Great bike. (size 52) PROS: - Stiff yet comfortable, fast, responsive, all the things you'd expect from a specialized tarmac. - Ultegra Di2 works flawlessly. - Two piece headset is easy to work on. I've lowered the handlebar height as well as the stem length with no issues. Cons: - not home-mechanic friendly. Unless you have the tools and the know-how on how to remove a bottom bracket, route cables, bleed brakes, etc. it will be a challenge to work on. Meaning expensive trips to the mechanic if you want things changed. - 52 tooth big ring might be too hard for some people. - Roval cockpit is comfortable. I wish there was an option narrower than 38cm. - for Triathletes: finding some aerobars that work with the cockpit can be a pain. I've considered changing out the whole cockpit just to fit aero extensions on them. Overall, it's a good bike. If you're just using it to ride and you're not really a tinkerer it's solid.

Buscava uma bike mais confortável do que a bike 100% aero que eu tinha (BMC TimeMachine). A SL8 Pro é superior em tudo. Mais leve, mais confortável e tão rápida quanto. Não tenho adjetivos suficientes pra descrever a Tarmac SL8. Simplesmente perfeita.

My old bike was an SL6 which I had modified and was a pretty good bike and it went like stick BUT Comparatively the SL8 is a weapon! It took a little to get used too, my position was a little different but the first thing I really noticed was when I stood up in the pedals and put the power down and it wanted to whip whip left, whip right. Excellaration and power delivery is excellent, stability, smoothness and quietness sensational Love the Roval Rapide wheels matched currently with the S-Works Turbo tyres IT IS FAST! Reliably fast!

I love this bike I feel big differences compare with the toher bikes I have

Been racing 20+ years and have used many bikes, including a World Tour Bike from another American brand that's often compared to the Tarmac SL8. After 400+ miles in the saddle since purchasing, my mind is blown. The SL8 Pro is by far the best bike I've ever ridden and beats my previous ride in EVERY category. Somehow, the engineers created a bike that is stiff and snappy, while also extremely comfortable on less than perfect roads for 4+ hour rides. Descending is next level as the the SL8 tracks as if on rails. The CLII wheelset (swapped the 26mm stock tires for 30mm GP 5000S TR) winds up quickly and holds speed easily. I've been really impressed with how well the 51mm front wheel handles cross-winds vs Bontrager and ENVE sets that I've used in the past. I usually get blown around a bit ripping down the high speed windy canyons we have in SoCal but the SL8 has been rock solid and confidence inspiring. HIGHLY recommend this ride!

Amazing bike. Delivered as expected.

I’ve had lots of racing bikes & several Tarmacs. The SL8 is stiff, comfortable (with 30mm tires), & fast. If you have issues, it won’t be because of this bike!

I’ve been riding my new SL8 for about 3 weeks now. Absolutely love it! So fast and smooth handling. Upgraded from a 2015 Orbea Orca. This bike is from a different planet compared to the Orbea. Wow!

It feels like the Aethos and SL7 had a child - which is great.

I moved up from an SL6 and the changes with this bike are noticeable and make me faster. I love the bike and would highly recommend it.

Put a few hours on it, love this bike!
