The Tarmac SL6 was our 2017 Bike of the Year:

It's a bike that can truly do it all - light, stiff, aero, rides well and handles like a dream... it's universally regarded that Specialized have absolutely knocked it out of the park with this bike.

As soon as I tested it (and started devising ways to delay its return) it was clear that this was the most impressive bike I had ridden in 2017.

Now Specialized have brought out the eagerly awaited Disc version, and it retains all the virtues of the rim-brake model whilst adding the performance (and reassurance) of disc brakes.

Bespoke Boss Barry wanted to really put the SL6 Disc through its paces. Where better than the French Pyrenees? Fast, twisty descents, mixed weather conditions, this is a real test for any bike.

Read how he got on on the Bespoke blog.

It rides just like the rim-brake version, which is undoubtedly a good thing. There's maybe a touch less reaction when climbing out of saddle but I could be imagining it.

But the other benefits are so obvious... and it has a Powermeter built in! I know £9250 sounds like a lot; but there is nothing you need to change on this bike.
