The weight of my old wheels was higher than these…I do not recall exactly, but I want to say about 100g for the set, so not a lot really. I doubt if that is all that I am feeling here. I have found that over the years my first impressions of a product are often the keenest as I am comparing it directly to what came before. After a while, a slight or even moderate change feels ‘normal’ when you are on the bike, but it took quite a few rides before I took the quick response of the Rolf Prima Hyalites for granted.
I have not had them for as long as would be required to test durability in all conditions, but after many hours of riding, the Hyalites are still very true even after some decent impacts that took the tire to the rim with a bit of a ‘twaaa-PING’. At 1550g or so rolling down the road, they hit a nice weight for aluminum and certainly seem stiff enough for my 190lbs. However, when faced with a significant enough impact, aluminum dents, and it will, if taken beyond it’s limit, twist-up and want to stay that way. Carbon does not act like that. It might crack and fail, but it won’t bend and stay bent. It has a ‘digital’ failure mode….it is pretty much all zeros until the clock strikes One, and a cracked carbon rim is headed to the bin. But you can ride a dented, aluminum disc brake rim for a long time and unless it prevents the tire from seating/sealing correctly, you likely will hardly hardly notice it. And there is always the hammer, drift, and block of wood treatment to ‘help’ the rim bead back into shape.
