I got a couple of GrandStands (http://www.thegstand.com) to help organize the very tight space where we store our bikes. I've noticed that some bike shops use them to display bikes on the floor so I figured they must be OK for the bike. I put my rear wheel in the stand and I just don't like the way the spokes lean into the sides of the stand. No matter how narrow or wide I set the stand, the plastic visibly presses into the spokes. Am I going to damage my spokes by using this thing long-term?
