Tubs

I've heard this all before... I don't buy it.
It's possible to justify any cycling purchase if you spend enough time convincing yourself of the relative benefits.

Sure like 10 and 11 speed clusters. Carbon wheels etc....

I could submit my own batch of anecdotal evidence that tubs are no more reliable than clinchers and that pitstop doesn't always work, here

Sealant is NOT the solution. Tubulars should not mean sealant. One can repair them with needle and thread. Sealant is really for tyres such as the Tufos and for "emergencies".

(I started writing it and everything.. ) - but the bottom line is is; your ability to repair/boot a clincher and it's tube by separating the tyre into component parts makes them so much more useful for day-to-day training.>

One can repair and boot a tubular too. For the weight, however, a tubular tyre will generally be robuster.

Day to day training? Unless you are riding in preperation for a race you are not training. A lot of training is not even on the bike. Nearly all of us here are riding for fun. We don't train, we ride. Our gear is not about trying to get a competitive advantage but about enjoyment, even luxury or status... Nice tubular tyres provide, I think, a nicer ride.
