Weeksy – A flow will work fine with a tube.
Original question – The Velocity blunts are good rims, stiffer than flows in my opinion but that may down to the build as the flows were hopehoops whilst the blunts were built by justridingalong. Had mine a while, they’ve taken a battering under my 99kg bulk and remain true, despite a couple of gravity endure races whilst fitted to my old yelli screamy. The paint doesn’t seem to be the greatest and has a tendency to flake but they may have changed this now as mine were from when they were branded a P35. However, as has been said above, if you’re going to run 2.4 tyres or bigger then duallys are worth a look. Noticeably stiffer again and really give a 2.4 ardent a huge profile.
