Ti axles now available (not for me though). Also much lighter rear brake hanger
Perhaps they've been available for a while, but this is the first I've seen Ti spindles for the 12
I'm passing them up though, or at least the front axle... my front only weighs 14 ounces, and so Ti, at 60% the density, could only be saving 5.6 ounces, or a touch over 1/3 lb. That is not much savings for 195 British Pounds, or about $340. (Would work out to over $1000 per lb saved which is a way higher rate than I'm willing to pay even for unsprung though nonrotating weight.
The rear would be a little better deal since, as a guess, the stock rear axle might weigh half again as much, in which case the cost per lb saved might be more like $700. Still too much for me.
But, for some serious race bikes, those could be both be things to jump right on.
Probably for most an item of greater interest, and certainly better cost efficiency, would be the rear brake hanger for 145 Pounds:
They say it saves over a kilo, which means over 2.2 lb. Not bad for 145 Pounds. Plus, the stock rear caliper is a pound heavier than for example the Discaciatti rear caliper, so changing out calipers too could save a total of 3.3 lb there. That's pretty cost-efficient for unsprung weight.
