I ordered a Conti training tire. So I pulled off an old wire bead 23C Old school Gran Prix to pop it on... Apparently not a day too soon either. ;)

That is the third tire I have had bubble, delam, or blow out. ;)

But that trainer tire is quiet, like really quiet!

Your bike is not square in the trainer. It is getting overheated.

I just run on a treadmill at the Y.

12/17/14 7:03 AM

Either it's not square to the roller or the roller pressure is too high or low. I have had an old, already used Vittoria Rubino Pro on my Performance house-brand fluid trainer with a couple of thousand "miles" and it's still in good shape.

I ordered a training tire for the same reason. Had a Michelin delam earlier, lots of slippage before it was obvious. I think the loads generated by the CT cause this. The trainer tire is quiet, doesn't slip at all for me at much lower clamp forces, and will likely last forever. I don't think its a "square to the trainer" issue.

12/17/14 7:44 AM

Ha ha, I do it every time but mostly because I find it a good warmup. Plus the software whines at me if I don't. The software is rather officious, particularly Smelly's...:)

FWIW, I use a conti trainer tie which works fine, but not a lot of use yet.

12/17/14 8:02 AM

The real reason...Sparky is just putting out too many damn watts. I'm surprised to see that the tire did not melt.

12/17/14 12:03 PM

I calibrate after a warm up. Be doing CT since the 90s. I used to install and maintain 6 in NJ, whihc was mostly PC work I admit.

I do not see how it is possible to not be square with the CT stand. Fell free to elaborate on how that might be the case. I don't think so simply put.

I think it is watts. I take full advantage of the fact I don't have to worry about riding home bonked and do mostly high watt intervals.

I suspect the load/restriction the generator affords and me popping 500 watts typically seated really pulls on the rubber. The idea being to sustain longer and longer. And I typically use older road tires. It seems when the rubber gets thin enough to start flatting on the road, the used tires slip less.

I never bought a trainer tire, as I always have used tires about, and tires I won't use on the road that come on a lot of these bike I grab and flip.

This 23C was mint, I would rather have sent it up to my kid that toss it. ;) I have only lost one 'good' tire early on before appreciating what the load gen does heat and friction wise.

Actually built up a dedicated trainer bike for the new trainer tire also. Old Spesh Allez I wound up with in a trade. It fits most importantly and I will just leave it on the CT. Same Geom as the Roubaix mostly. That old brooks is super comfy, will see how that pans out on the trainer.

32/44 and 12-27 9 speed, parts is parts. ;) Wonder how long it will take for me to bother cutting that steerer. Little chance hitting it on a spill on the CT. ;)

Trainer bikes are the schizzle. I gave mine away and still regret it.

12/17/14 1:29 PM

I took it on a few test spins up the hill in the sub-division here. A testament to how stiff carbon bikes have evolved. My latest road rides are the Roubiax, discs/fenders/wet, et al. Thus my current baseline of road feel.

This old AL Allez with 23C tires at 85/90 lb air on the hill was not as stiff one, and on the broken pavement in one section rode as well as the Roubaix with 27mm Paves. And with a $200.00 seatpost that cost more than 1/2 what this Allez is probably worth. ;)

And the Allez is still under 20lb with a 2.5 lb saddle and the goofy bulky orig pedals that came on the Roubaix. Of course it has clipless for the CT use.

I use my Ottrott. Hey, I don't use it for anything else, it fits great and the carbon and ti won't rust...

12/17/14 2:13 PM

We have a post stroke rider on our team who has difficulty changing tires and even pumping them up. We fitted his bike with Tannus tires (The harder 700x23 model) They are airless (actually have a decent ride) and also calibrate well on the CT.

Try it. Worth the 45.00

12/17/14 2:36 PM

Been on the CT 10+ years have a dedicated trainer bike on it a Bianchi Premio w/ DT shifters used to use old tires but got sick of finding them either flat or delammed right before I wanted to hop on the trainer so got the Conti trainer tire and have never looked back since....

