I have to say. I put the Mirrycle mirror on my MTB. If it fits, Please get this. There is little to no vibration at all. I have a heafty fella with knobbies on my bike tires. Through Walking trails to the road the mirror image stays clears. VERY GOOD..>The Only downfall I had to build a stand so to speake to flip my bike over to lube the chain. No biggie though.
