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?
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
