Using a set of 110s. Definitely worse in terms of grip, wear, and rebound, compared to Rollerblade Hydrogens, but they feel a bit better (i.e. at least grippier) than other cheap wheels like the Bont Elementals. A 4 for the price, a 3 overall I'd say.

My daughter used a set of 110mm for track in the recent Australian Nationals and loved them, more so than the Atom Boom!
