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! ## Features - Ideal Product - Anodized for easy identification - Features a ratchet/torque wrench-compatible 3/8" drive.NOTE: The BBT-27.3 does not fit Hope BSA30 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09T7B6K1P | | Best Sellers Rank | #121,687 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #391 in Bike Shop Tools | | Brand | Park Tool | | Brand Name | Park Tool | | Color | Multi-coloured | | Customer Reviews | 4.8 out of 5 stars 56 Reviews | | Head Style | Box End | | Included Components | power tools and accessories | | Item Length | 49 millimeters | | Item Package Quantity | 1 | | Item Type Name | Tools and accessories | | Item Weight | 2.72 ounces | | Manufacturer | PARK TOOL | | Manufacturer Part Number | BBT-27.3 | | Material | Aluminum | | Material Type | Aluminum | | Measurement Standard | Metric | | Model Number | 4003130 | | Package Quantity | 1 | | UPC | 763477001368 | ## Product Details - **Brand:** Park Tool - **Color:** Multi-coloured - **Item Length:** 49 Millimeters - **Item Weight:** 2.72 ounces - **Material:** Aluminum ## Images ![Park Tool Tool BBT-27.3 16-Notch 49mm - Image 1](https://m.media-amazon.com/images/I/61WuC2LT2UL.jpg) ![Park Tool Tool BBT-27.3 16-Notch 49mm - Image 2](https://m.media-amazon.com/images/I/61STOvq9P7L.jpg) ![Park Tool Tool BBT-27.3 16-Notch 49mm - Image 3](https://m.media-amazon.com/images/I/61+hVvEH+8L.jpg) ![Park Tool Tool BBT-27.3 16-Notch 49mm - Image 4](https://m.media-amazon.com/images/I/81htlQybG3L.jpg) ![Park Tool Tool BBT-27.3 16-Notch 49mm - Image 5](https://m.media-amazon.com/images/I/71glEnDq1PL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ So important to have the right tools for the job *by J***N on April 17, 2023* 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.
