Got some Bullet Ultra's (standard bearings) today for the Oltre and moved the shamals on the FG Lite Celeste.
Just did a ride with the Bullets and I have to say I am impressed. My regular training route has a bit of everything, smooth roads, crap roads, cobbles, paved etc.. It was a bit windy as well. They are definitely more comfortable than the shamals (both with the same veloflex and latex tubes - as a side note, the ride on these tires is so good that I'll be selling my tubulars). Power transfer is top notch. Even these are a couple 100g heavier than most tubular carbons, I did not feel it held me back much accelerating, only initially from standing still or going from very slow speed you notice it a bit (as compared to the zipps for example, these get a bit faster out of the blocks). At high speed they really shine, steady, and they wanna keep going, click a gear down and accelerate, cool
The weight is 900g for the rear and 750g for the front, so 1650g for the set. Not too bad and in range with the competition at this segment. It's kinda odd they get so little exposure on here, because its a really good wheelset I can't fault.
Sorry, pic quality is not very good, was getting dark and used the flash.
