I just yesterday put on 2 new training tubies tufo s22 260 grams per tire . I had s33 tufo and they lasted one season. My new tires have more tread nice and round for the price of less then $25 a tire. I havn’t had a flat problem where I live in the country. I don’t think the tubies are much more then a nice clincher price wise and I like all the crap that goes with the tubies. The glue smell and fussing with them . I don’t have over $600. in my bike so I don’t mind spending a little more money on tires. I think the most imporant parts for good road feel are tires and wheels. Reflex rims 32 spoke durace hubs make a nice light strong wheel. I don’t know what they weighbut I don’t think new lighter wheels would make me any faster. I bought my first tubie bike in 1970 a PX10E. I guess I am just stuck in a tubular rut. Life is good.
Depends on the course. The rough chipseal of Ironman New Zealand I went with with a more supple, larger cross section tire like a VeloFlex Criterium, 22mm. On the now smooth Kona coast, VeloFlex Record, 19mm. Ironman Canada has that crappy section of pavement on the out and back and over Yellow Lake so I choose the Conti GP, same for Wildflower and Vineman. I haven’t ridden the high end Tufo road tubies, but their cyclocross tires are second only to Dugast, and those are $100 a piece. Super supple.
I’m a big fan of the Tufo s3 Lite. I haven’t tried the new Tufo Elite Jets (<160g) but I bet they’re pretty damn good also. I will say the new Zipp tubulars suck. They’re heavy, slow, and they don’t wear very well.
