Newbie with some issues!

[JohnV]

I just took my road bike in the the shop last week because the last time I was on the trainer with it, a crunching sound was coming from the bottom bracket. I first thought that it was a roller bearing and since the BB is new, I took it back to be replaced. Got to the shop and there was no sound coming from the BB or anywhere else, for that matter. We took the bike an placed it on a trainer and set it up several different ways until we were able to reproduce the sound that I heard. It turned out to be that the rear wheel wasn't square on the roller and the bike was at a slight angle in the trainer. I have been using my trainer all winter and this is the first time that I heard this noise.

So my suggestion is to make sure the bike is square on the trainer and that you have the proper pressure against the rear wheel. I adjust mine by spinning the wheel and turning the roller adjuster until the wheel stops spinning. Then its an extra turn of the adjustment screw. Since I do a lot of riding on the trainer, I also rotate my tires every 500 miles so that both tires get worn evenly.
