Okay, I know I haven't seen it all, but I still am amazed by the things that can jump up and bite you in the @$$.

Short days and (much needed) rainy weather have kept me trainer bound for the last couple of weeks. Again, this morning, roads were wet, it was foggy and misty, and the report called for showers. So I drove, rather than rode (I know, I'm a wimp), to work. By 10:00, it had cleared off and the sun was peeping out at times. Sez me, 'Long lunch! @11:30, I'm goin' for a ride.'

But first some background. I'm new to the trainer thing, but had heard, and seen, that trainers do a number on your back tire. So I think, 'this is my chance to get some use out of some of these seedy old tires I've got laying around that are too bad to use, but I'm to cheap to toss.' So I had mounted an old $15.00 Conti SuperSonic that had been sitting around for, I dunno, 3 years? So far, so good. Worked great on the trainer.

Back to the present. Ride prep... pump up the tires. Ye olde Conti will be fine for a short lunch-time ride. Wrong! About 5 miles from home, the wheel starts "thump! thump! thump!" every revolution. 'Hmm', methinks, 'I must have put a big-@$$ patch on the tube at some point. Why didn't I notice it on the trainer.' A couple more miles, and POW!, thunk-thunk-thunk. The tire had separated from the wire bead, the tube had come out the side. The rubber sidewalls were hard and rotten (I knew that), but I didn't realize the rubber had come off the bead, leaving the threads exposed. And the threads were dry and rotten, too. So, the sidewall just pulled off the bead. The tube was hopeless (a good Michelin, no less), but I had a spare. Now, where's all the litter when I need a good boot? All I can say is a wet piece of cardboard does not make a good boot. I got maybe a mile on my minimally inflated tire 'til the second tube blew.

Long story short, it was only 4 miles home taking the shortcut, following the railroad tracks. The good thing about SPD-Rs is you can walk on the cleats. What the heck, I've been wanting to explore along the tracks for a long time. I'll make up the work time this week-end. :(

I feel your pain, when I took my current bike out for my first ride a couple of months ago, it too got a flat and had to trek back to my car for a total of about 4.5!!

Trainers can rip up tires, I used to swap out an old wheel when I would ride my road bike on my rollers. Then put the good wheel back to ride.

I haven't ridden on a trainer myself... why do they destroy tires?

bummer about the tire roadbuzz, better luck next time :(

The problem with trainers is that the resistance is always there wearing off the tread, i.e. no coasting, compounded by the fact that the tire always has the exact same angle of contact with the friction unit.

But in my case, the tire was just shot. The rubber on the sidewalls and around the bead was rotten, brittle, and flaking off.

So are trainers bad on wheels too, or just on tires? I am about to start using a trainer for the first time.

The only trainer that is particularly hard on rims is one that Minoura had out a few years ago that put the resistance directly on the rim. From my experience, the tire is the only thing that will wear down. I do the wheel swap, too, though, out of sheer convenience.

You can always find $10 road tires on clearance somewhere, too.
