Fast wheel on the flats and excellent climbing too. Smooth ceramic bearings. Has little flex left right for a 170 lbs. rider.
I have been riding these wheels for over a year. They perform well on ascents of the local canyons in Utah, the low weight and medium dish fly on the uphill. Making up time or drafting on the flats is where I really noticed the the 4.5's were a step above the wheels I was riding previously ( HED Jet 4). Although these wheels can slay it all, where they performed best was on the descents! Having stability you can trust while zooming down a canyon and knowing that when a turn comes you can trust the tracking of the wheels and really get into the turns. The 4.5's have just enough dish to feel the aero effects, but not enough that is catches cross winds. I would highly recommend these to anyone looking for a performance wheel set that can do it all.
