S-Works Tarmac SL8 Red Sky – Custom Build

With a sprinkle of Gold

It’s all about the details with a custom build with Certini and this one looks incredible in the flesh. With this build we had to be clever as the budget did have a limit and they were keen to get their best bang-for-buck. Despite Ultegra Di2 not being the lightest of Shimano’s groupsets ( Why would Dura Ace exist otherwise? ) we managed to get a total build weight of 7kg ( Including pedals) with aero wheels. The rider was keen to retain comfort, so even managed to squeeze in 3D printed S-Works Power Saddle and 35c tyres for that weight.

The keener eyed amongst you will notice the gold titanium bolts. These even replace caliper bolts, seatpost, shifter clamps and many more, with a total weight saving of 68 grams, it’s actually a worthwhile upgrade as well as being pretty.

One trick to keeping weight down, is to use a Dura Ace cassette and KMC DLC Chain. Just these 2 items save 115 grams over the Ultegra.

One area that no short-cuts are made are wheels, using Enve SES 3.4s with custom decals, we have the perfect combo of lightweight and aero, suitable for the endurance bike the rider requested.

This colour really has to be seen in the flesh to be appreciated. The glossy, candy-apple like red with the contrast gold finishing touches make this an absolute dream build.
