It sounds like this isn't the forum for you, no need to get mad about people discussing upgrades. Enjoy your 1981 bike.froze wrote: ↑Tue Aug 06, 2019 5:35 pmTubolitos are freaking expensive, I don't get flats now so what advantage are those tubes? I haven't had a flat in 6 to 7 months with butyl tubes. I'm not going to pay more than three times as much for a tube unless they can prove they'll last through 12 sets of tires or longer! As the new thing to do is to brag about it requiring less watts to run...like a 1/2 to maybe 1 watt...news flash, you can't even detect that! In addition to that expense of the tube you have to buy their patches at $15 for the kit.
All of this snake oil marketing about aero this lightweight that is pure NONSENSE! Did you know that since 1981 the average speed of the TDF has only gone up 1 1/2 to 2 Km (which is about 1.2 mph faster) per hour to 2019? And that's with far better aeroness, lighter bikes and wheels, stiffer bikes and wheels for more power, better training, better diet, and better doping! http://bikeraceinfo.com/tdf/tdfstats.html (for fun look at the average speed for 1971 and the early 60's) So now someone is going to tell me about the huge gain I'm going to get from using expensive tubes? LOL!!! People will buy into anything. If I bought all the stuff that claims they save 2 to 8 watts on various parts I would be saving roughly 150 watts on my bike...ok, next please.
If anything tubolitos are one of the most value for money weight upgrades that are discussed here. Approx £30 extra for around 200g saving over normal butyl tubes.
