Although the dimensions seemed to be right, it didn't fit. It looks like a nice quality tool though. I don't fully understand the bottom bracket sizing and how to make them work.. Anyway I just ended up getting an ultegra BB from a friend, and borrowing the appropriate tool from him to tighten it. Note: this tool didn't fit the ultegra BB either. Maybe Park Tool can come up with a guide or chart on what tool to use with what BB? Maybe someone has already done that? I don't know.... Review: Good BB tool - One of many BB standards...so check your size. This one works great, serves its purpose, no complaints. ## Features - Double-ended bottom bracket wrench - Smaller end fits 16-notch bearing cups with an outside diameter of 39mm (i.e. Shimano Dura-Ace 9000 series and XTR 980 series) - Larger end fits 16-notch bearing cups with an outside diameter of 48.5mm (i.e. FSA MegoEvo) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00DX5X48E | | Best Sellers Rank | #220,100 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #724 in Bike Shop Tools | | Brand | Park Tool | | Brand Name | Park Tool | | Color | Silver | | Customer Reviews | 4.6 out of 5 stars 278 Reviews | | Finish Types | Pulverbeschichtet | | Global Trade Identification Number | 00763477000583 | | Head Style | Ringratschenmaulschlüssel | | Included Components | Crank, Bottom Bracket & Pedals | | Item Highlight | Park Tool BBT-29 Double-Ended Bottom Bracket Wrench for 39mm & 48.5mm Cranks | | Item Length | 39 millimeters | | Item Package Quantity | 1 | | Item Type Name | Workshop | | Item Weight | 0.22 kg | | Manufacturer | Park Tool | | Manufacturer Part Number | QKBBT29 | | Manufacturer Warranty Description | Limited Lifetime Warranty - see Parktool.com/warranty for details | | Material | Plastic | | Material Type | Plastic | | Model Number | QKBBT29 | | Number of Items | 1 | | Number of Packs | 1 | | Operation Mode | Mechanical | | Package Quantity | 1 | | UPC | 784427871299 763477000583 757183513611 | | Unit Count | 1 Count | ## Product Details - **Brand:** Park Tool - **Color:** Silver - **Item Length:** 39 millimeters - **Item Weight:** 0.22 kg - **Material:** Plastic ## Images ![Tretlager BBT-29 16-Kerbbecher Werkzeug 39mm/48,5mm - Image 1](https://m.media-amazon.com/images/I/717kytrwXKL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice piece, but it didn't work for me. *by S***Y on July 6, 2019* I bought this to tighten the bottom bracket that came with my Shimano 105 R7000 setup.
