Nice bike, it looks like you've still got the older, feather light Ultra along with the CT-X fork :thumbup:

My 2017 Ultra (size L, though), was nearly 100g heavier, and fork (CT instead of CT-X) gave you another 40g handicap.

About 1km into my first descent on my brand new bike the front tyre blew off and I stacked it at about 50kph. Ended up costing me quite a bit in damages and French medical costs, and the upshot was I lost all confidence in the heat dissipation of the wheels. That's what led me to the Lightweights and the conti race lights as they are just that little bit thicker and hopefully safer.
:shock: good that you're still here to tell us about this, scary!

Go for tubs & sub 5kg, tubs still rule climbing and descending.

Correct me if I'm wrong, but I don't think the veloplugs are relevant as with the construction of the Lightweight wheels, no rim tape is needed.
Were there any damages to the front AX Ultra 28 clincher rim? You mentioned the front tire blew off due to poor heat dissipation, were there any obvious hot spots on the brake track / delamination afterwards? Were there lots of switchbacks on the decent, where you had to be aggressive on the brakes? Just trying to understand the whole situation, as I have the same wheelset and don't want to be in the same situation. I'm running Turbo Cotton tires with Vittoria latex tubes on my Ultra 28 wheelset. Originally, I had Vittoria Corsa G+ tires on there, but replaced them when my brake pads were slightly rubbing on the sidewalls after being transported in my car (I guess the brakes must have been bumped during transport somehow)

The braking performance on my Ultra 28C has been nothing short of superb. Nice stopping power with a very linear feel, much better than my Lightweight wheelset, but not as good as the new Enve textured brake track wheels.

Cheers.

hi,

just wondering when you take off the chain off the crankset, does the crankset spin freely or does it only do 1/2 or 1 revolution?

You might save some weight from using thinner/less bar tape, bottle cages (carbonworks?) and cables (powercordz) without sacrificing durability etc.

It's great as it is though, and I'm mighty jealous of that frame weight! That's weight that I can never save; great platform for your lightweight build.
