Is everyone aware that Michelin are going back into the tub market later this year?
Is this really due to buying customers demand, or to increase Michelin's profile in the pro sphere. I like their tyres and have used them continuously for over 30 years. I still have some sprint wheels but would never go back to tubs. The hours spent unstitching repairing and sewing them then sticking them on the rim only to puncture on the next ride. Fine for pros with a team car and mechanics. Tubeless with sealant is the future, same ride quality as a good tub and real puncture resistance.
I don't use my tubs at the moment, because I don't race (probably won't ever, but the dream still glows somewhere).
If I did race again, it would still be on tubs, and good ones at that - every little bit of help would be needed!
For most racing that I would do I'd get a free lap out, or there might be service, so a puncture isn't a problem. In a time trial, if you puncture your chances of a place or time have gone anyway. I never raced on repaired tubs, and it's generally frowned on for road races or the track because of the risk to others.
