Context: My "fast bike" is just a gravel bike with Conti Ultra Sport III (32mm wide) tires, and I do not train for speed, but endurance (total amateur, never been in a bike race, and don't plan to).
I put RideNow TPU tubes (36g version) in the tires a few days ago after hearing on and on about how good TPU tubes are.
I never had an issue with butyl tubes, and collectively, they've been trouble free on three bikes with a combined mileage of 15,000 km+ , so I've been pretty apprehensive about changing them.
The last three rides have been on TPU for about 150km. I've been riding in the same areas I usually do (strava says some segments have been ridden by me over 60 times).
My efforts have NOT been all out, and I'm not even trying to be fast (i.e. not getting aero as often as I could), so I come home quite fresh.
Over those 150km, I've recorded dozens of personal bests, including the first ride out with them, which had some nasty headwind.
I'm comparing my speeds with my previous bests, and they are something like 5km/h - 10km/h faster. This is with a ton of extra weight on my bike: metal bottles x 2 or 3, dashcam, headlight, bike computer, heavy-ass toolkit (butyl tube + hand pump + electric pump + multitool + extras...), frame bag, top tube bag, two "snack bags" hanging off the handlebars, and snacks.
Two days ago, I actually maxed out my gears at a cadence of 100 on the flats (over 50 km/h).
I'm speechless.
If this is the kind of difference that TPU tubes make, I honestly can't imagine what race tires would do. No wonder the pros are able to go so fast!
Is this the typical TPU experience?
My comment wasn't a personal attack on you, and I'm sorry if it came out that way.
It was more to the point that there are several options available for people with disabilities, and sometimes it does require either the cooperation of a doctor or a lawyer who specializes in this sort of thing.
Yes, you might lose a cut of what you're going to receive, but it's better than the frustration that you are going through.
Believe me, I've been through it. My wife's doctor was a complete ass, and it took years and years for them to finally be willing to sign the paperwork the disability tax credit.
And then when it came time to renew, this same doctor sat on their asses until it lapsed, and then she had to go through the entire process again!
It shouldn't have been like that. And if that's what you're going through, I can completely empathize with you.
I have another family member who had to get a lawyer in order to get ODSP, despite decades of suffering and being unable to work. It was only through the lawyer that they were able to get approved very quickly, whereas when they did it themselves, they were constantly being rejected.
Maybe there's a loophole that lawyers know about that we don't, but whatever it is, they do get the job done.
I do hope that things get easier for you and your family.
