The new Tarmac replaces the curvy SL5 with a much more angular design, with slimmer tube profiles and dropped seatstays. The new frame has lost some serious weight too, with the S-Works version now 733g, over 200g lighter than the SL5 S-Works. Our test model is the next rung on the ladder down from the S-Works FACT 10r carbon frame, weighing a still-light 950g.
A new, super-light (sub-300g) fork is designed to be size specific, so the steerer tube profile changes across the range to ensure consistent handling whether you’re 5ft 6in or 6ft 5in. Specialized has done a similar job with the Tarmac frame, if you look at the down-tube dimensions between smallest and largest sizes you’ll see a significant difference.
The frame comes with a Shimano Ultegra groupset running a 52/36 and 11-28 combination, which is a great gear choice for what is aiming to be a racing all-rounder.
Specialized provides the finishing kit, starting with the new SLX24 rim brake rims, which, like their disc cousins found on the Roubaix, have a new, wider profile, adding extra girth to the classy S-Works Turbo Gripton tyres in an already generous 26mm.

The rims are mounted onto DT Swiss 350 hubs using DT spokes for a taught, responsive and light (1460g) wheelset.
The Tarmac features a semi-aero D-shape carbon seatpost, topped with own-brand Body Geometry Toupé Expert saddle. The slender SL stem holds a very well-shaped shallow drop bar wrapped in thick, comfortable tape. Specialized has got the contact points right, which add to the luxury feel of the Expert.
The previous generation’s SL5 was one of the best-handling race bikes around, and this one feels every bit the same. That’s not really a surprise given that the geometry between the two hasn’t changed, aside from the addition of 3mm to the bottom bracket drop to counter the trend towards bigger tyres.
The numbers suggest an aggressive riding position, which is true, but the new frameset is one of the most comfortable race bikes we’ve tested. The rear end is a revelation with the D-shaped seatpost offering plenty of flex and the new fork reducing vibrations.
The relatively low overall weight and low weight in the wheels make the Tarmac a joyful companion on climbs. Once you start to head back down again, the new direct-mount Ultegra brakes offer a solid, vibration-free feel wrapped in levels of control that are the best you’ll get from traditional rim brakes.
We are massively impressed with the new Tarmac. The sharp responses are glorious, and the smoothness of the ride is exceptional, but the price of entry is high.
