Query: Doesn't fit my bike seat

I would've guessed that in buying a Bell product they would have made it universally fit bikes - it doesn't. If the pole holding up your seat isn't the right circumference, this thing won't work. Lousy. It may work for your bike, but it's probably not worth the risk in buying it to find out. Find another product.
