## Description

desertcart.com : Park Tool Tool BBT-27.3 16-Notch 49mm : Sports & Outdoors

Review: So important to have the right tools for the job - I have a bottom bracket where the ONLY way to tighten and untighten due to the width of the external BB being less than a millimeter is using two of these tools. One on each side and a friend to help turn while I hold the two tools on with a fair amount of pressure. The good news is that I don't have to take my bike to the shop for BB adjustments anymore. The bad news is that I had to purchase two of these tools. I had previously tried (unsuccessfully) to use this tool along with the flat handled counterpart tools. My bottom bracket is Wheels Manufacturing PF30-THD. These tools when paired up like I described above do a surprisingly good job given the extremely thin BB material to work with.
Review: As advertised! - Another quality tool from Park. Perfect fit!
