I've got the the velo solo one on my cutter atm, and it's fine. It's only been on for a few months, but so far it's been great. Downside, i would say it's very heavy, and like others have said, not particulaly nice looking, but if you don't mind about a bit of extra weight and looks then they are great. Also velo solo do a 15t cog so it's a bit better for trick set up's with the smaller chain rings.
