2017 S-Works Tarmac Quickstep upgrade in progress...

[Racingevo]

Hello,

I built the bike up from a framset and cobbled everything together from some of my old bike parts, some new, and some I knew would be temporary. I have a Supersix Evo 54cm and decided to size down to a 52cm Tarmac that I got for a decent price. It's heavy but it rides beautifully.

I'm currently upgraded from 6870 to 9150 as the mechs become available. I thought I would document the weight differences between 6870 and 9150 as I upgrade.

9150 RD mounted for now while I wait for a new chain

Right side 9150 shifter: 113.4g
Right side 6870 shifter: 152.8g
Interestingly, I notice that on the Dura Ace shifters, the band clamp(?) is made out of titanium and weighs about 5g less than the Ultegra steel clamp. Left side shifters are within .1 grams of the right side so I didn't bother posting those pictures.

Shifters mounted quickly for now. I'm debating getting some 40cm handlebars....

There is a definite improvement in tactile feedback from the buttons but still nowhere near Sram e-tap feedback. I'm a little underwhelmed. Also, the buttons have a nice thin rubber anti-slip coating for extra grip.
