I've been looking for some nice rim brake wheels locally for a fair while and the only options that regularly turn up are tubs, presumably the former race wheels for weekend warriors who now run disc group sets. So far some Dura Ace carbon options, and the inevitable Enve or Reynolds. I couldn't care less about aero and speed but they need to be reliable hubs and spin true.
Pretty hard to get Veloflex out here - Conti, Vittoria, Schwalbe and Challenge are the main options. Only hassle is I'll have to find a spare rim for stretching new tyres as well. Is that still a requirement!?
Tape, or glue?
afaik veloflex ceased production, i picked up a few nos on
ebay
i've tried vittoria and schwalbe (though actually they were rebranded veloflex carbons with schwalbe labelling) in the past, they were ok
not tried challenge, had some dugast silks but the tread came off in hot weather, never again
conti competition are pretty much a thinner version of the sprinters, a better ride but i found them far less durable due to cuts - btw whatever you do, don't touch conti gatorskin tubs with a bargepole, their lack of wet grip is appalling and they still cut/puncture easily, the sprinters are far better in both respects
glue for me, vittoria mastik'one, fortunately they still produce it
on some rides i carry a pre-glued tufo lightweight tub as a spare, folds up to about the size of an inner tube, the glue retains enough residual 'tack' under pressure even after years, just peel off the dead tyre and fit the tufo, with tape you can't really do that - one home, peel off, refold/wrap and it's ready for next time, reglue every few years
the only tubs i've tried that really needed stretching are the conti ones, the sprinters are a fight to get on a rim even after stretching, to get them on the stretching rim i use the old trick of first putting a foot in and pulling up with both hands, going right around the tyre until it's eased a bit (i wouldn't do that with a more delicate tub)
