So I've set my Sirrus up in the basement with a mag trainer I bought about 10 years ago.

Early one morning this week I get on the bike for the first time and start pedaling - there's a lot of resistance. After a couple minutes, I smell burning rubber. I stop, look at the tire and see it's sorta warm. I just figure the back tire pressure needs topping up, maybe increasing the tension.

Next day I move the bike to pump up the tire, and realize I've burned a black strip into the carpet of the basement. Ugh. Clydesdale weight pushes the rear wheel down into the carpet.

So let my black stripe be a lesson to us all.

OMG that is funny, i'm sorry about your carpet but I could see myself doing something like that.

+1 Really sorry about the carpet...honest. Due to the snow and the fog my Trek is on its trainer, I think I better do a pre-ride inspection.

it helps to put the front tire on a block to bring the bike level. I found out the hard way last winter!

I use rollers and it is not a problem. But, I could see that happening to me anyway.

That stinks... no pun intended Sorry about your luck though.

LOL. put a couple of 2x4's under the trainer. Maybe that will lift it up enough.

Good food for thought. I just got a new Cycleops Jet Fluid Pro. I will have it downstairs with my hybrid attached to it. I will be putting down a mat so I am not too concerned about the carpet, but I will be watching to see if the rear tire touches the matt. At 249 who knows.

Doesn't make sense that this would help the vertical position of the rear tire. The trainer is attached at the rear skewer which is at the center of the rear wheel. The vertical position of the rear wheel will not change. When you pivot the front tire up it will change the weight split F/R and actually put more weight on the rear wheel (ever so slightly) and cause the tire to go farther into the carpet. I do recommend having the bike level for obvious reasons but I just wanted to clarify that it wasn't going to help his situation.

All that being said, put some boards or something under the trainer to get it off the carpet. You could probably just put it on a solid surface (3/4 inch plywood?) and it would probably not touch.

Time to get back to studying for Heat Transfer.

yeah, four 3/4" blocks was all it took.

and heat transfer was my best subject when I took mech eng. look at me now.

I'm glad you have solved your issue, lol. I would never have thought that would be a problem but then again I have never used a trainer.

I am just about to take my HT final tomorrow and I will be graduating in August from Auburn University. The next step is to find a job.

An inexpensive yoga mat or gym mat under the trainer does the trick (though I have put burns in the yoga mat) and also catches the sweat so it doesn't go into the carpet
