I really enjoy taking Spin.  All of the instructors are great, and the workout has really improved my cardio fitness.

But.....

There are a few things that have bothered me in my recent classes.

One of the pedals on my bike has been broken in each of my last three classes.  I used three different bikes and each time had the same problem.  The pedals are worn out.  The bearings between the pedal and stem are gone.  This allows the pedal to move up and down.  The up and down motion makes a clunk or pop occasionally and allows my knees to move in a way I don't like.  Bike numbers were 10, 13, and ?.  Now I know to carefully check the pedals on any bike before setting up and starting class, but others may not be so lucky.  Will you please do some bike maintenance?  Maybe have a list at the front of class for a couple of weeks to note problems.  I know that the guys fixing the bikes don't have time to ride each one for 30 minutes and diagnose any problems.  Let us members help you out.  This will make spin better for everyone.

Hot spots.  There are a few spots in the studio that are really hot.  I have noticed that the AC vents at the front of the studio are arranged in no particular order.  Would it be possible to adjust the vents so that they evenly cool the entire studio?

Thanks for reading.  See you in Spin.
