It's NOT pointless or a bunch of extra effort. I'm not keen on losing training time fixing flats on the side of the road. As I read recently, if tubes were cutting edge they'd be used in cars and on motorcycles...your mileage may vary but it's hard to argue with 6 versus 0 (and this seems to be pretty consistent from what I've seen from fellow riders and read on-line).
So feel free to continue to use tubes, I'm happy to loan you my spare tube as I haven't yet had a necessity to need it. Heck I'll even help you replace your blown tube if you ask nicely. Oh yeah, and the GCN guys haven't mentioned that it's actually safer if you have a front tire failure as Tubeless tires are MUCH less likely to blow off your rim due to the tighter fit in the rim.
Throw in a wider rim on many of the newer (HED C2+ for example) tubeless ready wheels and you have lower rolling resistance = faster at the lower pressures. There are a lot of benefits, too many really, to simply dismiss as 'too much effort'.
My goal is to take 21 minutes off this time to finish at 2:40 this time. Let's see if I can do it...
now let's see if I can manage a 21 minute 5k this week at States, which would be an incredible win for me.
So for all of you neigh sayers who insist that this is useless new tech - I certainly hope it's not you who loses your front tire on a downhill. I don't get all this tubeless hatred. Are road riders really that out of it? MTB riders are effectively all tubeless these days, I believe, and they put a lot more stress on their rims...and run lower pressures (bigger volumes).
read through the comments, there are many folks who've gone from multiple punctures per season to zero. So unless you are getting paid to ride your bike, this is probably something that would make your life just a little better. So have a think when/if you buy your new set of wheels...
A final thought - Simon, man you can't compare tubeless to tubed at the same pressure. AND I'd add it would be wonderful if you got your hands on a pair of HEDs new 25mm C2+ rim based wheels. Pair those with a wide enough wheel, let out the pressure and then tell me what you think. Maybe a little bit 'soft' for you liking? How about the cornering? Like riding on rails mate. In this case it's all about having enough space to take the tech to make the spec...where's the mystery? I'm not sure I get it?
Crits are a special animal, for sure. But for competitive time trialists and triathletes getting there is very important too. And a single puncture can ruin your entire race (in this case potentially unnecessarily)
finally on the blowout item - we agree here. Not common, extremely unlikely. But given the chance to completely avoid it, I'm willing to pay 10% more and invest the extra effort and time. However unlikely, it might just be my own life I'm saving. (I have read about improperly installed tubeless going flat on the front and still staying on the bead...but I've never heard of them coming off the rim as you said.)
previous best was IM 70.3 Maryland at 5:29:10.
Big improvements from more structured and consistent training. Still not the percent decrease that saw. Thanks for your support
Sadly, you're right. The only rides out to Coco Luxe for me are going to be in my mind for a while. Maybe they'll let me get on the trainer in a while. I dunno. The Coco Luxe run would be awesome. I bet many folks in the club might want that but won't it be one HUGE video file? It would be fun to see you do the Mapso hill workout with that thing, especially with the sound turned up to catch all the swearing and crying , I mean commentary.
