It’s a 54cm 'Supernova' colourway, it’s certainly lighter than I was expecting!

Chopped some 60mm off the seatpost, and changed out the bolts to Black TI
A 14.6g saving!

Anyone know of a source for a carbon cradle that fits (the current one is 17.1g and the ones I have are about 12g, but too shallow to fit)

You can save more grams by swapping the barrel nut too but it requires some Dremel work because the readily available titanium barrel nut is 1mm too wide.ImageImageImage

Thanks Aryeh, when you say readily available barrel nut, where did you buy it?

Also, cut down the fork (as will only need a 10mm spacer)
344.6g > 333g - a 11.6g saving

Incidentally, the frame and fork combo comes in at 1015.5g, pretty light!

Image

And had to cut down the Spec expander (the fork was finished quite badly inside, which stopped the plug going in all the way at full length)

A 9.3g saving (Still toying with getting the Aethos or Carbon-Ti Expander to save another 20g's)

First Ride was yesterday on a Sportive, the bike felt amazing, so responsive accelerating up climbs, corners like on rails, would go as far to say it's the best bike I have ridden...

It's supposed to be like that. There's a ridge and reinforcement down in the fork steerer.

I get the need for the ridge and the reinforcement around the hose exit hole, but this was a mess inside. I ended up using a Carbon-Ti X Bung thing anyway..
