My training wheels, Vision Team 30. And mighty fine they look on there, too. Not as many spokes as I'd like but it's what I've got (taking these to out to Paris Roubaix for the cobbles).
In the interest of being helpful, if anyone else is wondering how the hell to mount a pair of Challenge Paris-Roubaix 27mm then check out this video. Fitting the 2nd bead top to bottom whilst pressing down onto your feet like this creates just enough slack to get them over the rim. The hand gel seems to help also. Wouldn't have thought it possible until I tried it this way.
