  • SAM BENEDICT: Welcome to SBCU.

  • We're going to talk about the all-around performance road

  • bike, the Tarmac.

  • This bike does it all, and does it all fast.

  • We're going to talk about how this bike climbs, how well it

  • handles, and how it just gets up and goes in the flat out

  • fastest sprint you could possibly want.

  • So let's talk about the climbing

  • ability of the Tarmac.

  • Now, this bike is insanely light.

  • This is a sub-900 gram frame in the S-Works, and we were

  • able to take the stiffness to weight ratio up 19% over the

  • previous generation, the SL3.

  • But to pull that off, it's not easy to do, and the engineers

  • spent an incredible amount of time looking at every fiber,

  • every bit, every way to construct the frame.

  • And what we have here is a new way to

  • build the FACT IS frame.

  • So the frame is actually constructed in

  • four separate pieces.

  • You have your top-tube, head-tube, and most of your

  • down-tube are really unique.

  • One piece BB chain-stay, your c-tube, and then your seat

  • stays in the back.

  • And when you can build these pieces individually, you can

  • build them for the weight, the stiffness, exactly what you

  • need to do, and come out with the best product that's going

  • to fly up the hills, but also be nice and stiff, exactly

  • where you need it.

  • So this is the SL4 frame, super light and stiff.

  • So the handling on the Tarmac is part of what makes this

  • bike so much fun to ride, very responsive, very snappy, comes

  • to life right underneath you, and we're going to get that

  • from three parts of the bike.

  • First part is in the front end.

  • The head-tube angle, this is a pretty traditional style

  • head-tube angle, steep, agile.

  • It's going to respond to your inputs.

  • But if you look closely, you'll notice it's a tapered

  • head-tube, 1 1/8 to 1 3/8, leading into this big old

  • beefy fork here.

  • And that's going to give us a lot of stiffness, a lot of

  • confidence when you're laying into those corners.

  • Moving down towards the bottom of the bike, the bottom

  • bracket is low.

  • You're going to feel planted in those corners, but it's not

  • so low that you're going to scrape your petals when you're

  • peddling through the corners, so a lot of speed, a lot of

  • confidence.

  • And then when we move into the chain-stays, short

  • chain-stays, going to be responsive, make the bike easy

  • to accelerate and get up to speed, very good flickable

  • turning, as well.

  • So at the end of the ride, it's all about the sprint.

  • You've got to put this away, put a bow on it, come across

  • the line in first place.

  • And the Tarmac is constructed to do that, and there's a few

  • places that we want to talk about, how we get that done.

  • The head-tube here, this is a hyperbolic head-tube.

  • So it's got this interesting shape to it, where there's no

  • flat edges, and what we're trying to do there is make it

  • light on the top, but don't allow the carbon fibers to

  • breathe and flex at all, just make it super stiff and

  • responsive.

  • So when you pulling on the handlebars and really just

  • trying to get every ounce of power out of the bike, it's

  • not going to move underneath you.

  • Going down to this big old beefy down-tube, it's going to

  • be super stiff, and then into a really unique constructed

  • one piece bottom bracket chain-stay.

  • This is where the power transfer is all about.

  • You want those two pieces together, no interruptions,

  • big, stiff, light.

  • Put the power down, Tarmac's going to take

  • you across the line.

  • So three things I want to talk about on this Tarmac here that

  • are super cool.

  • One is the Roval Repede CLX40 wheels.

  • Just like the bike, these things are all about being

  • lightweight, and stiff, and getting up to speed and going.

  • So, these are 40 millimeter clincher carbon wheels with

  • sealed ceramic bearings, super nice.

  • The crankset here, this is our S-Works FACT crankset, very,

  • very light and stiff, crazy light and stiff, also really

  • cool that it comes with standard gearing.

  • That's 53/39, but if that's not your style of gearing, you

  • want to change it out, great, no problem.

  • It has a removal spider.

  • You can put whatever gearing on there's

  • going to make you happiest.

  • And the last piece-- the one that's going to take us home--

  • is the Body Geometry saddle.

  • Doesn't matter how fast or slow you're going, you got to

  • stay comfortable on the bike, you got to keep blood flowing

  • where it needs to be flowing.

  • That Body Geometry saddle is going to do exactly that.

  • So that's the Tarmac, the all-around performance race

  • bike, one of my favorite bikes to ride the whole wide world.
