Totally agree with you! You've hit on something that totally baffles me...why some folks think putting an 8 inch block under the front tire somehow equates with hill climbing! A block does not equal overcoming gravity

GLC - Never seen the type of trainer you mention, but in general I want resistance (aka wear) on the tires not the rims....they after far cheaper after all!