12/17/14 2:39 PM

"Tannus tires (The harder 700x23 model) They are airless (actually have a decent ride) and also calibrate well on the CT. "


So takes a step out of the air up and calibrate process. hmm...

How many Pins/holes per tire? Are you using a 23 on the CT? They make a 28 too, assume you are talking Musai ?


"actually have a decent ride"

Define/elaborate if you will, As in as compared to what?


EDIT: Hmm, the Thoroki for adventure/gravel perhaps?

12/18/14 7:25 AM

So you don't really need the brakes?

12/18/14 10:35 AM

No, don't need brakes, bit they where on there so I cabled them up anyway... I could pluck it off for road duty if I wanted...

My trainer bike used to be my Ti Blade up until I moved the trainers out to the fixed up section front portion of the shop and move the CTs out there so I could get the Del Sol in the garage. ;)

But I wanted the drop bar on the CT. Although for plain CT watts workouts [aka TTs] the Blade on there worked pretty well and the sweat does not bother the Ti. I suspect even though I am not a Dr. or Lawyer [nor have I played either on TV], the OLD Ti bike fits into the category of not being worth selling. So the CT is a good place for it really. Considering I do not use it for the intended purpose. ;O

Started out with my TCX on the CT in the new area, but twice I wanted to take it out. And too much of a hassle to pull them on and off the CT IMO.

12/18/14 3:12 PM

Well that Brooks saddle on the trainer bike after two CT sessions made me realize something. My low low lower back [tail bone] has been bothering me of late. Been riding the Roubaix with a saddle the jury is still out on. I think it may have just come in...

That saddle, a Selle SLC, is really good for the center relief. But after my Brooks sessions, I think I need to take that Selle off. I thought I was getting some compression issues in my lower back, and now need to rule out that seat. I think too narrow a saddle pushing outwards on my pubic arch / synthesis could be causing this. I have had this before on narrow saddles, usually faster than the few hundred miles I have logged on the Roubaix with this seat. Argh...

12/18/14 3:23 PM

Yes I guess it could be seen as a bit over the top, but hey, I rode the Ottrott as my primary road bike for 9 years, it still looks new and I'd still ride it happily had not the RS shown up. Plus the fit is very close so I can spend a lot of time on the trainer and transition easily to the RS. I even thought for a moment of taking the Ottrott to Mallorca so as not to expose the RS to travel, but naaah, the RS is the bike I want to ride.

12/18/14 5:03 PM

Even the Conti trainer tires wear out on me roughly every 2 to 3 years...kinda pisses me off.

I've got a Litespeed as a dedicated trainer bike, the second one on there since I managed to break (wear out) the first one. I've always run DT shifters on the CT bike, seemed a waste to use sti and a violation of the kiss principle.

Hey Dan, I can hardly wait to tell Smelly his software is officious...he thinks there's something wrong with me because I STILL use the Nintendo system. If you look up the word luddite in the dictionary you'll find my picture next to it.

12/18/14 5:10 PM

"seemed a waste to use sti and a violation of the kiss principle"

Agree mainly. I used the Sora STIs that I pulled of the Roubiax. Seemed like a good place for them, well the STIs, DRs, Chain. etc etc.

12/18/14 7:05 PM

I don't have brakes on my trainer bike so it is lighter. :) I also have downtube shifters.

12/18/14 7:09 PM

Lyskey must be proud of all of the Litespeeds seeing ct duty.

Tell Smelly his new web design rocks.

12/19/14 9:15 AM

Yeah, Sally's CT bike is also a Litespeed :-)

I'll pass that message on to Smelly, but what's a web???

Did you know he was a big UFC fan? I don't know why I find that ironic...but one day he came over to watch a PPV fight night and mentioned that he didn't quite understand how an arm bar 'worked'. Sally offered to show him, he said okay, so about 3 seconds latter he was spread across our living room floor tapping very adamantly :-0

Now I ain't got no PhD, but I can tell you there's no way I would ever ask a question like that to Sally!
