerned with inflating to the point when you'll be cornering on sidewalls (e.g. tire too small for the width of the rim)

Correct, I have not had brake rub issues, even when the wheels are not absolutely perfectly true.
