My latest project: Specialized S-Works Tarmac SL4 (6.6 kg)

Here is my latest bike build project. This time, it’s a rebuild of an older model. I got hold of a frame from a Specialized S-WORKS Tarmac SL4 from around 2012. In my opinion, it’s one of the coolest S-WORKS bikes ever made. The bike has won everything from the Tour de France to various classics. Alberto Contador, Peter Sagan, Tom Boonen, among others, have won on this model. The bike is assembled with new and used parts I had lying around, and they’re standard components—not any exotic ultra-lightweight parts—so it’s impressive that it only weighs 6.6 kg, including pedals and tires with tubes.
