A little light fettling, as the summer season approaches. It's now *even* lighter! The crankset has changed from R8000 to Dura-Ace 9100. It's a compact, with 170mm cranks. took a while to find one at a decent price - everything is 172.5. Brakes - again, upgraded to Dura-Ace 9100. Shifters - yet another upgrade. They're now Dura-Ace 9050 Di2. A wireless unit has been added, so I can connect to my head unit. Wheels are back to the Mavic R-Sys, already super light at 1295g, but they're shod in Pirelli P-Zero Race tyres - nice and light, and fast. Inner tubes are Pirelli TPU, so they're light too. Overall, I reckon it's lost about 350g, maybe a little more. Final weight for now - about 6.3kg.
