If you plan on racing a Grand Tour this summer, sure, go rock that S-Works. But if you're on the hunt for a glorious ride that can smash both a local crit and your friends on the weekends, you'll feel right at home on the Tarmac Disc Expert.

In order cut some grams from the Tarmac, but to also ensure that it's stiff and compliant in exactly the right places, we took major steps to improving our Rider-First Engineered™ technology. From different layup schedules and materials, to visibly different forks, we scrutinized every single aspect of the Tarmac to ensure you're getting the perfect ride. With this revamp, we also updated the geometry, basing it on countless Retül data points and professional rider input. This enabled us to develop a Performance Road Geometry that perfects the combination of a responsive front-end and short wheelbase, which delivers instantaneous response and optimal power transfer.

And while stiffness aids in the aforementioned, compliance must also be utilized for an optimal ride quality. That's why we designed a seatpost that builds compliance into the upper 120mm where clamping doesn't happen, dropped the seatstays, and altered the seat tube shape. We also added tire clearance up to 30mm, which translates to a 28mm Turbo Cotton on a Roval C 38 Disc wheel. This allows lower pressures for decreased rolling resistance, increased traction, and more comfort. Altogether, these additions still have the Tarmac riding like a true race-machine, but it also takes a bit of the sting out of road imperfections. You'll thank us on your next long ride.

But why disc brakes? The real question is why not? They offer superior braking power and modulation, work exceptionally well in wet weather, and offer a very, very minor weight addition. All this means that you have more control and can go faster with more confidence.

We also know, however, that aerodynamic improvements are the most important thing we can do to make you faster. Our Bora-Hansgrohe and Quick-Step Floors Pro Tour riders, after all, are demanding aero improvements on every bike. With this, the aero goal was to discover where we could essentially add aero for free, by not taking anything away from the hallmarks of the Tarmac design. During the six-month iterative process, three areas were discovered where we could do this—a new fork shape, dropped seatstays with aero tubes, and a D-shaped seatpost and seat tube. The result? A bike that's approximately 45 seconds faster over 40km compared to other lightweight bikes in the same category.

The build spec on this Tarmac Disc is value-packed, featuring Shimano Ultegra mechanical shifting, Shimano hydraulic disc brakes, a Roval C 38 Disc carbon fiber wheelset.

無論您是與朋友周末比賽,為了奪下新的KOM還是超越PR,在當地的公路比賽中一枝獨秀,Tarmac Disc Expert都是專門為實現這一目標而設計的。透過騎士優先科技車架確保不同車架在不同的材質、製成下,都能提供一致的完美騎乘品質,增加了一些空力優勢,讓它在40公里的賽道中可以比其他自行車快上45秒,而且輕量20%。沒有什麼比它更輕、更快、操控更靈敏。

這款 Tarmac Disc Expert採用Shimano的 Ultegra 機械變速套件,強大的碟煞制動、Roval C38碟煞碳纖維輪組。

在Tarmac Disc Exert的結構上,我們利用先進的航太複合材料優化軟體,徹底革新FACT 10r碳纖維的製程。此為我們目前所開發最先進的材料,能夠使車架減少接近200克的重量。沒錯,車架重量減少了20%。

空氣動力學優化是我們讓你更快速的關鍵要素,但在Tarmac Disc Expert上,我們在不增加重量的前提下提升了空氣力學優勢。通過研究,我們發現有三個區域是我們可以精進空氣力學優勢的一個新的前叉形狀、帶空力優勢的後上叉、以及D形座管以及立管。最終結果?在40公里的賽道上能快上45秒的Tarmac。

升級後的幾何形狀是從無數的 Retül 資料庫和專業騎士的回饋而來。這使我們能夠開發出高性能的幾何,完美地將靈活操控和短軸距優勢結合起來,提供即時地操控回饋和最佳的功率傳導。

為了增加順應性,座管在上方 120mm 部位加入了彈性。我們還將後上叉往下修正,改變了立管形狀,並將最大支援輪胎寬放大為30mm。

我們使用了500個碳纖維布料創造出7種車架大小,但都以「騎士優先科技」確保Tarmac在正確的地方保有剛性及吸震性能,我們重新檢查每個車架大小的每塊碳纖維布,只為了達到最好的性能。為了讓您有完美的騎乘體驗,不同的車架大小採用不同的碳纖維布堆疊方式、不同數量的碳纖維布。有時候甚至使用不同厚度以及不同種類的碳纖維布料。
